Phosphate fertilization improves banana yields, but due to the physiological effects of phosphorus on plants, it can also be used to improve the physical and chemical characteristics of the fruits, which can contribute to increasing the processing of green bananas and reducing losses in the production chain. Herein, the productivity of bunches and fruit, the biometric analysis of the fruit, dry matter content, and the chemical composition of immature fruit were evaluated when the cultivar BRS SCS Belluna (AAA) was grown under different levels of phosphate fertilization for two harvest cycles. The results showed that phosphate fertilizer levels interfered with bunch yield and fruit mass in both cycles, leading to yield gains of 44.3% (1st cycle) and 84.0% (2nd cycle) in bunches and 51.8% (1st cycle) and 81.9% (2nd cycle) in fruits. Fertilization promoted gains of up to 33.5% in fruit mass and enhanced the resistant starch content in the pulp, leading to an increase of 15.1%. The phosphorus, potassium, and calcium contents in green fruits increased with fertilizer levels in the first cycle, improving nutritional quality. These results have useful applications because they indicate that adequate management of phosphate fertilization can increase the potential of the cultivar for industrial processing of green fruits and the nutritional quality of the derived products.

Background and Objectives: This study aimed to evaluate the effects of milk and banana given as a bedtime snack to patients with primary insomnia on sleep parameters and some biochemical parameters such as brainderived neurotrophic factor, leptin, and ghrelin. Methods and Study Design: 21 patients with insomnia who met the inclusion criteria participated in this study. The patients were divided into 3 parallel groups: banana, milk and control. The intervention group were given either 1 portion of banana or just 200 mL of whole-fat milk at bedtime. The control group did not consume any non-routine food. Venous blood samples were taken at baseline and after the study from patients to measure brain-derived neurotrophic factor, leptin and ghrelin concentrations. Sleep quality and architecture were determined by polysomnography and Pittsburg Sleep Quality Index. Results: Pittsburg Sleep Quality Index scores of the banana and milk group were found to be lower after intervention (p<0.05). In terms of polysomnography, the total sleep time of the milk group was found to be significantly higher than baseline. Serum ghrelin concentration of the milk group decreased significantly compared to baseline. Conclusions: Bedtime milk or banana intake was effective in dealing with insomnia. Foods rich in tryptophan, such as banana and milk, given at bedtime, may improve sleep parameters and appetite hormones. [ABSTRACT FROM AUTHOR]

Since its invasion of Kerala in 2014, the banana skipper Erionota torus Evans (Lepidoptera: Hesperiidae) has become a severe threat to banana farming. The present study reports phorid fly Megaselia scalaris (Loew), a prominent detritivorous insect, as a parasitoid attacking the pupa of Banana leaf roller E. torus Evans. This parasitoid was reported for the first time in the field population of banana leaf roller pupa collected from Pariyaram located at 12.0753N, 75.3049E, Kannur district of Kerala, India, during August, 2019. By using both classical and molecular methods, we were able to confirm the species. The current research suggests that M. scalaris might be included to the list of parasitoid species that are known to exist for E. torus pupa. More research is needed to determine whether or not this phorid fly can be used as an efficient biocontrol agent. [ABSTRACT FROM AUTHOR]

BANANAS ,LIGNOCELLULOSE ,NATURAL fibers ,COCHINEAL insect ,FOURIER transform infrared spectroscopy - Abstract
Banana (Musa x paradisiaca L.) is a lignocellulosic natural fiber that can be processed to produce eco-friendly and biodegradable hybrid fabrics when combined with other fibers. Natural-dyed banana fiber can be utilized in the production of sustainable materials for wearable products, household linens, technical textiles, and apparel. In this study, banana-silk union fabrics, pre-treated with bio-mordant at concentrations of 1%, 2%, 3%, 4%, and 5%, were dyed separately using cochineal insect extract (Dactylopius coccus Costa). To assess the dyeability of the banana-silk union fabric, Anatolian black pine cones (Pinus nigra subsp. pallassiana) were utilized as a bio-mordant, with varying quantities. The CIELab values of the dyeings were measured and compared. Additionally, the chemical composition of the cochineal extract, pinecone mordant, raw fabric, and selected dyed fabrics was analyzed using Fourier Transform Infrared (FTIR) spectroscopy. The washing, light, and rubbing fastness properties of the dyed banana-silk union fabrics were also evaluated and compared. This study developed a method for weaving union fabric by blending two distinct natural yarns, namely banana and silk, to reduce dependence on a single fiber and promote the utilization of agricultural waste.

This study investigated the functional and nutritional properties of two banana peel flours from Lampung Province, an underutilized agro-industrial waste, BPF-J (Janten) and BPF-K (Kepok). These flours were evaluated as potential substitutes for wheat flour and other functional foods. The banana peels were treated with anti-browning agents and dried at 50 °C for 18 h. Notable nutritional differences were observed: BPF-J contained higher protein, starch, and soluble dietary fiber in g/100 g (7.04, 49.90, and 6.18, respectively), whereas BPF-K had higher fat content, insoluble dietary fiber, and total dietary fiber in g/100 g (12.26, 44.33, and 47.08, respectively). The phenolic content of BPF-J was comparable to that of BPF-K (50.52 and 49.75 mg GAE/100 g dry weight). The highest mineral contents in BPF-J were Fe, Zn, Mg, and K (mg/kg) at 31.82, 16.00, 105.76, and 3705.9, respectively. Conversely, BPF-K had higher Ca and Mn contents (472.02 and 15.68 mg/kg). BPF-K exhibited a higher water holding capacity owing to its higher dietary fiber content. Both flours exhibited similarities in oil holding capacity and swelling power. BPF-J exhibited higher solubility at 70 °C. The pasting properties revealed distinct differences, with BPF-K demonstrating a lower pasting temperature and higher viscosity. Morphologically, BPF-J contained more exposed starch granules than BPF-K, whereas BPF-K displayed a predominantly fibrous matrix. These flours were tested in biscuit formulations, and the 20% BPF-J biscuits showed the best sensory acceptability. These findings suggest that BPF-J and BPF-K are viable and sustainable options for enhancing functional food products. [ABSTRACT FROM AUTHOR]

This study is aimed at documenting the indigenous knowledge and quantitative analysis of medicinal plants (MPs) used by traditional health practitioners (THPs) of Urambo District in mid‐western Tanzania to manage respiratory tract disorders (RTDs). The ethnomedicinal data were collected using semistructured interviews with 55 THPs using a snowballing technique in the district. The data were analysed for indigenous knowledge among gender, age groups, education status, and experience. Family importance value (FIV), use value (UV), relative frequency of citation (RFC), informant consensus factor (ICF), and Jaccard index (JI) were computed. A total of 42 MPs representing 28 families were recorded being used against RTDs in the district. Fabaceae was the dominant family in terms of species (16.7%) and FIV (84%). Decoction (51.0%) was the preferred technique for preparing remedies, while trees (61.9%) and leaves (38.1%) were the most utilised life form and plant parts, respectively. The RFC in the current study varied from 0.055 (Musa paradisiaca L.) to 0.655 (Zingiber officinale Roscoe) and 0.073 (Dichrostachys cinerea (L.) Wight & Arn.) to 0.673 (Entada abyssinica Steud. ex A.Rich.), respectively. The highest ICF was recorded for cough (0.922). The JI ranged from 2.7 to 7.9. Among the documented MPs, 55% had least concern, 2% were endangered, 7% had data deficiency conservation status, and 36% had no record in the IUCN Red List. The study revealed that the district's population depends on MPs for healthcare. Thus, conservation strategies are needed for the sustainable utilisation of the MPs. Importantly, the documented MPs hold immense potential in future pharmacological and phytochemical studies, offering hope for the development of new drugs for RTDs. Also, the study suggests the need for scientific validation of the MP's efficacy and safety. [ABSTRACT FROM AUTHOR]

VOLATILE organic compounds ,AGRICULTURAL productivity ,ACTIVATED carbon ,ADSORPTION capacity ,BANANAS ,ETHYL acetate - Abstract
Activated carbons were prepared from residues from agro-industrial banana production (banana pseudostem) and evaluated in the capture of five different volatile organic compounds (VOCs): dichloromethane, chloroform, ethyl acetate, hexane, and cyclohexane. The biomass was first submitted to a hydrothermal treatment in the presence of KOH or ZnCl
2 as activating agents, followed by a dry pyrolysis. This new advance in methodology contributes to producing activated carbons with hierarchical porosity and high surface areas (701–1312 m2 g−1 ), promoting increased interest in managing waste from banana fruit agricultural production. VOC capture studies were performed by thermal analysis, and capture capacities were similar to or higher than those presented in the literature. Higher adsorption capacities were related to the amount of available micropores, and the capture capacity was enhanced by the contribution of small mesopores. As the highest adsorbed amounts of dichloromethane (933 mg g−1 at 25 °C) were obtained for the material activated with ZnCl2 (1:3), further studies were carried out for this system. The experimental data was fitted using a pseudo-first-order kinetic model. A study was carried out in different atmospheres (He, N2 , air), showing that co-adsorption is occurring. Under simulated environmental conditions, the capture capacity decreased slightly at equilibrium, and the new adsorbent was used for up to ten cycles without significantly losing its efficiency, indicating good application in the field.

Bananas (Musa spp.) are among the most important fruit and staple food crops globally, holding a significant strategic position in food security in tropical and subtropical regions. However, the industry is grappling with a significant threat from Fusarium wilt, a disease incited by Fusarium oxysporum f. sp. cubense (Foc). In this study, we explored the potential of Piriformospora indica (Pi), a mycorrhizal fungus renowned for bolstering plant resilience and nutrient assimilation, to fortify bananas against this devastating disease. Through a meticulous comparative analysis of mRNA and miRNA expression in control, Foc-inoculated, Pi-colonized, and Pi-colonized followed by Foc-inoculated plants via transcriptome and sRNAome, we uncovered a significant enrichment of differentially expressed genes (DEGs) and DE miRNAs in pathways associated with plant growth and development, glutathione metabolism, and stress response. Our findings suggest that P. indica plays a pivotal role in bolstering banana resistance to Foc. We propose that P. indica modulates the expression of key genes, such as glutathione S-transferase (GST), and transcription factors (TFs), including TCP, through miRNAs, thus augmenting the plant's defensive capabilities. This study offers novel perspectives on harnessing P. indica for the management of banana wilt disease. [ABSTRACT FROM AUTHOR]

Metarhizium anisopliae (Metschnikoff) Sorokin and Beauveria bassiana (Balsamo) Vuillemin are entomopathogenic fungi commonly used in microbial control of arthropods. In this study, we evaluated the insecticidal potential of six isolates of B. bassiana (BIITAC10.3.3, BIITAC6.2.2, and BIITAC8.1.5) and M. anisopliae (MIITAC11.3.4, MIITAC6.2.2, and MIITAC6.4.2) from Cameroon, against the banana aphid Pentalonia nigronervosa Coquerel, the vector of the banana bunchy top virus (BBTV). Pathogenicity tests were initially conducted using B. bassiana and M. anisopliae isolates at a concentration of 3.2 × 106 conidia/ml on P. nigronervosa adults sourced from four agroecologies in Cameroon. Four isolates (BIITAC6.2.2, BIITAC10.3.3, BIITAC8.1.5, and MIITAC6.2.2) were highly pathogenic, causing greater than 75% aphid mortality in all populations. A significant decrease in aphid fecundity was observed with BIITAC6.2.2, MIITAC6.2.2, and BIITAC10.3.3. These three isolates were in a test of a series of four fungal concentrations (3.2 × 101, 3.2 × 102, 3.2 × 104, and 3.2 × 106 conidia/ml). produced LC50 of 1.31 × 101 and 3.12 × 10−2 for BIITAC10.3.3 and MIITAC6.2.2, respectively. MIITAC6.2.2 had the lowest LC90 (1.55 × 103). Our results strongly support the continued development of biopesticides based on one or more of the three fungal entomopathogens for the control of banana aphids as a component of an Integrated Pest Management (IPM) strategy for the reduction of the prevalence and transmission of BBTV under field conditions.

Bananas rapidly undergo physiological deterioration after harvest owing to their climacteric and perishable nature causing significant economic yield loss. Thus, the adoption of postharvest loss mitigation strategies becomes imperative for enhancing fruit longevity. This study aimed to assess the effect of postharvest treatment with different concentrations of aminoethoxyvinylglycine (AVG) on shelf life extension and quality sustainability of bananas, such as Grand Naine, Poovan and Ney Poovan, kept under ambient (27°C ± 2°C) and cool (17°C) conditions. The findings revealed that AVG-treated bananas reduced weight loss of banana hands (0.655–2.559 kg hand−1) and higher peel thickness (0.86–2.73 mm) and firmness (6.54–12.01 N) over untreated control at ambient storage condition, whereas under cool storage, weight loss of banana hands reduced from 0.761 to 2.579 kg hand−1, while both peel thickness (1.24–2.84 mm) and firmness (7.75–11.45 N) were retained for varieties. The physio-chemical traits of fruit, such as total chlorophyll and starch content, were improved due to AVG treatment under both storage conditions. Among the treatments, postharvest application of AVG at 700 ppm showed better performance in the morphological, physiological and quality characters irrespective of the varieties.

The primary aim of this study was to investigate the impact of educational attainment on entrepreneurial competence and financial risk tolerance among small-scale banana growers. Employing a descriptive-correlational research design with a complete enumeration sampling technique and moderation analysis, data were gathered from 150 small-scale banana growers in Compostela, Davao de Oro. The findings reveal a high level of entrepreneurial competence and financial risk tolerance among the growers. There is a significant relationship between entrepreneurial competence and financial risk tolerance. However, the interaction between entrepreneurial competence and educational attainment had an insignificant effect on the level of financial risk tolerance. This implies that entrepreneurial competence is associated with greater financial risk tolerance regardless of educational attainment, highlighting pathways for enhancing small-scale agriculture's contribution to economic growth and sustainability. This study aligns with the Sustainable Development Goals (SDGs), particularly SDG 2 (Zero Hunger) and SDG 8 (Decent Work and Economic Growth), by identifying factors that support sustainable agricultural practices and entrepreneurship among small-scale growers. Our findings suggest that fostering entrepreneurial competence can contribute to achieving these goals by enhancing the productivity, sustainability, and financial resilience of small-scale banana growers in developing regions.

Banana is an important fruit and food crop in tropical and subtropical regions worldwide. Banana production is seriously threatened by Fusarium wilt of banana (FWB), a disease caused by Fusarium oxysporum f. sp. cubense, and biological control is an important means of curbing this soil-borne disease. To reveal the effects of biocontrol agents on inhibiting FWB and altering the soil bacterial community under natural ecosystems, we conducted experiments at a banana plantation. The control efficiency of a compound microbial agent (CM), Paenibacillus polymyxa (PP), Trichoderma harzianum (TH), and carbendazim (CA) on this disease were compared in the field. Meanwhile, the alterations in structure and function of the rooted soil bacterial community in different treatments during the vigorous growth and fruit development stages of banana were analyzed by microbiomics method. The results confirmed that the different biocontrol agents could effectively control FWB. In particular, CM significantly reduced the incidence of the disease and showed a field control efficiency of 60.53%. In terms of bacterial community, there were no significant differences in the richness and diversity of banana rooted soil bacteria among the different treatments at either growth stage, but their relative abundances differed substantially. CM treatment significantly increased the ratios of Bacillus, Bryobacter, Pseudomonas, Jatrophihabitans, Hathewaya, and Chujaibacter in the vigorous growth stage and Jatrophihabitans, Occallatibacter, Cupriavidus, and 1921-3 in the fruit development stage. Furthermore, bacterial community function in the banana rooted soil was affected differently by the various biocontrol agents. CM application increased the relative abundance of multiple soil bacterial functions, including carbohydrate metabolism, xenobiotic biodegradation and metabolism, terpenoid and polyketide metabolism, lipid metabolism, and metabolism of other amino acids. In summary, our results suggest that the tested biocontrol agents can effectively inhibit the occurrence of banana Fusarium wilt and alter the soil bacterial community in the field. They mainly modified the relative abundance of bacterial taxa and the metabolic functions rather than the richness and diversity. These findings provide a scientific basis for the use of biocontrol agents to control banana Fusarium wilt under field conditions, which serves as a reference for the study of the soil microbiological mechanisms of other biocontrol agents.

Gluten‐free diets are characterized by lower nutritional quality. The use of green plantain flour in gluten‐free formulations appears as an alternative to overcome this deficiency, considering that green plantains have a relevant content of bioactive compounds, dietary fiber, including resistant starch. The objective of this work was to evaluate the effect of the addition of native and modified by hydrothermal treatment green plantain whole flours in the form of gluten‐free cupcakes. The density, yield, and microstructure of the dough, specific volume (SV), height, crumb analysis, color, texture, and sensory acceptability of the cupcakes were evaluated. Partial replacement (40%) of rice flour by native and modified flours produced darker, redder cupcakes, less yellowish and with less color intensity. Sensory analysis revealed higher acceptance for cupcakes with native and modified flours, compared to the control, for appearance, flavor, texture, aroma, and overall acceptance. The native flour was the most viable option, as the cupcake produced with it showed the best values for hardness and chewiness, without changing elasticity and SV, in addition to superior sensory acceptance than the control and similar to cupcakes with other modified flours. Practical Application: Pursuing to meet the market demand for gluten‐free products, with the cake being one of the most requested products in this market, and taking in account that green banana, from different cultivars, has gained interest for the production of flours. The production of flour and bakery products is of great interest to the food industry, not only because of its flavor and properties but also due to the economic and sustainable viability of producing whole green plantain flour with the potential for application, promoting diversification and innovation in the gluten‐free functional products market.

Bananas (Musa spp.) are a popular tropical fruit grown worldwide and are typically harvested when 70% to 80% plump. Postharvest storage is crucial for maintaining fruit quality, with temperature playing a key role due to banana sensitivity to low temperatures. Red peeled bananas, such as the cultivar Hongmeiren, stand out for their unique red peel and pink pulp when ripe. These bananas offer nutritional benefits and are rich in anthocyanins compared with yellow bananas. This study focused on the hardness change, anthocyanin content, and the expression of related genes in red peeled bananas at different temperatures. Results showed that pulp hardness reached an edible state after 4 days at 19 and 25 °C, with stability thereafter. Storage time at 10 °C was longer and anthocyanin content remained stable across temperatures. Gene expression analysis indicated that genes including MaPAL, MaCHS, MaCHI, MaDFR, and MaANS related to anthocyanin synthesis were highly expressed at 10 °C, potentially preserving anthocyanin content and fruit appearance. Although higher anthocyanin content was observed at 19 and 25 °C, black spots appeared on the fruit peel after 8 days, affecting its quality. After 30 days of storage at 10 °C, a significant number of black spots appeared on the peel of the fruit, leading to a gradual loss of its nutritional value. This study indicates that red peeled bananas can be stored for longer periods while maintaining their appearance quality at 10 °C, as opposed to 19 and 25 °C. Hence, it is recommended to store red peeled bananas at low temperatures, especially following ethylene treatment or during periods of high temperatures. [ABSTRACT FROM AUTHOR]

This study aimed to develop the application of 405 nm LEDs to reduce the spoilage risk of bananas in the distribution chain. Fusarium oxysporum was spread-plated onto dichloran rose bengal chloramphenicol agar and illuminated with an array of 405 nm light emitting diodes at mean irradiances ranging from 0.5–2.2 mW/cm2. A minimum irradiance of 2.2 ± 0.9 mW/cm2 was required to bring about an antifungal effect, with the mold population reduced below the detection limit within 6 h of illumination. This was attributed to the presence of porphyrins (5.46 ± 2.49 fg/CFU) in the F. oxysporum spores, as determined by high pressure liquid chromatography. A statistically significant (P > 0.05) 70% reduction was observed relative to the control group when the bananas were spot-inoculated on their stem scar with Fusarium, stored under simulated warehouse conditions (15.0 °C and 80.0% RH for 24 h) and illuminated with 2.2 ± 0.9 mW/cm2 for 48 h under simulated retail conditions (25.5 °C and 63.5% RH for another 54 h). The control group was kept in the dark under the same conditions otherwise. The illumination did not produce any significant difference (P > 0.05) in the appearance, peel color, mass and hardness of the bananas. A slight decrease in the activity of polyphenol oxidase, the enzyme responsible for browning, was also observed. These results suggest that 405 nm LED illumination has the potential to reduce the risk of Fusarium spoilage of bananas in supermarkets while preserving the physicochemical properties that influence the consumers' purchase.

LIPID peroxidation (Biology) , *STARCH metabolism , *HIGH temperatures , *BANANAS , *HUMIDITY - Abstract
During transportation and storage after harvest, bananas exhibit an abnormal phenomenon called "green-soft," where the pulp softens prematurely while the peel remains green and hard. To understand the mechanism of abnormal softening of banana pulp, the influence of high temperature (35 °C) and high humidity (saturated humidity) on the intrinsic physiology of the pulp was investigated from the aspects of ROS metabolism, membrane lipid peroxidation, and starch metabolism. The results showed that hardness of the bananas stored in high humidity and high temperature decreased by 77% at 14 days compared to control, suggesting that the combined treatment of high temperature and high humidity caused the formation of the banana "green-soft" phenomenon. Further analysis showed that ROS content was significantly increased (33%), membrane lipid peroxidation was intensified (460%), starch content was significantly reduced (68%), and cellular integrity was disrupted during this process. This work clarifies the potential mechanisms of abnormally softened banana pulp and provides a detailed theoretical foundation for the study of "green-soft" banana. [ABSTRACT FROM AUTHOR]

The banana mealybug Pseudococcus elisae Borchsenius (Hemiptera: Coccomorpha: Pseudococcidae) is a pest of economic importance in Cameroon that requires effective control practices, especially after the routinely used chlorpyrifos insecticide was banned in 2019. For effective mealybug control, it is imperative to understand their ecology in relation to banana growth stages and climate‐induced seasonal variations. Therefore, the influence of climatic variables and banana growth stages on a spatio‐temporal distribution of mealybugs in Esuke and Benoe banana plantations of the Cameroon Development Corporation in Tiko was assessed.A 60‐ha area was mapped in each plantation and divided into 12 plots of 5 ha each, which were further sub‐divided into four quadrants of 1.25 ha. A total of 10 banana suckers, 10 pre‐flowering, 10 flowering and 10 bunchy plants were sampled per quadrant.Monthly mealybug population dynamics were assessed across 2 years in 2021 and 2022 on lower or upper pseudostem, leaves and banana bunches.Significant yearly and monthly mealybug population variation on banana plants were observed, with more mealybugs in 2022 than 2021, and two monthly mealybug peaks in February and November (p < 0.001). Mealybug population was higher on banana bunches and lower or upper pseudostem than on leaves (p < 0.001). Mealybugs preferred bunchy plants than suckers or pre‐flowering and flowering plants, and exhibited clumped distribution with Taylor aggregation index (b) greater than one (p < 0.001). A simple linear regression revealed strong positive effects of high temperature on mealybug population ecology, while relative humidity and rainfall had inverse effects on the population of mealybug.These highlight the dynamics of banana mealybug population ecology under variable climatic conditions and banana growth stages, which provides valuable baseline information to facilitate developing effective control strategies for mealybugs in banana plantations.

Banana is one of the most important crops produced globally. It contains a wide variety of valuable compounds and has interesting functional properties. Moreover, many by-products and wastes are generated from its collection to its consumption. Bananas are highly perishable due to their high moisture content and an appropriate post-harvest technology and agricultural engineering would prolong its shelf life. Drying is an important and the widely used method of food processing. In addition, drying can also promote the development of value-added products. The quality of dried banana is highly dependent upon the drying method and conditions. Conventionally, bananas are sun- or hot-air-dried. However, these methods are often slow processes and the products obtained have poor quality, so other alternate drying technologies have been developed. This review focuses upon conventional and new drying technologies and pre-treatment methods. The hybrid drying techniques minimize the undesirable effects of drying on banana quality, improve the drying efficiency and provide superior quality products. [ABSTRACT FROM AUTHOR]

Effectively regulating anger driving has become critical in ensuring road safety. The existing research lacks a feasible exploration of anger-driving regulation. This paper delves into the effect and neural mechanisms of emotional olfactory stimuli (EOS) on regulating anger driving based on EEG. First, this study designed an angry driving regulation experiment based on EOS to record EEG signals. Second, brain activation patterns under various EOS conditions are explored by analyzing functional brain networks (FBNs). Additionally, the paper analyzes dynamic alterations in anger-related characteristics to explore the intensity and persistence of regulating anger driving under different EOS. Finally, the paper studies the frequency energy of EEG changes under EOS through time–frequency analysis. The results indicate that EOS can effectively regulate a driver's anger emotions, especially with the banana odor showing superior effects. Under banana odor stimulus, synchronization between the parietal and temporal lobes significantly decreased. Notably, the regulatory effect of banana odor is optimal and exhibits sustained efficacy. The regulatory effect of banana odor on anger emotions is persistent. Furthermore, the impact of banana odor significantly reduces the distribution of high-energy activation states in the parietal lobe region. Our findings provide new insights into the dynamic characterization of functional connectivity during anger-driving regulation and demonstrate the potential of using EOS as a reliable tool for regulating angry driving.

Plant tissue culture biotechnology offers a sustainable way to adapt to climate change by propagating disease-free plants with the desired traits. This study investigated stakeholders' agronomic, social and economic evaluation of tissue culture plants (TCPs). It unravels micro-level outcomes and indicators that determine TCPs evaluation through a systematic literature review. The 35 articles examined show an imbalance of studies in the three evaluation streams, with social studies on horticultural crops, especially bananas in developing countries, dominating. The results of the TCPs evaluation vary considerably between stakeholders. The main determinants of evaluation are TCPs attributes. TCPs are very knowledge-intensive and costly to establish and manage. Therefore, customising of TCPs to local conditions and closer collaboration between stakeholders are essential for successful implementation. Advisory services, social entrepreneurship and networks are needed to create knowledge-sharing platforms and ecosystems. While single-stream evaluations reveal TCPs superiority over conventionally propagated crops, it is suggested that an integrated assessment be undertaken to combine social, economic, and agronomic indicators and evaluate the technology simultaneously.

This manuscript focuses on the development of Fruit Storage Chamber (FSC) equipped with nano-TiO
2 and its modular prototype to improve the value of bamboo-based FSC by its photocatalytic and feasibility aspects. Its effects on fruit shelf life and ripening-related gene expression were studied. Cavendish bananas were stored in FSC equipped with nano-TiO2 and modular FSC for treatments. Relative expression level of ethylene biosynthesis-related (MaACS1, MaACO1) and polyphenol oxidase (MaPPO4, MaPPO5) genes were examined. The dynamics of ripening variables throughout the storage period were illustrated in regression lines, followed with hypothesis testing. Banana quantity showed no significant changes upon storage in FSC equipped with nano-TiO2 . Physical appearance indicated a ripening delay of up to two days on nano-TiO2 treatments compared to control. Ethylene production rate and ethylene related gene expression were not significantly altered. Browning index was more maintained in nano-TiO2 treated samples, supported by the observation of slower increase of MaPPO4 and MaPPO5 relative expressions compared to control. The findings highlight the suppression of fruit ripening related gene expression and the maintenance of fruit quality in treated samples compared to control, indicating the potential use of nano-TiO2 to prolong banana shelf life.

Although adding flocculants is an essential step in wastewater treatment and maintaining the stability of the solid-state in solution to produce a loose cell-like structure, in some instances, polymeric material fails to support this due to specific surface charges. Therefore, the current study aimed to develop a cationic form (CBS) obtained from unripe waste bananas as native starch and characterize it as a flocculating agent. The starch from unripe waste banana fruit peel was extracted and synthesized to CBS using an etherification reaction via grafting a cationic moiety such as 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). In addition, the synthesis process was optimized using quality by design (QBD). The utilization of QBD led to the attainment of the maximum degree of substitution (DS) value of 0.623 under optimal circumstances, which involved reacting moieties such as CHPTAC (0.007 moL) and NaOH (30% w/v) with a reaction duration of 18 h at a temperature of 50 °C. Moreover, elemental, structural, x-ray diffraction, thermal analysis, and surface morphology indicated that a significant cationic fraction was integrated within the BS. In addition, the biocompatibility study showed that both native BS and CBS were > 95% biocompatible against CaCO-2 and HeK-293 cells. Furthermore, the flocculation performance of CBS showed that the transmittance of the supernatant fluid augmented in direct correlation to the sedimentation and flocculation time for CBS. Thus, the modified CBS can be utilized as an economical, safe, and potential substitute against available flocculating agents. [ABSTRACT FROM AUTHOR]

In an open-air market in southern Italy, we noticed 'Lady finger' banana fruit imported from Costa Rica showing a severe rot, whose symptoms consisted of necrotic peel lesions with variable shape and size. Fusarium sacchari and F. proliferatum were consistently isolated from symptomatic fruit. In pathogenicity tests on 'Lady finger' banana fruit, F. proliferatum was more virulent than F. sacchari. Quantitative Time-of-Flight Mass Spectrometric analysis of secondary metabolites produced by isolates of these two Fusarium species on three different matrices (banana peel, barley and maize kernels) identified 11 mycotoxins. Seven of them (Fusaproliferin, Fumonisins A
1 , Fumonisins A2 and Fumonisins B1 , Hydrolysed Fumonisin B1 , Fusarin C and Moniliformin) were detected in matrices contaminated by F. proliferatum isolates. Fumonisin A1 was the prevalent mycotoxin in both maize kernels and banana peel, while Fumonisin A2 prevailed in barley kernels. Similarly, seven mycotoxins (the cyclic hexadepsipeptides Enniatins B2 , B3 and B4 , Fumonisins A1 and B2 , Hydrolysed Fumonisin B1 and Fusarin C) were detected in matrices contaminated by F. sacchari isolates, but they were only in part the same as those produced by F. proliferatum isolates. Fusarin C prevailed in all three matrices colonized by F. sacchari. Fumonisin A1 was detected exclusively in maize kernels while Enniatins B3 and B4, Fumonisin B2 and Hydrolysed Fumonisin B1 were detected exclusively in barley kernels. Overall, F. proliferatum produced a higher amount of mycotoxins than F. sacchari. Moreover, in banana peel both species produced a lower number and amount of mycotoxins than in the other two matrices. [ABSTRACT FROM AUTHOR]- Published

This study aimed to compare the effects of incorporating fermented feed into daily diets on the slaughter performance, meat quality, and flavor compounds of 120 domestic chickens over a 140-day period. A total of five groups (n = 24), including the control group (CK) of the Guangxi Partridge chickens received a standard base diet. The other four groups were provided with pellets that had been added with 10% fermented banana peel (Pe-10), 20% fermented banana peel (Pe-20), 10% fermented banana pulp residue (Pu-10), and 20% fermented banana pulp residue (Pu-20). The flavor compounds in the meat samples of the chickens in these groups were determined using the gas chromatographic method. The results demonstrated that the chickens in the Pe-10, Pe-20, Pu-10, and Pu-20 groups exhibited pectoral muscle percentages, thigh muscle percentages, and total fatty acid content of chest meat that were higher than those observed in the CK group. The moisture content, meat color, carcass weight, total net weight, and abdominal fat percentage of the meat samples in these experimental groups exhibited no notable differences. The flavor compounds in the meat samples of the chickens fed with the two concentrations of fermented banana peel and banana residue were found to be significantly different from those in the control group, with p-values less than 0.05. As the quantity of fermented banana peel incorporated into the daily ration was increased from 10% to 20%, a notable alteration in the flavor compounds present in the chicken samples was observed. The chickens that were provided with fermented banana peels and pulps in their diets exhibited superior slaughter performance and meat quality, particularly in the case of the Pu-10 group, in comparison to the control chickens.

Faster ripening and senescence of banana fruit is closely associated with higher ethylene production and oxidative damages. Present study evaluated the mechanism of sodium nitroprusside (as a nitric oxide donor) on delayed ripening and senescence in banana as well as mitigating the oxidative damage. Nitric oxide (NO) was applied to fruit by vacuum infiltration (1 mM) and stored for 8 days at 25 °C with 65–70% relative humidity. Fruit quality, electrolytic leakage, phenolic content, reactive oxygen species production and scavenging activity were investigated. The results showed that NO treated fruit retained higher phenolics, antioxidant capacity (radical scavenging activity), and reduced electrolytic leakage, malondialdehyde (MDA) content and free radical production (H
2 O2 and O2 − ) than control on the last day. The inhibitory effect of NO on ripening was observed with delayed chlorophyll loss as well as reduced ethylene and CO2 production rate in banana during storage. Therefore, vacuum infiltrated NO could be a possible postharvest treatment for mitigating the oxidative damages and preserving banana fruit up to 8 days at ambient condition.

Introduction: Fusarium wilt of banana, also recognized as Panama disease, is caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense tropical race 4 (FOC TR4). In recent years, strategies utilizing biocontrol agents, comprising antifungal microorganisms and their associated bioactive compounds from various environments, have been implemented to control this destructive disease. Our previous study showed that Pseudomonas aeruginosa Gxun-2 had significant antifungal effects against FOC TR4. However, there has been little scientific investigation of the antibacterial or antifungal activity. The aim of this study was to isolate, identify and evaluate the inhibition strength of active compounds in P. aeruginosa Gxun-2, so as to explain the mechanism of the strain inhibition on FOC TR4 from the perspective of compounds. Methods: The main antibacterial compounds of strain Gxun-2 were isolated, purified and identified using by fermentation extraction, silica gel column chromatography, thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), and nuclear magnetic resonance (NMR) techniques. The effect of the compounds on the mycelial growth, morphology and spore germination of strain FOC TR4 was observed by 96-well plate method and AGAR diffusion method. Results: Among the metabolites produced by the strain, four antifungal compounds which were identified phenazine (C
12 H8 N2 ), phenazine-1-carboxylic acid (PCA) (C13 H8 N2 O2 ), 2-acetamidophenol (C8 H9 NO2 ) and aeruginaldehyde (C10 H7 NO2 S) were identified through HPLC and NMR. Of these compounds, phenazine and PCA exhibited the most pronounced inhibitory effects on the spore germination and mycelial growth of FOC TR4. Phenazine demonstrated potent antifungal activity against FOC TR4 with a minimum inhibitory concentration (MIC) of 6.25 mg/L. The half-maximal effective concentration (EC50 ) was calculated to be 26.24 mg/L using the toxicity regression equation. PCA exhibited antifungal activity against FOC TR4 with an MIC of 25 mg/L and an EC50 of 89.63 mg/L. Furthermore, phenazine and PCA triggered substantial morphological transformations in the mycelia of FOC TR4, encompassing folding, bending, fracturing, and diminished spore formation. Discussion: These findings indicate that strain Gxun-2 plays a crucial role in controlling FOC TR4 pathogenesis, predominantly through producing the antifungal compounds phenazine and PCA, and possesses potential as a costefficient and sustainable biocontrol agent against Fusarium wilt of banana in forthcoming times.

The lack of proper cleaning and sanitizing practices on natural food-contact surfaces can lead to foodborne illness outbreaks. This study was conducted to evaluate the efficacy of cleaning and sanitizing methods for reducing Salmonella inoculated onto banana leaf and bamboo basket surfaces. Surfaces were inoculated with a Salmonella cocktail and assigned to a combination treatment of cleaning and sanitizing methods. Three cleaning methods were evaluated (wiping, scrubbing, or no cleaning) alone or in combination with 200 ppm of bleach or 400 ppm of peracetic acid (either applied for 3 or 5 min) or no sanitizing. Regardless of cleaning method or contact time, peracetic acid reduced Salmonella on banana leaves to a level below the limit of quantification (<1.44 log CFU/cm2). The efficacy of sanitizing with bleach for banana leaves differed depending on the cleaning method (P = 0.044). Bleach applied for 5 min with wiping was most effective and reduced Salmonella on banana leaves to 2.85 log CFU/cm2 (95% confidence interval: 2.52, 3.18). For bamboo baskets, the most effective treatment was sanitizing with peracetic acid for 5 min regardless of cleaning method (P < 0.0001). This study offers insights for controlling Salmonella on food-contact surfaces commonly used in Cambodian fresh food markets. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the feasibility of blending passion fruit peel extract (PFPE) with polydopamine (PDA) solution and hydroxypropylmethylcellulose (HPMC) to prepare the properties of PFPE/PDA/HPMC composite films for their application in fruit and vegetable packaging. PFPE was extracted by ultrasonic‐assisted extraction method, which is simple, easy to operate and has high extraction efficiency, PFPE and dopamine were subjected to PFPE/PDA solution preparation, which in turn led to the preparation of HPMC, PFPE/PDA/HPMC films at different concentrations (0%, 5%, 10%, 15% and 20%), and 10% PDA/HPMC and PFPE/HPMC films were prepared with PDA and PFPE solutions, respectively. The interactions between the components in the films were analysed by infrared spectroscopy and X‐ray diffractometer, and the colour, mechanical properties, barrier properties and antioxidant activity of the films were determined. The results showed that the addition of PFPE/PDA solution had a positive effect on the performance of the films. The tensile strength of the composite films was 8.21 MPa, the elongation at break was 85.02% and the water vapour transmission was 2.62 × 10−14 g·mm/(cm2·h·Pa) when the content of PFPE/PDA was 20% compared to that of HPMC films; the DPPH radical scavenging rate and hydroxyl radical scavenging rate of the films increased with the increase of PFPE/PDA concentration, and the DPPH radical scavenging rate of the film with 20% additive was 28.71% and the hydroxyl radical scavenging rate was 34.77%, which were much higher than that of the HPMC film. The simulated bananas were stored at room temperature together with the films and stored at 25°C and tested every day, and it was found that the bananas without packaging film began to show browning on the third day, while the film with 20% additive still did not show obvious browning on the fifth day, so the addition of PFPE/PDA could effectively delay the browning of bananas and prolong their shelf life. In summary, this study improves the use value of passion fruit peel waste and provides new effective packaging for fresh bananas, while it can also provide a new way for the development of degradable films from plant extracts.

The global banana industry faces a significant threat from Fusarium oxysporum f. sp. cubense Tropical Race 4 (TR4). While prior research has concentrated on TR4's dissemination, reproductive conditions, and resistant banana varieties, this study employs a socioeconomic and cost-benefit analysis to explore the vulnerability of banana producers to TR4 in Colombia. It assesses the financial viability of current monitoring strategies and estimates potential losses in the event of TR4 spreading within the study area. Interviews were conducted with producers and key stakeholders in Colombia's top two banana-producing departments, Antioquia and Magdalena. The findings reveal that farming systems are highly vulnerable to TR4, particularly due to the prevalent use of corms. Producers employ preventive measures such as cement paths, fences, disinfecting stations, and footbaths to counteract TR4's spread. A cost-benefit analysis indicates that the benefits of these prevention methods significantly outweigh the associated costs, with a net present value of implementing prevention strategies per hectare of $95,389 USD and $112,527 USD in Magdalena and Antioquia and a benefit-cost ratio of 3.1 and 4.2, respectively. Considering the substantial impact TR4 could have in Colombia if it becomes more widespread, we recommend widespread adoption of preventive measures, including the construction and utilization of cement paths and disinfectant methods on all banana farms. Additionally, to enhance awareness and early detection, we propose leveraging technology, such as mobile applications (apps) and chat groups, to empower farmers in identifying and preventing the spread of TR4.

Calcium carbide is prohibited as a fruit ripening agent in many countries due to its harmful effects. Current methods for detecting calcium carbide in fruit involve time-consuming and destructive chemical analysis techniques, necessitating the need for non-destructive and rapid detection techniques. This study combined near infrared (NIR) spectroscopy with chemometrics to detect two banana varieties ripened with calcium carbide in different forms when they are peeled or unpeeled. Sixteen linear discriminant analysis (LDA) models were developed with high average classification accuracies for classifying banana based on the mode used to ripen banana, type of carbide treatment and the duration of soaking banana in carbide solution. Banana colour was predicted with partial least squared regression (PLSR) models with R
2 CV > 0.74, RMSECV and <5.4 and RPD close to 3. NIR coupled with chemometrics has good potential as a technique for detecting carbide ripened banana even if the banana is peeled or not. [ABSTRACT FROM AUTHOR]- Published

Divergent banana streak viruses (BSV) were characterized from banana plants exhibiting diverse symptoms in the Northeast region (NER) of India. Using rolling circle amplification (RCA), the complete genome sequences of seven episomal banana streak MY virus (BSMYV) isolates, including two novel variants, and two new banana streak IM virus (BSIMV) isolates were characterized. The novel BSMYV genetic variants were associated with conspicuous necrosis on newly emerged leaves, peduncle distortion, pseudostem internal necrosis, in addition to common streak symptoms. For complete genome nucleotide sequences, BSMYV-IN4 and IN5 shared 77–79% identity with other BSMYVs, while BSMYV-IN7 and IN8 exhibited identities of 77–97%. This study reports for the first time, the complete genomes of two banana streak IM virus (BSIMV-IN1 and -IN2) infecting triploid banana hybrids exhibiting leaf distortion, stunted rosette-like growth, and necrosis, sharing 87% sequence identity with reference BSIMV genome (GenBank accession no. HQ593112). Phylogenetic inference based on complete genomes revealed the distinct and congruent placement of BSMYV-IN4 and IN5 within the BSMYV cluster. Pairwise sequence comparisons of the conserved RT/RNase H nucleotide (nt) sequences revealed that the BSMYV-IN7 and IN4 isolates showed 85% and 97% identity to BSMYV (AY805074), respectively, which shared highest nt identity with BSMYV-IN6, IN9, and IN10, at 100%. The RT/RNase H nt sequences of BSIMV-IN1 and IN2 had 98% identity with the BSIMV (HQ593112), but were characterized as novel variants of BSIMV based on complete genomes. An analysis of relative synonymous codon usage (RSCU) pattern in the ORFIII polyprotein of BSMYV and BSIMV isolates revealed AGA and AGG (arginine) as the most frequently overrepresented codons (>1.5), evolutionary conserved in the genome of both species. A total of 14 recombination events were detected among the 36 BSV genomes, with recombination breakpoints mainly located in the ORFI, III, and IGR genomic regions. A novel phylogenetic cluster, comprised of BSMYV-IN4 and IN5 within the clade I was probably derived from heterologous recombination between parents resembling banana streak VN virus (BSVNV; AY750155) and banana streak GF virus (BSGFV; KJ013507) isolates. The present study conclusively reports the infection of genetically and symptomatically distinct variants of BSMYV and BSIMV infecting banana hybrids in NER India. [ABSTRACT FROM AUTHOR]

Cardiometabolic risk triggers a state of chronic and subclinical inflammation, conferring a higher risk of morbidity and mortality. Thus, minimal processing of foods with high nutritional value, in the form of flour, becomes an effective dietary strategy in preventing and treating cardiometabolic risk factors. This systematic review aims to evaluate the evidence on the effect of flour-based food intake on reducing the most common cardiometabolic risk factors. We included all randomized controlled trials published up to April 2023 in the main databases PubMed, Scopus and Web of Science. Eleven clinical trials were included. The amount of flour used in the studies ranged from 1.5 g to 36 g/day, and the supplementation period ranged from six weeks to 120 days. Green jackfruit flour, green banana flour, soy flour, flour from rind of the yellow passion fruit, and fenugreek powder demonstrated significant results in improve parameters of glucose homeostasis. Chia flour, green banana flour, soy flour, and fenugreek powder showed improvements in blood pressure measurements. Brazil nut flour and chia flour reduced total cholesterol. Chia flour also increased HDL cholesterol levels. The evidence presented in the current systematic review indicates that flour-derived foods intake is related to improve cardiometabolic risk factors parameters. [ABSTRACT FROM AUTHOR]

IRON oxide nanoparticles , *HUMAN DNA , *GENE therapy , *CYTOTOXINS , *TRANSMISSION electron microscopy , *BANANAS - Abstract
Magnet-mediated gene therapy has gained considerable interest from researchers as a novel alternative for treating genetic disorders, particularly through the use of superparamagnetic iron oxide nanoparticles (NPs)—such as magnetite NPs (Fe3O4NPs)—as non-viral genetic vectors. Despite their commercial availability for specific genetic transfection, such as in microglia cell lines, many potential uses remain unexplored. Still, ethical concerns surrounding the use of human DNA often impede genetic research. Hence, this study examined DNA-coated Fe3O4NPs (DNA-Fe₃O₄NPs) as potential transfection vectors for human foreskin fibroblasts (HFFs) and A549 (lung cancer) cell lines, using banana (Musa sp.) as a low-cost, and bioethically unproblematic DNA source. Following coprecipitation synthesis, DNA-Fe₃O₄NP characterization revealed a ζ-potential of 40.65 ± 4.10 mV, indicating good colloidal stability in aqueous media, as well as a superparamagnetic regime, evidenced by the absence of hysteresis in their magnetization curves. Successful DNA coating on the NPs was confirmed through infrared spectra and surface analysis results, while magnetite content was verified via characteristic X-ray diffraction peaks. Transmission electron microscopy (TEM) determined the average size of the DNA-Fe3O4NPs to be 14.69 ± 5.22 nm. TEM micrographs also showed no morphological changes in the DNA-Fe3O4NPs over a 30-day period. Confocal microscopy of HFF and A549 lung cancer cell lines incubated with fluoresceinamine-labeled DNA-Fe3O4NPs demonstrated their internalization into both the cytoplasm and nucleus. Neither uncoated Fe3O4NPs nor DNA-Fe3O4NPs showed cytotoxicity to A549 lung cancer cells at 1–50 μg/mL and 25–100 μg/mL, respectively, after 24 h. HFFs also maintained viability at 1–10 μg/mL for both NP types. In conclusion, DNA-Fe3O4NPs were successfully internalized into cells and exhibited no cytotoxicity in both healthy and cancerous cells across a range of concentrations. These NPs, capable of binding to various types of DNA and RNA, hold promise for applications in gene therapy. [ABSTRACT FROM AUTHOR]

The present work examines the relationship between aerial spraying and its health impacts on the population living in the banana production areas of Ecuador (the rural sectors of the cantons Milagro and Naranjito, Guayas Province). Objectives: the objectives of this study are to obtain information on sanitation, basic services, and environmental rationality and to interpret the low levels of cholinesterase and prevalent diseases among the population. Methods: the methodology involved a face-to-face questionnaire, the formal authorization of an informed consent document, and venipuncture for cholinesterase tests. The information was processed in the EPI–INFO system 7.2 (statistical software for professionals and researchers dedicated to public health), with the certification of protocols issued by the Bioethics Committee of the Kennedy Hospital Clinic of Ecuador. Results: the results showed that 89.5% of inhabitants do not have access to drinking water, 92.5% do not have a sewage disposal service, 97.50% experience aerial spraying at their homes or workplaces, and 57% have low cholinesterase levels. Additionally, several gastrointestinal, respiratory, neurological, dermatological, and reproductive disorders were detected among the inhabitants. Conclusions: we found that companies in the banana sector have not implemented corporate social responsibility measures. For example, no blood tests are conducted to monitor cholinesterase levels or to track hereditary disorders. Moreover, entities such as the Ministry of Public Health have not taken action to serve this at-risk population. [ABSTRACT FROM AUTHOR]

Banana fruits are rich in starch, and unripe banana flour is considered a beneficial ingredient in the food industry because it has high levels of resistant starch, which significantly aids in promoting gut health and regulating blood sugar and lipid levels. However, the associations between banana cultivars with various genotypes cultivated globally and their resistant starch properties remain unclear. Herein, we investigated resistant starches from 16 banana cultivars covering three genome groups (ABB, AAB, and AAA) in order to reveal the differences and similarities among these cultivars. The results showed that there was a genotype-specific pattern in banana resistant starch (BRS) degradation. The AAA genome BRS exhibited a high degree of resistant starch degradation. The genotypes of the banana cultivars also impacted the granular morphology of the resistant starch. The ABB and AAB genome BRS were more conducive to forming resistant starch. The BRS samples from the three genome groups displayed either B-type or C-type structures. Even within the same genome group, the BRS samples exhibited differences in thermal and pasting properties. These findings reveal the impact of genotypes on BRS content and characteristics, providing a basis for future breeding and resistant starch utilization. [ABSTRACT FROM AUTHOR]

Societal Impact Statement Summary Bananas are nutritious fruits of major importance worldwide. Characterizing their diversity is essential to ensure their conservation and use. A catalog showcasing cultivated bananas genomic diversity was compiled and is to be used as a tool to support the classification of banana cultivars. This research revealed that cultivated banana groups are not all made of identical clones. Materials from recent collecting missions indicated that more banana diversity is expected to be found as the exploration of the banana gene pool continues. These discoveries will drive dynamic conservation strategies for banana genetic resources and should increase their use. Banana is an important food crop cultivated in many tropical and subtropical regions around the world. Because banana cultivars often have low fertility, they are typically propagated clonally, which maintains desirable traits across generations. However, different factors, such as synonymy, incomplete passport data, and environmental effects, complicate the morphological‐based assignment of banana cultivars to specific clones or cultivar groups. In this study, we applied a previously developed genomic‐based tool for fine‐scale characterization of banana ancestry, known as in silico chromosome painting, to high‐throughput genotyping data from 317 banana accessions. This dataset covers most of the globally conserved, studied, and cultivated cultivar groups and includes both genebanks and new, uncharacterized materials. By comparing curated morphological assignation to the genomic patterns resulting from in silico chromosome painting, we compiled a diversity catalog referencing curated passport data, pictures, and chromosome painting patterns of the cultivar groups. Examining the genomic patterns obtained, intra‐cultivar group variability was discovered. In some cultivar groups, mitotic recombination or deletions accumulated clonally. In addition, at least four cultivar groups encompassed cultivars from distinct sexual events co‐existing, notably Pisang Awak with five distinct patterns across two ploidy levels. Finally, additional patterns were discovered in the newest materials of the set, showing that a wider diversity of clones still exists

X-Ray micro-computed tomography (XCT) is used to reveal the micro-structural changes of banana pseudostem nanocellulose bioplastic due to a biodegradation process initiated in a formulated composting media that allowed the growth of aerobic microflora. The bioplastic itself was made of nanocellulose, which was isolated from banana pseudostem using the 2,2,6,6-Tetramethyl-1-piperidinyloxy (TEMPO) mediated oxidation method, and polyethylene glycol (PEG) as plasticiser. XCT provided insights into the 3D structural change of the bioplastic identifying the degradation process at two scales. The results showed that the local thickness and roughness of the bioplastic increased after degradation, while the density of the material decreased. Enlarged voids and tunnels were observed in the material after degradation. The formation of these tunnels is attributed to the popping of internal PEG-containing voids because of the generation of gases, which after forming may further accelerate biodegradation by microbial activity.

Biomass pretreatment is essential to facilitate lignin removal and enhance cellulose concentration for optimal bioethanol production. Therefore, this research aimed to determine the effects of conventional KOH (KP) and Combined KOH microwave-assisted (CKMP) pretreatment on the banana stem (BS) composition, analyzing the kinetics of lignin removal at various temperatures and KOH concentrations for 25 min. Kinetics variables were calculated by fitting experimental data and cellulose was hydrolyzed to produce reducing sugars. The results showed that the highest lignin removal for KP and CKMP were 37.11%, and 40.39%, respectively, with CKMP having the lowest activation energy of approximately 2.688 kJ mol−1. CMCase and FPase activity were 1988.3474 and 1605.4187 U mL−1, respectively, which were significantly higher than the values reported in previous research. The maximum concentration of reducing sugars achieved was 17.69 g L-1, with an enzyme concentration of 50% (v/w), pH 5, and a hydrolysis duration of 25 h. Michaelis constant varied from 0.0037 to 0.0079, and the maximal rate ranged from 1.28 × 10−6 to 2.76 × 10−6 Mol L−1 s−1 when computing the reaction rate using the Michaelis–Menten kinetics model. [Display omitted] • The results of this study provided insight into producing bioethanol from banana stems. • Combined KOH microwave-assisted pretreatment (CKMP) of banana stem was carried out. • Lignin content was effectively removed at 43.02%. • Enzymatic hydrolysis kinetics followed the Michaelis–Menten kinetics model. • K M value was 0.0037–0.0079 and v max was 1.28 × 10−6 to 2.76 × 10−6 Mol L−1 s−1.

Introduction: Fusarium wilt, caused by Fusarium oxysporum f. sp. cubense (Foc), poses a significant global threat to banana cultivation. Conventional methods of disease management are increasingly challenged, thus making it necessary to explore alternative strategies. Bacterial endophytes, particularly from resistant genotypes, are gaining attention as potential biocontrol agents. Sphingobacterium thalpophilum, isolated from the resistant banana cultivar Pisang lilin (JALHSB010000001-JALHSB010000029), presents an intriguing prospect for combating Fusarium wilt. However, its underlying biocontrol mechanisms remain poorly understood. This study aimed to elucidate the antifungal efficacy of S. thalpophilum NMS02 S296 against Foc and explore its biocontrol mechanisms at the genomic level. Methods: Whole genome sequencing of S. thalpophilum NMS02 S296 was conducted using next-generation sequencing technologies and bioinformatics analyses were performed to identify genes associated with antifungal properties. In vitro assays were used to assess the inhibitory effects of the bacterial isolate on the mycelial growth of Foc. To explore the biomolecules responsible for the observed antagonistic activity, metabolites diffused into the agar at the zone of inhibition between Foc S16 and S. thalpophilum NMS02 S296 were extracted and identified. Results: Whole genome sequencing revealed an array of genes encoding antifungal enzymes and secondary metabolites in S. thalpophilum NMS02 S296. In vitro experiments demonstrated significant inhibition of Foc mycelial growth by the bacterial endophyte. Comparative genomic analysis highlighted unique genomic features in S. thalpophilum linked to its biocontrol potential, setting it apart from other bacterial species. Discussion: The study underscores the remarkable antifungal efficacy of S. thalpophilum NMS02 S296 against Fusarium wilt. The genetic basis for its biocontrol potential was elucidated through whole genome sequencing, shedding light on the mechanisms behind its antifungal activity. This study advanced our understanding of bacterial endophytes as biocontrol agents and offers a promising avenue for plant growth promotion towards sustainable strategies to mitigate Fusarium wilt in banana cultivation.

Early diagnosis has a pivotal role in the effective control and prevention of disease in fruit crops. Loop‐mediated isothermal amplification (LAMP) has emerged as a prominent modality for disease diagnosis owing to its rapid detection, heightened sensitivity, exceptional specificity and easy operational procedures. The advent of LAMP‐coupled CRISPR‐Cas12, multiplex LAMP (mLAMP) and digital LAMP (dLAMP) has contributed to a paradigm shift in the field and increased the applicability of LAMP technology in viral disease detection. Such advancements have further extended the reach and efficacy of LAMP methodologies in diagnostic research. Here, we review LAMP detection technology application to identify viral diseases in fruits (e.g., apple, passion fruit, banana and citrus) and summarize current developments in LAMP technology and its future prospects, which could enhance its application in the detection of fruit viral diseases.

Background: The projection of prana to soil, seeds and seedlings to enhance plant growth is referred to as Pranic Agriculture (PA). Methods: A field study was carried out to study the influence of PA on Banana var. (Musa sps. var. Nanjangud rasabale) growth for a duration of one year. Banana suckers and agricultural land were divided into two groups namely pranic and control in half acre. The land and suckers were treated with PA and were referred to as the pranic group, while non-pranic were referred to as the control group. Growth parameters (shoot length, shoot diameter, number of leaves, leaf length and leaf diameter) were evaluated on the 2nd, 4th, 6th, 8th, 10th and 12th months and statistically analyzed using repeated measure ANOVA. Fruit morphology and days to flowering were analyzed using a t-test. Result: For pranic group, shoot diameter (F= 9.407, p= 0.001), leaf length (F= 7.082, p= 0.003) and leaf diameter (F= 11.459, p= .000), flowering days (t= 3.39, P=.002), fruit characteristics like fruit bunch weight (t= 8.81, p= .000), total number of fruits in bunch (t= 9.20, p= .000), fruits weight (t= 7.48, p= .000), fruit length (t= 7.94, p= .000) enhanced considerably and the results were all significant when compared to control. Further studies are needed to find out the mechanism for the improved growth in the pranic group. This study will help the farmers to get higher yields and more income by using pranic agriculture.

Summary: Transcriptional regulation mechanisms underlying chilling injury (CI) development have been widely investigated in model plants and cold‐sensitive fruits, such as banana (Musa acuminata). However, unlike the well‐known NAC and WRKY transcription factors (TFs), the function and deciphering mechanism of heat shock factors (HSFs) involving in cold response are still fragmented. Here, we showed that hot water treatment (HWT) alleviated CI in harvested banana fruits accomplishing with reduced reactive oxygen species (ROS) accumulation and increased antioxidant enzyme activities. A cold‐inducible but HWT‐inhibited HSF, MaHsf24, was identified. Using DNA affinity purification sequencing (DAP‐seq) combined with RNA‐seq analyses, we found three heat shock protein (HSP) genes (MaHSP23.6, MaHSP70‐1.1 and MaHSP70‐1.2) and three antioxidant enzyme genes (MaAPX1, MaMDAR4 and MaGSTZ1) were the potential targets of MaHsf24. Subsequent electrophoretic mobility shift assay (EMSA), chromatin immunoprecipitation coupled with quantitative PCR (ChIP‐qPCR) and dual‐luciferase reporter (DLR) analyses demonstrated that MaHsf24 repressed the transcription of these six targets via directly binding to their promoters. Moreover, stably overexpressing MaHsf24 in tomatoes increased cold sensitivity by suppressing the expressions of HSPs and antioxidant enzyme genes, while HWT could recover cold tolerance, maintaining higher levels of HSPs and antioxidant enzyme genes, and activities of antioxidant enzymes. In contrast, transiently silencing MaHsf24 by virus‐induced gene silencing (VIGS) in banana peels conferred cold resistance with the upregulation of MaHSPs and antioxidant enzyme genes. Collectively, our findings support the negative role of MaHsf24 in cold tolerance, and unravel a novel regulatory network controlling bananas CI occurrence, concerning MaHsf24‐exerted inhibition of MaHSPs and antioxidant enzyme genes.

The hydrothermal synthesis of CuO/NiO composites was conducted using banana fruit biomass waste. In this study, X-ray powder diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy were used to investigate the crystalline properties, shape structure, and functional group characterization of CuO/NiO composites. The typical morphology of the prepared materials consisted of irregular nanoparticles arranged into clusters of less than 200 nanometers in size. In spite of this, the CuO/NiO composites showed monoclinic CuO and cubic NiO phases and were therefore successfully synthesized. It was observed that rotten banana fruit juice had a significant impact on the particle size and crystal quality of CuO/NiO composites. This was due to the presence of capping, reducing, and stabilizing agents in banana fruit juice. Under alkaline conditions, the CuO/NiO composites were found to be highly electro catalytically active toward the oxidation of urea. Sample 2, which was prepared by adding 1.2 g of CuO decorated with NiO, showed a linear increase in urea detection ranging from 0.1 mM to 17 mM, with a limit of detection of 0.004 mM. Furthermore, sample 2 of the CuO/NiO composite demonstrated exceptional stability, selectivity, and reproducibility. Consequently, sample 2 of CuO/NiO could effectively detect urea in spinach, lotus root, milk, and curd. The improved performance of sample 2 of the CuO/NiO composite can be attributed to its favorable surface properties, which contain enriched active sites and a rapid charge transfer rate.
