In the spring of 2022, botanical surveys carried out in the Belezma National Park allowed the rediscovery of Tulipa sylvestris subsp. primulina, a rare and endemic Algerian-Moroccan species. The provided photographs as well as an accurate description of the plant facilitate its identification. The added map shows its distribution throughout Algeria. [ABSTRACT FROM AUTHOR]

To investigate the cold response mechanism and low temperature regulation of flowering in tulips, this study identified 32 MADS-box transcription factor family members in tulips based on full-length transcriptome sequencing, named TgMADS1-TgMADS32. Phylogenetic analysis revealed that these genes can be divided into two classes: type I and type II. Structural analysis showed that TgMADS genes from different subfamilies have a similar distribution of conserved motifs. Quantitative real-time PCR results demonstrated that some TgMADS genes (e.g., TgMADS3, TgMADS15, TgMADS16, and TgMADS19) were significantly upregulated in buds and stems under cold conditions, implying their potential involvement in the cold response of tulips. In summary, this study systematically identified MADS family members in tulips and elucidated their evolutionary relationships, gene structures, and cold-responsive expression patterns, laying the foundation for further elucidating the roles of these transcription factors in flowering and the cold adaptability of tulips.

Amana, commonly known as 'East Asian tulips', has recently been found to harbor cryptic diversity due to recent field work and systematic investigations. In this study, we included 64 populations from all 12 Amana species and performed microscopic observations of their epidermal morphology. The leaf epidermis stomatal distribution of Amana can be characterized into three types: dense stomata (>10/per view or 263/mm2), sparse stomata (<10/per view or 263/mm2), and stomata absent. The epidermal cells of Amana can be characterized into four types: rectangular, long rectangular, nearly rectangular, and rhombic. The anticlinal wall morphology of the epidermal cells can be characterized into three types: linear, wavy, and nearly linear with mixed shallow waves. All the results were helpful for classification of Amana species. According to the reconstruction of ancestral characters analyses, the common ancestor of Amana is most likely to have leaves with dense stomata on both sides, and epidermal cells that have linear vertical walls.

Aiming at evaluating new candidate species for the cut flower market of Greece and beyond, in this study, the vase life of three Greek tulip plant species, Tulipa cretica 'Hilde' (CRH, local endemic of Crete, Greece), T. clusiana 'Chrysantha' (CLC, naturalized in Chios Island, Greece), and T. australis (AUS, native in the Mediterranean and Greece), was investigated in comparison to the commercial tulip hybrid Île-de-France (IDF). To this end, pre-cooled at 4 °C bulbs of the abovementioned Greek tulip plant species were bought from Dutch nurseries and grown in pots placed in unheated greenhouses located at two different climatic conditions in Northern Greece. The plants were uprooted when the flowers reached a slightly open stage. Half of the flowering stems were immediately placed into bottles with deionized water, while the rest were placed in a preservative solution containing citric acid 5% and sulfuric acid 1% and then remained under laboratory conditions until the entire tepal wilted (end of vase life). The measurements performed concerned: (a) flower stem length and flower maximum diameter, (b) fresh weight (FW) of initial stems, leaves, flowers, and bulbs and at the end of vase life, (c) flower color parameters (L, a, b, c, and H) in all treated flowers, (d) leaf chlorophyll content (SPAD values), and (e) initial and final water volume after removing the flowering stems. The aforementioned measurements showed that CRH cut flowers may exhibit consistent floral opening patterns and were associated with a long mean vase life of 5.7 days, which can be further prolonged to 6.5 days by carefully selecting a cultivation location with proper climatic conditions. The vase life of CLC cut flowers was significantly affected by the climatic parameters (temperature) of the area where the plants were cultivated. The immersion of cut flowering stems in a preservative solution with citric and sulfuric acids did not yield a notable increase in the longevity of cut flowers during the postharvest period. Moreover, this treatment did not have any significant impact on leaf chlorophyll content or flower color at the end of the flowers' vase life. The data of this work show that cut flowers from the native species T. cretica and T. clusiana have satisfactory vase life, especially when plants were grown in favorable climate condition; the latter is an important criterion for their entry into the cut flower market.

The tulip is an important cut flower around the globe. The Tulip is not famous in Pakistan for sale and cultivation for commercial purposes as well. The evaluation of exotic varieties are very important for recommendation to local farmers for better yield. Four tulip varieties cv. Antarctica, Oxford, Ballerina and Apeldoorn were purchased for evaluation. The 100 bulbs of each variety were planted in the bed. The performance of the plants during 2017-18 were judged by observing the bulb germination percentage, leaf width (cm), leaf length (cm), scape length (cm), flower size (mm), primary color of the flower, secondary color of flower, no. of large, medium and small size of bulbs and number of bulbs harvested. The bulbs were harvested and stored at 5±2oC (In Refrigerator). The morphological attributes of plants were observed better in cv. Antarctica and Oxford. The research was repeated during the subsequent years. The variable response was observed in various varieties of tulip in Rawalpindi climate. The cv. Antarctica and Oxford were observed as best performer wise all the attributes. The same varieties are recommended to local farmers for cultivation as well. [ABSTRACT FROM AUTHOR]

Tulip growth involves a warm–cold–warm cycle and this work addresses the possibility of carrying out the final warm step of this cycle during the winter months of a subtropical country where electric power has a low price — Paraguay. This is a result of an abundance of renewable energy resources mainly due to the presence of two large hydroelectric power plants. This final cultivation step requires temperatures between 16 °C and 20 °C during a period of about five months. Historic climate data suggest that the city of Encarnación is suitable for tulip cultivation in Paraguay. However, because of temperature fluctuations, air conditioning may occasionally be necessary for cooling or heating. Using a transient model, we simulate the thermal conditions of the nursery to find the energy needed for air conditioning. Good thermal insulation and injection of external ambient air to control the nursery’s temperature whenever possible reduce the use of electrical energy.

The floral coloration of tulip flowers is one of the most prominent traits contributing to its high ornamental value. The molecular mechanisms of petal coloration remain elusive in tulip species. In this study, we performed comparative metabolome and transcriptome analyses using four tulip cultivars with distinguished petal colors. Four types of anthocyanins were identified, including cyanidin derivatives and pelargonidin derivatives. Comparative transcriptome analysis identified 22,303 differential expressed genes (DEGs) from the four cultivars, and 2589 DEGs were commonly regulated in three comparison groups (colored vs. white cultivar), including anthocyanins biosynthesis‐related genes and regulatory transcription factors. Two basic helix–loop–helix (bHLH) transcription factors, TgbHLH42‐1 and TgbHLH42‐2, with differential expression levels among cultivars and petal developmental stages, have high homology to TRANSPARENT TESTA 8 (AtTT8) of Arabidopsis. The anthocyanins accumulation in TgbHLH42‐1 overexpressing (OE) seedlings was markedly greater than that in wild‐type seedlings in the presence of methyl jasmonate (MeJA), but not for TgbHLH42‐2 OE seedlings. Both TgbHLH42‐1 and TgbHLH42‐2 restored pigmentation defects in tt8 mutant seeds after complementation assay. TgbHLH42‐1 could interact with MYB protein AtPAP1 to synergistically activate the transcription of AtDFR, whereas TgbHLH42‐2 failed to. Silencing TgbHLH42‐1 or TgbHLH42‐2 individually could not, but simultaneously silencing both TgbHLH42 could reduce the anthocyanin in tulip petals. These results indicate that TgbHLH42‐1 and TgbHLH42‐2 function partially redundantly to positively regulate anthocyanin biosynthesis during tulip petal coloration. [ABSTRACT FROM AUTHOR]

A new species of True Tulip Shell in the genus Fasciolaria has been discovered in lobster traps set in deep water off the Dry Tortugas, western Florida Keys. This new TulipShell is closest to the widespread Carolinian Province-Caribbean Province F. tulipa (Linnaeus, 1758) but differs in having a proportionally shorter siphonal canal, in having a conspicuous stripedcolorpattern and stronger raised cords on the siphonal canal, and by having sharply-angled spire whorls that bear prominent rounded knobs on the first post nuclear whorls. In this aspect, the coronated post nuclear whorls of the new species, here named F. bittneri, resemble those seen on the heavily-ornamented Calabrian Pleistocene species, F. okeechobeensis Tucker & Wilson, 1932, from the Bermont Formation of southern Florida.

Due to botanical tulips' economic interest coupled with limited information regarding their seed germination, we investigated the effect of temperature on dormancy release and germination in two endangered local endemic tulip species of Greece (Tulipa hageri Heldr., T. orphanidea Heldr.). Their germination responses at five constant temperatures (5, 10, 15, 20, and 25 °C) were evaluated in growth chambers, while the type of seed dormancy and the temperature effect on its release were determined based on open-sourced, R-derived species-specific ecological profiles illustrating abiotic conditions of their wild habitats. The results indicated a range-specific temperature dependence in seed germination for both studied species with seed germination observed only in very low temperatures (5–10 °C). The seeds of both species after dispersal had an underdeveloped embryo. The existence of a complex morphophysiological seed dormancy was confirmed in both species by the significant embryo development only at 5 and 10 °C (almost doubled after 30 days) coupled with observed delay in germination only at low temperatures. Furthermore, to facilitate their cultivation and ex situ conservation, the germinated seeds were planted in pots to develop bulblets in greenhouse conditions resulting in bigger T. orphanidea bulblets compared to T. hageri.

Understanding the effects of environmental parameters on the reproductive cycle of shellfish is an essential tool for successful hatchery conditioning management and, consequently, for seed supply to the industry. For the tropical oyster, Crassostrea tulipa, little is known about the factors affecting the maturation process and reproduction, but there are indications that salinity may be of importance. Two experiments were carried out to evaluate the effects of salinity on the reproductive cycle of broodstock of C. tulipa. In the first experiment, oysters were reared in five salinities (40, 35, 30, 25, and 20) for 40 days and gonad histological samples were collected regularly. In a follow up experiment, oysters were reared in variable salinity conditions changing from 40 to 30 or from 20 to 30 over a period of 40 days. Salinity was found to affect the reproductive cycle of C. tulipa. Oysters kept in constant salinity of 30 showed a higher condition index compared to animals in other salinities, with most of the animals in the prespawning stage. Salinity variation was also shown to affect C. tulipa maturation. The prespawning stage was the most observed reproductive stage in low salinity, and high salinity induced a resting stage in the female animals. The results are considered the first step towards developing a protocol for the conditioning of C. tulipa in hatchery conditions. [ABSTRACT FROM AUTHOR]

Simple Summary: Greek wild-growing tulips are protected plants, about which there is scarce knowledge regarding their natural nutrient status and rhizosphere fungal morphotypes. In this study, we collected plant (above-ground and bulb material) and soil samples from 13 tulip species across three phytogeographical units in Greece, and we assessed the tulips' nutrient content and soil properties to determine their interrelationships. We found that soil variables significantly influenced tulip nutrient content, with up to 67% of the detected variability explained by soil properties. Correlation patterns were also found between tulips' essential nutrients. Our study revealed clear distinctions in nutrient content among tulip species from different spatial (phytogeographic) units. The findings shed light on Greek tulips' adaptability and resilience in their natural habitats and may facilitate their domestication in artificial settings. Wild-growing Greek tulips are protected plants but almost nothing is known about their natural nutrient status and rhizosphere fungal morphotypes in the wild, thus no insight is currently available into their growth and adaptation to their natural environment or artificial settings. To this end, several botanical expeditions were conducted with a special collection permit, and 34 tulip and soil samples were collected, representing 13 species from two phytogeographical regions of Greece (North Aegean Islands, Crete Island) and seven regions of mainland Greece. The tulips' content in essential macro- and micro-nutrients, respective physicochemical soil properties, and rhizosphere fungal morphotypes were assessed across samples, and all parameters were subjected to appropriate statistical analysis to determine their interrelationships. The results showed that soil variables played a significant role in shaping tulips' nutrient content, explaining up to 67% of the detected variability as in the case of phosphorus (P) in the above-ground plant tissue. In addition, significant correlations were observed (with an r value of up to 0.65, p < 0.001) between essential nutrients in the tulips, such as calcium (Ca) and boron (B). The principal component analysis (PCA) revealed that between the three spatial units examined, the total variability of tulips' nutrient content produced a clear distinction among sampled species, while the first two PCA axes managed to explain 44.3% of it. This was further confirmed by the analysis of variance (ANOVA) results which showed corresponding significant differences (at p < 0.05) in both the tulips' nutrient content and the studied soil properties as well (mean values of N, P, and K in the North Aegean Islands tulips' nutrient content, up to 53%, 119%, and 54% higher compared to those of the Crete Island, respectively). Our study sheds light on Greek tulips' adaptability and resilience in their original habitats, facilitating at the same time the undertaken efforts regarding their conservation and potential domestication in artificial settings.

Although tulips are famous worldwide as ornamental plants, the knowledge about the seed germination of wild-growing species remains limited. The aim of the present study was to investigate the effect of temperature on seed germination of the local, wild-growing Greek endemics Tulipa bakeri and T. goulimyi and the sub-Balkan endemic T. undulatifolia, which are threatened with extinction, as well as the Mediterranean T. australis and the Asiatic T. clusiana naturalized on Chios Island (Greece). The germination responses at five constant temperatures (5, 10, 15, 20, and 25 °C) were assessed for all studied species in growth chambers under a 12:12 light–dark photoperiod. The ecological profile for each species was developed in R using open-source bioclimatic data; this was built to illustrate the abiotic environmental conditions of their wild habitats, to facilitate the examination of temperature effects on seed germination, and to facilitate their cultivation in artificial environments. The results indicated that the seed germination requirements of the studied species had a range-specific temperature dependence, reflecting their natural adaptation to local ecological conditions. Seed germination of T. bakeri, T. australis, and T. clusiana was observed only in a narrow range of very low temperatures (5–10 °C), whereas germination of T. undulatifolia and T. goulimyi occurred at temperatures between 5 and 15 °C. A temperature increase to 20 or 25 °C resulted in the absence of seed germination for all five Greek tulip species. The germinated seeds were planted in pots and bulblets were developed under greenhouse conditions. Seeds and bulblets constitute valuable genetic materials for the cultivation and ex situ conservation of these five Greek tulip species, three of which are threatened with extinction.

The use of inducers of systemic acquired resistance (SAR) is widely described in the literature. Such substances have important advantages over plant protection products (PPPs) and, thus, are often indicated as their alternatives. The main risk indicated in the context of the widespread use of SAR inducers is that of yield reduction that may result from the excessive metabolic imbalance of the treated plant. The general aim of the study presented was to check the effect of using a new active substance, namely N-methoxy-N-methylbenzo(1.2.3)thiadiazole-7-carboxamide (BTHWA), on tulips cultivated in greenhouse conditions. The plant response to BTHWA treatment was also analyzed in terms of the extent to which the growth–immunity phenomena would occur. Surprisingly, the application of BTHWA provided not only efficient protection against fusariosis but also resulted in the stimulation of the growth and development of tomato plants. The results proved very interesting as they stand in contrast to other results on SAR induction. The method of BTHWA application used in this study resulted in SAR induction at a level sufficient to provide effective protection and, at the same time, did not cause disruption to plant metabolism that would result in yield reduction.

Tulip bulb production is limited under drought stress conditions. Due to nutrient limitations, the growth rate is significantly reduced. Attention needs to be given to the plant-related microbiome because it can help the plant cope with stressful situations. A three-factor experiment (cultivar, SB fertilizer, and drought stress) was set up to study tulip bulb characteristics. Drought stress at three levels (90, 80, and 70% of field capacity, FC), SB fertilizer at four levels (control, PSB, KSB, and PSB+KSB), and two cultivars (ʻGolden Melodyʼ and ʻApeldoornʼ) were applied. The application of PSB+KSB significantly increased the nutrient concentration (N, P, and K) in different parts of tulips, including the root, bulblet, outer and inner scale, under drought stress. The bulblet of ʻGolden Melodyʼ accumulated more K and P than ʻApeldoornʼ under drought conditions. Water-soluble sugar accumulation was maximum to a minimum depending on the outer scale ˃ bulblet ˃ inner scale. Application of PSB and KSB with irrigation water reduced the adverse effects of drought stress on water-soluble sugars, anhe combined treatment of PSB+KSB resulted in the highest amount of water-soluble sugars in a tulip, indicating a synergistic effect of PSB and KSB on tulip bulbs. The highest leaf number and leaf area were observed at 90% FC when PSB+KSB was applied. Drought stress reduced the number, diameter, and weight of bulbs, while application of PSB+KSB resulted in the highest diameter (47.7 mm), and weight (45.3 g) of cultivar ʻGolden Melodyʼ. Application of PSB+KSB fertilizer over irrigation water promoted bulb production of tulip cultivars under drought stress. [ABSTRACT FROM AUTHOR]

The aim of this study was to check the effects of sugar type on the in vitro shoot multiplication of the tulip cultivar 'Heart of Warsaw' and the effects of paclobutrazol (PBZ) and 1-naphthylacetic acid (NAA) on the bulbing of previously multiplied shoots. In addition, the subsequent effects of previously used sugars on the in vitro bulb formation of this cultivar were checked. First, the optimum supplementation of Murashige and Skoog medium with plant growth regulators (PGRs) was selected for shoot multiplication. Of the six tested, the best results were obtained using a combination of 2iP 0.1 mg·L−1, NAA 0.1 mg·L−1, and mT 5.0 mg·L−1. The effects of different carbohydrates (sucrose, glucose, and fructose at 30 g·L−1 and a mixture of glucose and fructose at 15 g·L−1 each) on multiplication efficiency was then tested on this medium. The microbulb-forming experiment was carried out taking into consideration the effects of previously applied sugars, and at week 6, the agar medium was flooded with liquid medium containing NAA 2 mg·L−1, PBZ 1 mg·L−1, or medium without PGRs; in the first combination, the cultures were left on a single-phase medium, solidified with agar, as a control. After 2 months of treatment at 5 °C, the total number of microbulbs formed and the number and weights of mature microbulbs were assessed. The results obtained indicate the ability of using meta-topolin (mT) in tulip micropropagation and point to sucrose and glucose as the optimal carbohydrates for intensive shoot multiplication. The results lead to the conclusion that it is most advantageous to multiply tulip shoots on glucose medium and then to carry out cultures on a two-phase medium with PBZ, which results in a higher number of microbulbs and their faster maturation.

The poem "Divided" by Puneet Dutt reflects on themes of division and change through the metaphor of lilacs and family relationships. The speaker contemplates the fleeting nature of beauty and the passage of time, using vivid imagery to convey emotions of loss and resilience. Dutt's work invites readers to reflect on the complexities of life and the importance of balancing different aspects of our existence. [Extracted from the article]

In this study, the dynamic behavior of the premixed syngas/air flames in enclosed ducts with obstacles at the blockage ratio of 0.5, as well as without obstacles, was studied via large eddy simulation and the turbulent flame speed closure model. The hydrogen volume fraction (hydrogen content in fuel) was set to 50 %. Results indicate that the simulation reproduced the flame shapes, flame speed and explosion overpressure observed in the experiments. In cases without obstacles, a "tulip" flame with a tulip cusp can be seen, and secondary cusps emerge on tulip lips due to the high-pressure zone ahead of "tulip" flame lips, leading to in a distorted "tulip" flame. In cases with obstacles, the flame develops hemispherical and finger shapes upstream of the obstacles and evolves into a "tulip" flame downstream of the obstacles due to vortices and adverse pressure gradients. The alteration of the flow direction within the unburned and burned zones results in intricate flame shapes. Flame speed and overpressure show a close relationship and exhibit oscillations following the generation of the "tulip" flame. Typically, the velocity, pressure and flow fields adjacent to the flame front can affect dynamic behaviors of premixed syngas/air flames. [ABSTRACT FROM AUTHOR]

Seeds are important for the preservation and reproduction of wild tulips in situ, but only a few studies have been carried out on their seed morphology and germination characteristics. In this study, the eight wild tulip species native to China were used. Their seed morphology and superficial ornamentation, the relationship between seed morphology and germination, and the effects of manipulating incubation temperature, seed coat, and gibberellin (GA3) application were studied. The seeds are diverse in shape, size, color, weight, and superficial ornamentation, as observed by stereomicroscopy and scanning electron microscopy. Tulipa edulis (Miq.) Baker had a half-moon-shaped seed with the embryo invisible and irregular striped ornamentation, which was different from the other seven species that had sector-shaped seeds with the embryo visible and irregular reticulate ornamentation. Especially, the muri feature and the decorative pattern in meshes were highly variable and decisive at both section and species levels of Tulipa L. We also classified the seed dormancy type of the eight wild tulip species as nondeep complex (MPD). Embryo length, embryo/seed length ratio, and seed coat color were correlated with germination (T50), while the T50 of eight wild tulip species was still mainly affected by optimized temperatures of 4 °C and/or 4/16 °C. Gibberellin (GA3) has a positive regulating effect on the T50 of tulip species, and 100 μM gibberellin was considered the most effective concentration. These results highlight the taxonomic significance of the genus Tulipa based on seed testa morphology, and we support the notion that T. edulis should be regarded as an independent genus—Amana. Meanwhile, our study provided a way that the seed germination of wild tulip species could be shortened within 2 months under the experimental conditions, which will help to rapidly multiply and utilize wild tulip resources.

Neuropsychological assessment of culturally diverse populations is hindered by barriers in language, culture, education, and a lack of suitable tests. Furthermore, individuals from diverse backgrounds are often unfamiliar with being cognitively tested. The aim of this study was to develop a new neuropsychological test battery and study its feasibility in multicultural memory clinics. Composition of the TULIPA battery (Towards a Universal Language: Intervention and Psychodiagnostic Assessment) entailed a literature review and consultation with experts and individuals from diverse backgrounds. Feasibility was investigated by examining administration and completion rates and the frequency of factors complicating neuropsychological assessment in 345 patients from 37 countries visiting four multicultural memory clinics in the Netherlands. The test battery included existing tests such as the Cross-Cultural Dementia screening (CCD), Rowland Universal Dementia Assessment Scale (RUDAS), tests from the European Cross-Cultural Neuropsychological Test Battery, and newly developed tests. Completion rates for the test battery were generally high (82%–100%), except for CCD Dots subtest B (58%). Although tests of the "core" TULIPA battery were administered often (median: 6 of 7, IQR: 5–7), supplementary tests were administered less frequently (median: 1 of 9; IQR: 0–3). The number of administered tests correlated with disease severity (RUDAS, ρ=.33, adjusted p <.001), but not with other patient characteristics. Complicating factors were observed frequently, e.g. suboptimal effort (29%–50%), fatigue (29%), depression (37%–57%). The TULIPA test battery is a promising new battery to assess culturally diverse populations in a feasible way, provided that complicating factors are taken into account.

Corms of a mixed cultivars of Anemone coronaria ('Mr. Fokker', 'Sylphide', 'Hollandia', 'The Bride', 'Harmony White') were planted in raised beds during the fall, winter and spring. Without applying any maintenance except weed control, plants from the corms planted in November had the most flowers and managed to survive best during the two years of observations. Anemones planted in February and March were able to flower in June and July, when the air temperature was over 30°C. In conclusion, Anemone coronaria proved to be an excellent species for spring conditions in Bucharest, with an extended flowering period, much more than other species such as tulips, daffodils or hyacinths. Moreover, regardless of the planting date, anemone plants are suitable for sustainable flower plantations. [ABSTRACT FROM AUTHOR]

Abstract—The floristic complexes of the Vetlyanka River are characterized by a high pool of rare plants with various protection categories in the Saratov region. In total, the complexes include six species: Bulbocodium versicolor, Hyacinthella leucophaea, Tulipa gesneriana, Iris pumila, I. halophila, and Scilla siberica. These ecotopes have been recorded for the first time for S. siberica, B. versicolor, and Iris halophila. At the same time, S. siberica and I. halophila have a narrow ecological range. The studied cenopopulations of rare plants in the floristic complexes of the Vetlyanka River are stable in time and space. There is a self-renewal process in cenopopulations of the studied plants, which is hampered by a number of anthropogenic factors. The ontogenetic spectrum of the B. versicolor cenopopulation is a single-vertex spectrum with a high proportion of individuals of the generative fraction (70.2%). The age spectrum of the S. siberica cenopopulation is dominated by pregenerative plants (67.4% of the total number of the individuals studied) with the maximum number recorded for immature individuals (46.5%). The high proportion of pregenerative plants (52.5%) in the T. gesneriana cenopopulation indicates its capability for self-renewal and is characterized by a bimodal age spectrum. According to the classification by T.A. Rabotnov, the cenopopulations of the studied species are normal incomplete. [ABSTRACT FROM AUTHOR]

Polychromous Tulipa suaveolens Roth has a vast range comprising almost the whole Ponto-Caspian Steppe and extending from the south-east of Ukraine to western Kazakhstan. The species is famous for high variation in flower colour, but the pattern of its geographical distribution remains unclear. In the present article, T. suaveolens flower colour variation is studied in 56 natural populations across the European species range. Tepal colours are detected from the digital images using the Lab colour model with two chromatic components—a (the red colour intensity) and b (the yellow colour intensity). The analysis reveals that, throughout the European species range, there is an obvious T. suaveolens flower colour gradient in the direction from the north-east to the south-west, along which the intensity of the red chromatic component increases; the distribution of the yellow chromatic component is interpreted as random. Also, the chromatic component a is found to be linearly dependent on temperature and precipitation parameters. We draw a conclusion that, across the European species range, the identified geographical trends in T. suaveolens flower colour distribution result from natural selection caused by these two abiotic factors.

Background: With cancer as one of the leading causes of death worldwide, accurate primary tumor type prediction is critical in identifying genetic factors that can inhibit or slow tumor progression. There have been efforts to categorize primary tumor types with gene expression data using machine learning, and more recently with deep learning, in the last several years. Methods: In this paper, we developed four 1-dimensional (1D) Convolutional Neural Network (CNN) models to classify RNA-seq count data as one of 17 highly represented primary tumor types or 32 primary tumor types regardless of imbalanced representation. Additionally, we adapted the models to take as input either all Ensembl genes (60,483) or protein coding genes only (19,758). Unlike previous work, we avoided selection bias by not filtering genes based on expression values. RNA-seq count data expressed as FPKM-UQ of 9,025 and 10,940 samples from The Cancer Genome Atlas (TCGA) were downloaded from the Genomic Data Commons (GDC) corresponding to 17 and 32 primary tumor types respectively for training and validating the models. Results: All 4 1D-CNN models had an overall accuracy of 94.7% to 97.6% on the test dataset. Further evaluation indicates that the models with protein coding genes only as features performed with better accuracy compared to the models with all Ensembl genes for both 17 and 32 primary tumor types. For all models, the accuracy by primary tumor type was above 80% for most primary tumor types. Conclusions: We packaged all 4 models as a Python-based deep learning classification tool called TULIP (TU mor C L ass I fication P redictor) for performing quality control on primary tumor samples and characterizing cancer samples of unknown tumor type. Further optimization of the models is needed to improve the accuracy of certain primary tumor types. [ABSTRACT FROM AUTHOR]

Categorizing flowers is quite a challenging task as there is so much diversity in the species, and the images of the different flower species could be pretty similar. Flower categorization involves many issues like low resolution and noisy images, occluded images with the leaves and the stems of the plants and sometimes even with the insects. The traditional handcrafted features were used for extraction of the features and the machine learning algorithms were applied but with the advent of the deep neural networks. The focus of the researchers has inclined towards the use of the non-handcrafted features for the image categorization tasks because of their fast computation and efficiency. In this study, the images are pre-processed to enhance the key features and suppress the undesired information's and the objects are localized in the image through the segmentation to extract the Region of Interest, detect the objects and perform feature extraction and the supervised classification of flowers into five categories: daisy, sunflower, dandelion, tulip and rose. First step involves the pre-processing of the images and the second step involves the feature extraction using the pre-trained models ResNet50, MobileNet, DenseNet169, InceptionV3 and VGG16 and finally the classification is done into five different categories of flowers. Ultimately, the results obtained from these proposed architectures are then analyzed and presented in the form of confusion matrices. In this study, the CNN model has been proposed to evaluate the performance of categorization of flower images, and then data augmentation is applied to the images to address the problem of overfitting. The pre-trained models ResNet50, MobileNet, DenseNet169, InceptionV3 and VGG16 are implemented on the flower dataset to perform categorization tasks. The pre-trained models are empirically implemented and assessed on the various flower datasets. Performance analysis has been done in terms of the training, validation accuracy, validation loss and training loss. The empirical assessment of these pre-trained models demonstrate that these models are quite effective for the categorization tasks. According to the performance analysis, the VGG16 outperforms all the other models and provides a training accuracy of 99.01%. Densenet169 and MobileNet also give comparable validation accuracy. ResNet50 gives the lowest training accuracy of 60.46% as compared with the rest of the pre-trained replica or models. [ABSTRACT FROM AUTHOR]

Abiotic and biotic stresses are the major problems in agriculture alone or in combination. Salicylic acid (SA) is recognized as a plant stress tolerance enhancer chemical by including plant metabolic activities. Besides natural occurring, exogenous usage of SA and its doses depend on plant species and growth conditions. This study was carried out to reveal the positive or negative effects on tulip (Tulipa gesneriana L. cv. Pretty Woman) growth parameters after dipping the bulbs dipped in aqueous solutions (100, 250, 500 and 1000 mg L-1 ) of SA under glasshouse and outdoor condition. The evaluated vegetative and flowering parameters were: emergence rate, first emergence day, duration between first-last emergence, vegetative growth success, flowering capacity, healthy flowering capacity, first flowering day, flower life, flower length and flower stalk length. The data indicated that more than 250 mgL-1 SA doses had a toxic effect on most of the measured vegetative and flowering characteristics (i.e. vegetative growth success, flowering and healthy flowering capacity) under glasshouse condition. While SA had no negative effect on the measured vegetative growth characteristics, high doses of it had also a negative effect on healthy flowering capacity at outdoor conditions. When considering the mentioned observed and measured parameters, before using SA against stress factors exogenously, SA application recommended after determining the toxicity level for any aimed plants and aimed growth conditions at first step [ABSTRACT FROM AUTHOR]

Clover yellow mosaic virus (ClYMV) is reported for the first time in two cultivars of ornamental verbena (Verbena X hybrid) from Christchurch in New Zealand. Sequencing of a ~ 500 bp fragment of the 8 KDa triple gene block and coat protein partial genes indicated the NZ isolates were closely related to ClYMV from verbena in the UK and Poland and more distantly to isolates from clover in Australia and Japan. ClYMV has been intercepted in quarantine in tulips and detected in white clover in Auckland; the verbena isolates may represent a separate incursion into NZ. [ABSTRACT FROM AUTHOR]

Alsop's first business partner of two decades, John Lyall describes their formative years as students at the Architectural Association in London, the influence of various members of Archigram, and sharing a house in Southeast London's not‐so‐salubrious Ladywell district. He recounts a world of music gigs, designing events and parties, and the offices they worked for as young architects before forming their fledgling practice in the 1970s. [ABSTRACT FROM AUTHOR]
