Abstract

Catasetum gladiatorium is endemic to Brazil, being usually found in areas subjected to environmental disturbances that may affect its genetic diversity. Analyses of genetic diversity require extraction of pure DNA through fast and efficient protocols. We propose here an efficient protocol to extract the DNA of C. gladiatorium for use in molecular analyses. DNA was extracted from leaf tissue using eight protocols based on the CTAB method. We tested: (1) two types of plant material maceration (using STE buffer and liquid nitrogen); (2) two CTAB concentrations (2% and 5%); and (3) two concentrations of β-mercaptoethanol (0% and 2%) in the extraction buffer. We performed amplification reactions with the extracted DNA using two ISSR primers. The methods of plant material maceration influenced the quality and amount of DNA extracted from C. gladiatorium. Maceration with liquid nitrogen allowed us to obtain high-quality DNA in all other variations of the tested protocols. On the other hand, maceration with STE yielded DNA at low concentrations and highly degraded. The best results were obtained using 5% CTAB. The absence of β-mercaptoethanol did not influence the quality of the extracted DNA. PCR demonstrated that DNA extraction using the eight tested protocols allowed for amplification with both ISSR markers. The eight protocols were able to extract amplifiable C. gladiatorium DNA, and may thus all be indicated for future molecular studies on the species., Catasetum gladiatorium é endêmica do Brasil e localiza-se em regiões com perturbações ambientais que podem afetar sua diversidade genética. Análises de diversidade genética necessitam de DNA integro, obtido por meio de protocolos de extração rápidos e eficientes. Este estudo objetivou propor um protocolo eficiente para a extração de DNA de C. gladiatorium, para uso em futuras análises moleculares. O DNA foi extraído do tecido foliar com oito protocolos baseados no método CTAB. Testou-se o tipo de trituração do material vegetal (com tampão STE e nitrogênio líquido) e a concentração de CTAB (2% e 5%) e de β-mercaptoetanol (0% e 2%) no tampão de extração. O DNA extraído foi submetido a amplificação com dois primers ISSR. Os métodos de trituração do material vegetal influenciaram na qualidade e quantidade de DNA extraído de C. gladiatorium. A trituração com nitrogênio líquido permitiu a extração de DNA de boa qualidade em todas as demais variações dos protocolos testados, enquanto a trituração com STE possibilitou a extração de DNA com baixa concentração e alta taxa de degradação. Melhores resultados foram obtidos com CTAB à 5%. A ausência de β-mercaptoetanol não influenciou a qualidade do DNA extraído. A amplificação via PCR, demonstrou que o DNA extraído com base nos oito protocolos testados foi passível de amplificação utilizando os dois marcadores ISSR selecionados. Os oito protocolos de extração testados foram capazes de extrair DNA passível de amplificação de C. gladiatorium, e podem ser indicados para futuros estudos moleculares da espécie.

Abstract

To investigate the genetic resistance to northern corn leaf blight (Exserohilum turcicum) disease in the UENF-14 popcorn population and the inclusion of this trait in the analysis, two hundred ten popcorn half-sib families were evaluated using an incomplete block design with treatments arranged in replicates "Sets". Regarding the Families within "Set" (F/S) source of variation, enough genetic variability was found for northern corn leaf blight disease resistance to be explored in the next cycles of the UENF popcorn breeding program. The open-pollinated UENF-14 variety has a source of resistance to this disease in its genetic basis, given that it originated from crossing with an American cultivar with yellow grains that is resistant to disease. These results strengthen the possibility of selecting resistant families across the cycles, so it is concluded that the selection was effective at maintaining the balance in the occurrence of the disease in the study population and that the source of resistance is not lost with advancing cycles. The addition of the foliar disease variable in the analysis is of the utmost importance for the improvement of popcorn as it makes it possible to aggregate genes for resistance to this disease along with agronomic traits of interest. RESUMO. Com o objetivo de investigar a resistência a Exserohilum turcicum na população de milho-pipoca UENF-14, bem como inclusão desta característica na análise, duzentas e dez famílias de meios-irmãos foram avaliados usando delineamento em blocos incompletos, com tratamentos dispostos em repetições dentro "Sets". Em relação à fonte de variação Famílias dentro "Set" (F / S), foi encontrada variabilidade genética suficiente para ser explorada nos próximos ciclos do programa de melhoramento de milho-pipoca da UENF em relação à doença helmintosporiose. A variedade de polinização aberta UENF-14 tem na sua base genética fonte de resistência à doença, devido ao fato que a mesma se originou a partir de cruzamento com a cultivar de grãos amarelos Americana, que é resistente à doença. Tais resultados vêm reforçar a possibilidade de seleção de famílias resistentes através dos ciclos. Portanto, concluiu-se que a seleção foi eficaz em manter o equilíbrio da doença na população em estudo e que a fonte de resistência não é perdida com o avanço dos ciclos de seleção. A adição da variável doença foliar na análise é de extrema importância para o melhoramento do milho-pipoca, pois torna possível agregar os genes para resistência a esta doença juntamente com as características agronômicas de interesse.

Abstract

EST-SSR markers were used to investigate the genetic diversity among and within coffee populations, to explore the possibility of their use for fingerprinting of cultivars and to assist breeding programs. Seventeen markers, developed from ESTs (Expressed Sequence Tags) from the Brazilian Coffee Genome Project, were used. All markers showed polymorphism among the genotypes assessed. The average number of allele per primer was 5.1. The highest polymorphisms were found within C. canephora (88.2%) and rust-resistant varieties (35.3%). About 29.4% of the markers differentiated C. arabica from Híbrido de Timor; it was also possible to identify those closest and farthest from C. arabica . The analysis of population-grouped genotypes revealed a 64.0% genetic diversity among and a 36.0% genetic diversity within populations. The differentiation index was 0.637. Six markers distinguished four rust-resistance varieties, showing their fingerprinting potential. These results demonstrate the usefulness of EST-SSR markers for cross orientation, in diversity and introgression studies, and in genetic mapping. No estudo da diversidade genética entre e dentro de populações de café, foram usados marcadores EST-SSR, visando avaliar seu potencial para identificar cultivares comerciais e assistir programas de melhoramento. Os 17 marcadores utilizados foram desenvolvidos a partir das seqüências ESTs do Projeto Brasileiro do Genoma Café. Em todos os marcadores observou-se polimorfismo entre os genótipos avaliados, com um número médio de 5,1 alelos por primer. Os maiores polimorfismos foram constatados dentro de C. canephora (88,2%) e em variedades resistentes à ferrugem (35,3%). Dos marcadores analisados, 29,4% distinguiram C. arabica dos Híbridos de Timor (HDT), sendo possível identificar os mais próximos e os mais distantes de C. arabica . A análise dos genótipos agrupados por população revelou diversidade genética de 64% entre populações e 36% dentro delas, com um índice de diferenciação de 0,637. Em seis marcadores distinguiram-se quatro variedades resistentes à ferrugem, constando seu potencial para fingerprint. Esses resultados demonstram a utilidade dos EST-SSR para orientações dos cruzamentos e estudos de diversidade, introgressão e mapeamento genético.

Abstract

Compared with the common corn, popcorn shows greater susceptibility to pests and diseases occurrence, being the use of resistant cultivars the most efficient strategy. In this regard, Germplasm Banks deserve special attention because they contain accessions that can be used as sources of resistance in breeding programs. The State University of Northern Rio de Janeiro (UENF) maintains a popcorn Germplasm Bank with accessions from tropical and temperate countries, including Diversity Centers for the species. In this study, we investigated the performance of 37 popcorn accessions landraces, hybrids, and inbreed lines - from the Germplasm Collection of UENF's Popcorn Breeding Program with respect to the fungal leaf diseases northern leaf blight (NLB) and southern leaf blight (SLB), caused by Exserohilum turcicum and Bipolaris maydis, aiming to select promising accessions for genetic resistance to be used in future crosses to generate new resistant cultivars for farmers. The dendrogram scattering by the UPGMA multivariate technique was efficient in discriminating resistant accessions. Satisfactory results were obtained for resistance to NLB in accessions L71, L75, L76, P7, and PARA-172, which can thus be considered remarkable sources of resistance. For resistance to SLB, the superior accessions that can be indicated as sources of resistance are ARZM-05083, ARZM-07049, and PARA-172. [ABSTRACT FROM AUTHOR]

Abstract

The use of topcross has proven to be an interesting option for the maize crop; however, for the popcorn, there is little information about the choice of the appropriate tester. In this context, this study aimed to analyze four testers including two open pollinated varieties(BRS Angela and UENF-14), one topcross hybrid (IAC125) and a line (P2), to evaluate the combining ability of 50 S3 families of popcorn, obtained from the UENF-14 variety. Popcorn families were evaluated for grain yield (GY) and popping expansion (PE). The estimates of general and specific combining abilities were obtained and the discrimination of each tester through differentiation index was carried out. The testers BRS Angela (for GY) and IAC 125 (for PE) were the most adequate, when combined with the best S3 families derived from UENF-14, for the production of popcorn hybrids for the Northern and Northwestern Fluminense Regions.
