“…Finding natural products that work in disease control has a number of economic and environmental benefits. The global threat to crop productivity represented by gap between agricultural production and food demand is steadily increasing year by year [ 6 , 7 ]. Three strategies have been used to control SBR: applying chemical fungicides, employing specific cultivation practices, and most recently breeding or engineering of SBR-resistant soybean cultivars [ 8 – 10 ].…”

The number of measurements needed to obtain high reliability for traits related to enzymatic activities and photosynthetic compounds in soybean plants infected with Phakopsora pachyrhizi

Asian rust affects the physiology of soybean plants and causes losses in yield. Repeatability coefficients may help breeders to know how many measurements are needed to obtain a suitable reliability for a target trait. Therefore, the objectives of this study were to determine the repeatability coefficients of 14 traits in soybean plants inoculated with Phakopsora pachyrhizi and to establish the minimum number of measurements needed to predict the breeding value with high accuracy. Experiments were performed in a 3x2 factorial arrangement with three treatments and two inoculations in a random block design. Repeatability coefficients, coefficients of determination and number of measurements needed to obtain a certain reliability were estimated using ANOVA, principal component analysis based on the covariance matrix and the correlation matrix, structural analysis and mixed model. It was observed that the principal component analysis based on the covariance matrix out-performed other methods for almost all traits. Significant differences were observed for all traits except internal CO2 concentration for the treatment effects. For the measurement effects, all traits were significantly different. In addition, significant differences were found for all Treatment x Measurement interaction traits except coumestrol, chitinase and chlorophyll content. Six measurements were suitable to obtain a coefficient of determination higher than 0.7 for all traits based on principal component analysis. The information obtained from this research will help breeders and physiologists determine exactly how many measurements are needed to evaluate each trait in soybean plants infected by P. pachyrhizi with a desirable reliability.

O Brasil é um dos lideres mundiais em produção de animais de interesse zootécnico. Porém, para manter este status, precisa investir grandemente em pesquisas que visem aumentar a produtividade animal. No âmbito do melhoramento genético animal, o Brasil conta com muitos grupos que desenvolvem estudos de grande interesse nesta área. São estudos que vão desde os clássicos trabalhos de estimativas de componentes de variância e parâmetros genéticos, passando por trabalhos de modelagem estatística até chegar aos trabalhos mais recentes envolvendo genética molecular aplicada ao melhoramento animal. Assim, a presente revisão tem por objetivo sumarizar os caminhos pelo qual o melhoramento genético animal no Brasil trilhou ao longo da primeira década do século 21, os quais podem indicar os avanços obtidos e os novos desafios.

“…Among the several types of molecular markers, SNP have stood out for being the most abundant type of polymorphism in genomes, for being codominant and biallelic, and for automatizing the technique used to obtain these markers (Resende et al 2008;Liao and Lee 2010). In recent years, these markers have frequently been used in studies on humans (Gabriel et al 2002;Ojopi et al 2004;Pinto et al 2008;Gnirke et al 2009) and in some animal and plant species (Abatepaulo et al 2008;Caetano 2009;Yang et al 2013); (Zhang et al 2011;Neves et al 2013Neves et al , 2014Zhang et al 2015;Resende et al 2016).

High-throughput targeted genotyping using next-generation sequencing applied in Coffea canephora breeding

The use of molecular markers to detect polymorphism at DNA level is one of the most significant developments in molecular biology techniques. With the development of new next-generation sequencing technologies, the discovery of SNP became easier and faster, and the costs of data point were reduced. The development and use of SNP markers for coffee have provided new perspectives for the evaluation of genetic diversity and population structure via different statistical approaches. In this study, 72 Coffea canephora genotypes were analyzed to identify the SNP markers and apply them to genetic studies and selection of parents/hybrids in genetic breeding. As many as 117,450 SNP were identified using the RAPiD Genomics platform. After quality analyses, 33,485 SNP were validated for analyses of genetic diversity and population structure. Genotypes were separated based on their varietal groups, and Hybrids were differentiated using the clustering and Bayesian approach. Coffee accessions mistakenly identified in the germplasm and breeding program were detected. The Conilon varietal group presented the lowest genetic dissimilarity values, suggesting the introduction of new accessions in the germplasm bank. The highest genetic distances values were observed among genotypes of the heterotic groups (Conilon and Robusta). The markers were efficient in evaluating the genetic diversity and population structure of C. canephora. Promising crosses were selected within and between the varietal groups. Hybrids with greater genetic distances were selected, which were important for C. canephora breeding programs.
