Abstract The D-genome progenitor of wheat (Triticum aestivum), Aegilops tauschii, possesses numerous genes for resistance to abiotic stresses, including drought. Therefore, information on the genetic architecture of A. tauschii can aid the development of drought-resistant wheat varieties. Here, we evaluated 13 traits in 373 A. tauschii accessions grown under normal and polyethylene glycol-simulated drought stress conditions and performed a genome-wide association study using 7,185 single nucleotide polymorphism (SNP) markers. We identified 208 and 28 SNPs associated with all traits using the general linear model and mixed linear model, respectively, while both models detected 25 significant SNPs with genome-wide distribution.

O presente documento refere-se à avaliação prática do potencial da GWAS no melhoramento dos cafeeiros das espécies Coffea arabica e Coffea canephora. O objetivo geral é orientar a aplicação eficiente da GWAS em características produtivas, agronômicas e de resistência a doenças e pragas do cafeeiro. Para isso, um novo método para o estudo de associações genômicas foi desenvolvido e avaliado via simulação, em termos de poder de detecção de genes. O objetivo específico é possibilitar a identificação de marcadores genéticos úteis ao melhoramento do cafeeiro. |

Root anatomical traits, which include cortical area, aerenchyma area, and xylem features, influence the absorption and translocation of water and nutrients, oxygen transport and the mechanical strength of the root system. While a number of studies have shown promising functional benefits of anatomical root traits in conferring resource acquisition efficiency, very little is known about the genetic mechanisms underlying natural phenotypic variation of these traits. In this study, we evaluated 336 Oryza sativa accessions selected from the rice diversity panel for 4 root anatomical traits including, root cross-section area, aerenchyma, and xylem features in well-controlled greenhouse environment. Considerable phenotypic variation was observed in all root... |
