Genome-Wide Association Study of Grain Architecture in Wild Wheat Aegilops tauschii
Aegilops tauschii, the D-genome progenitor of Triticum aestivum, encompasses huge diversity for various traits of potential economic importance such as yield, biotic and abiotic stress tolerance, quality and nutrition. In the present study, variation for grain size in Ae. tauschii germplasm was studied and its genetic basis dissected using genome-wide association study (GWAS). Grain length, wid...
متن کاملGenome-wide association study of 29 morphological traits in Aegilops tauschii
Aegilops tauschii is the D-genome progenitor of hexaploid wheat (Triticum aestivum). It is considered to be an important source of genetic variation for wheat breeding, and its genome is an invaluable reference for wheat genomics. We conducted a genome-wide association study using 7,185 single nucleotide polymorphism (SNP) markers across 322 diverse accessions of Ae. tauschii that were systemat...
متن کاملGenome-wide association study of drought-related resistance traits in Aegilops tauschii
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 drou...
متن کاملGenome-wide analysis of the heat shock transcription factor family in Triticum urartu and Aegilops tauschii
Heat shock proteins (Hsps) are believed to play essential roles in developmental processes and in responses to heat stress. Heat shock transcription factors (Hsfs) are important Hsp regulators, but their functions are poorly understood, especially in wheat. In this study, a comprehensive bioinformatics analysis was conducted in wheat A and D genome donors, Triticum urartu and Aegilops tauschii,...
متن کاملMolecular mapping of segregation distortion loci in Aegilops tauschii.
Distorted segregation ratios of genetic markers are often observed in progeny of inter- and intraspecific hybrids and may result from competition among gametes or from abortion of the gamete or zygote. In this study, 194 markers mapped in an Aegilops tauschii F2 population were surveyed for distorted segregation ratios. Region(s) with skewed segregation ratios were detected on chromosomes 1D, 3...
