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 کاملDissecting miRNAs in Wheat D Genome Progenitor, Aegilops tauschii
As the post-transcriptional regulators of gene expression, microRNAs or miRNAs comprise an integral part of understanding how genomes function. Although miRNAs have been a major focus of recent efforts, miRNA research is still in its infancy in most plant species. Aegilops tauschii, the D genome progenitor of bread wheat, is a wild diploid grass exhibiting remarkable population diversity. Due t...
متن کاملSNPing Aegilops tauschii genetic diversity and the birthplace of bread wheat.
Towards the end of World War II, McFadden & Sears (1946) published a lengthy and classic paper on the origin of hexaploid or bread wheat. In the appendix to this paper they acknowledged that Kihara (1944) had also independently identified Aegilops tauschii (syn. Ae. squarrosa, Tritcum tauschii) as the D-genome donor of bread wheat. Since then, there have been many studies on the taxonomy, biolo...
