Population genomics of the wild wheat Aegilops tauschii (Open wild wheat consortium phase II)

Wild wheat relatives of bread wheat represent genetic diversity that can be used for wheat crop improvement. Here, we establish and analyse genomic resources for Tausch’s goatgrass, Aegilops tauschii, the donor of the bread wheat D genome. We determined 493 genetically non-redundant accessions from a diversity panel of over 900 sequenced accessions. We generated high-quality assemblies for 46 accessions, including annotated chromosome-scale assemblies for one accession from each of the three lineages of Ae. tauschii to serve a reference assemblies to anchor the genomic resources. This dataset was generated under the aegis of the Open Wild Wheat Consortium (www.openwildwheat.org). We also resequenced and analysed 60 wheat landraces and generated a chromosome-scale genome assembly for one of these to study the genetic composition and history of the bread wheat D genome. We determined the complexity and origin of the D genome across 17 hexaploid wheat lines by dividing the wheat genomes in..., The full methods are available in the related publication., , # Population genomics of the wild wheat Aegilops tauschii (Open Wild Wheat Consortium Phase II)
