Abstract: Aegilops tauschii, the diploid wild progenitor of the D-subgenome of bread wheat, constitutes a reservoir of genetic diversity for improving bread wheat performance and environmental resilience. To better define and understand this diversity, we sequenced 242 Ae. tauschii accessions and compared them to the wheat D-subgenome. We characterized a rare, geographically-restricted lineage of Ae. tauschii and discovered that it contributed to the wheat D-subgenome, thereby elucidating the origin of bread wheat from … Show more

“…This could represent an ancestral haplotype found in both lineages which underwent incomplete lineage sorting, or a case of recent interlineage haplotype exchange. Cases of haplotypes shared across Lineages 1 and 2 were also observed for pest (Cmc4) and disease resistance (Sr46) genes 23 . Lineage 2, the recognized ancestral diploid donor of the D-subgenome of hexaploid wheat 3 , had greater Glu-D1 molecular haplotype diversity than Lineage 1.…”

“…Interestingly, the wheat 5+10 allele clustered within the unique Lineage 3 sub-clade. Supporting the inheritance of the 5+10 allele from Lineage 3, Gaurav et al (2021) 23 observed genome-wide contribution of Lineage 3 to wheat ancestry. These findings reveal that the Lineage 3 contribution to the wheat D-subgenome included the very valuable Glu-D1 5+10 allele, arguably one of the most important genes defining the quality of bread wheat.…”
