Abstract: Aegilops tauschii, the diploid wild progenitor of the D subgenome of bread wheat, is a reservoir of genetic diversity for improving bread wheat performance and environmental resilience. Here we sequenced 242 Ae. tauschii accessions and compared them to the wheat D subgenome to characterize genomic diversity. We found that a rare lineage of Ae. tauschii geographically restricted to present-day Georgia contributed to the wheat D subgenome in the independent hybridizations that gave rise to modern bread wheat.

“…6, 7). The L2 origin of Rwt4 is consistent with L2 being the major contributor of the wheat D-genome, however, the L1 origin of Rwt3 is more remarkable considering that the L1 signature in wheat is mostly concentrated around a 5 Mb region surrounding the Rwt3 candidate 14 (Supplementary Fig. 8).…”

“…In the current study, we aimed to elucidate the genetic basis of APR and ASR against stripe rust in WEW from Israel by using a GWAS, which was shown to be a powerful approach for mapping resistance genes in wheat and its wild relatives [40]. The advantage of using WEW for GWAS is the fast rate of linkage disequilibrium (LD) decay in the populations of wheat wild relatives, which increases the resolution of trait mapping [28].…”
