Extended Data Fig. 7: Population genomic analyses on diverged genomic regions.
From: Einkorn genomics sheds light on history of the oldest domesticated wheat
(a-b), The percentage of polymorphic sites of each einkorn accession compared to the TA10622 assembly considering SNPs present only in the two highly diverged genomic segments on chromosomes 2A (a) and 5A (b). The circles highlight domesticated einkorn accession that diverged from the TA10622 reference assembly. (c–d), Principal component analyses (PCA) based on SNPs found only in the two large introgressed segments on chromosomes 2A (c) and chromosome 7A (d) revealed that γ accessions cluster with some domesticated einkorn accessions. The circles highlight domesticated einkorn accessions that cluster with wild γ accessions instead of β. e, The percentage of polymorphic sites compared to the TA10622 assembly of the introgressed region on chromosome 7A showed that the majority of the domesticated einkorn accessions (highlighted in the circle) are not diverged from TA10622, which also carries the introgression on chromosome 7A.
