a–c, The geographical (a) and genetic (b,c) relationships between UC10164 and 64 modern accessions of emmer wheat. The filled areas in a indicate the geographical area enclosed by the domesticated (Dom) accessions in each subgroup. Inset: a zoom of the region from which most of the wild accessions originate. The legend in a applies to all panels. b. The first three principal components are shown for a PCA using all samples (left) and only domesticated samples (right). UC10164 clusters with the modern domesticated emmers, which are all closer to wild Northern Levant emmers than they are to wild Southern Levant emmers. Of the modern domesticated emmers, UC10164 is closest to the Indian Ocean subgroup (green). c, The fractions of unique haplotypes in each accession. Haplotypes were defined using 50-SNP sliding windows. Unique haplotypes have less than 95% genotypic similarity with each of the other accessions. For b and c, the 99,078 SNP sites called in UC10164 were used.
