From: Einkorn genomics sheds light on history of the oldest domesticated wheat
a, Einkorn introgressions (highlighted in orange) into ArinaLrFor identified using the k-mer variation approach (IBSpy; Supplementary Note 2). The red square on chromosome arm 1AS corresponds to the region shown in detail in b. b, IBSpy variations between ArinaLrFor (chromosome 1A, position 0–25 Mb) and einkorn. Regions with variation scores of ≤30 (identical by state) are indicated in orange, corresponding to einkorn introgressions. Einkorn_min represents a consensus that shows the lowest variation scores across all resequenced einkorn accessions. The remaining plots illustrate the variation scores between ArinaLrFor and eight selected einkorn accessions. Accession names highlighted in green and grey belong to domesticated groups 1 (dom-g1) and β, respectively. c, The number of introgression segments that could be assigned to a particular einkorn group.
