Fig 2. Genomic variation patterns in three Capsella species.
Variation was visualized with principal component analyses based on the SNPs of C. grandiflora (CG), C. orientalis (CO), and four populations of C. bursa-pastoris (Cbp) (Asia (ASI), Central Asia (CASI), Europ (EUR), and Middle East (ME)). The left plot shows variation in the three species with lines connecting subgenomes of corresponding Cbp accessions and the dash-dotted circles highlighting two subgenomes of Cbp. The middle and right plots show only the variation within the subgenomes of C. bursa-pastoris (CbpCg and CbpCo).
