Geographic distribution and population structure. a Geographic distribution of the 484 Boechera stricta accessions. Each individual was assigned into one of the four genetic groups, WES (blue), COL (red), UTA (light blue), and NOR (gold), as well as Admixed (gray). b Population structure of B. stricta inferred by Admixture. Each vertical bar represents an individual, with different colors representing one of the genetic ancestries. The number of individuals in each lineage is also shown. K represents the number of structure groups for each analysis. c Genetic principal component analysis (PCA) of B. stricta based on genome-wide SNPs. Percent variation explained by each component is shown in parentheses. d Neighbor-joining (NJ) tree based on SNP data. Color scheme for genetic groups is the same in ad
