Geographic locations and population structure of A. thaliana. a Map of the locations sampled (black points) and sequenced (red points) in this study. b Population structure of A. thaliana based on admixture analysis of strains from (a). “Others” indicates strains from USA, Japan, and New Zealand, which most probably reflects recent introduction given that A. thaliana originated in Europe. c Phylogenetic tree of A. thaliana strains from (a). Black lines indicate strains from USA, Japan, and New Zealand. d Principle component analysis (PCA) of A. thaliana. Shaded areas indicate the populations from different regions: pink refers to the European population (popE), blue refers to popN, and yellow refers to popY. e The locations of different populations color-coded as in (d)
