Population genomic analyses in castor bean. a Geographic distribution of 505 castor bean accessions. Blue, red, and green dots on the world map represent the wild Ethiopia (WE), wild Kenya (WK), and domesticated accessions (including landraces and cultivars, LC), respectively. b Geographic distributions of wild castor bean collected from Ethiopia (blue dots) and Kenya (red dots). c Phylogenetic tree of all accessions inferred from whole-genome SNPs, with Jatropha curcas as an outgroup. Three major clades are indicated. The line colors indicate groups of castor bean accessions (WE, WK, landrace, and cultivar). d ADMIXTURE plot for all castor bean accessions. The values of K represent the number of clusters. e PCA plot of the first two eigenvectors of castor bean accessions. f Genetic diversity (θπ) and divergence (FST) among three castor bean populations WE, WK, and LC. g LD decay for three populations (WE, WK, and LC)
