FIGURE 3.

Genomic variation of Helianthus maximiliani partitioned by (a) principal component analysis (PCA) and (b) discriminant analysis of principal components. Both analyses were conducted on the full SNP dataset for all ex situ, wild contemporary, commercial, and selected populations. In panel (a), wild contemporary individuals are behind the dense cluster of ex situ and commercial individuals just to the right of the origin. Missing data (2.5% of all observations) in the PCA were replaced with the mean allele frequency value. Different seed source types are depicted as different colors (turquoise: ex situ; red: wild contemporary; yellow: commercial; and orange: selected)
