Population structure of 2,179 accessions based on 3,834 polymorphic SNPs: (A) plot of LnP(D) and an ad hoc statistic ΔK calculated for K ranging from 1 to 10, with each K repeated thrice; (B) population structure at K = 5, with each accession represented by a single vertical line that is partitioned into K colored segments, with lengths proportional to the estimated probability membership value (y-axis); (C) frequency distribution of accessions belonging to each predicted group by country of origin, with all countries that had <40 accessions combined in to “others”; (D) frequency distribution of accessions belong to each predicted group by ecology, with “others' referring to accessions from floating, mangrove, deep and shallow forest swamp, and hydromorphic ecologies.
