From: Genomic patterns of nucleotide diversity in divergent populations of U.S. weedy rice
Population structure assessed by InStruct. Each individual accession is represented by a colored bar, partitioned to reflect an individual's relative proportion of genetic membership in a given cluster K. A) Results of analysis for U.S. weedy rice accessions (n = 58), showing progression of clustering as K increased to optimal K = 6. The order of accessions is the same as in Additional file 1 and in all plots. B) Population structure results for the entire Oryza panel (n = 209), showing clustering at optimal K = 9. Inset plot shows clustering of U.S. weedy rice. Samples are in the same order as Additional file 2, and O. rufipogon samples are sorted by country of origin. Weedy rice accession names color coded by cytotype: DDD light green, NDD orange, NND blue, DDN red, NNN dark green, Black - no data
