Fig. 4From: Population Dynamics Among six Major Groups of the Oryza rufipogon Species Complex, Wild Relative of Cultivated Asian RiceChloroplast haplotype network. Haplotype network for the ORSC and O. sativa samples based on 25 chloroplast variants; single mutations indicated as hatches between haplotypes; chloroplast groups (cpGroup) I to VIII indicated in rectangles; size of nodes (circles) is proportional to haplotype frequency; colors indicate proportion of individuals from each subpopulation (based on GBS data at K = 6 in Fig. 1a) that carry the haplotype; gray indicates admixed accessions; for more detail, see Additional file 12: Figure S8 and Additional file 1: Table S1Back to article page
