Genome-wide distribution of interspecific introgression and genomic features. The rings of the circle, from outside to inside, show chromosomes including (i) chromosome arms (gray color) and pericentromeric regions (green color), (ii) chromosomal distribution of introgression rates in the whole population, (iii) chromosomal distribution of domestication-related QTL as indicated by red bars in corresponding ring, (iv) chromosomal distribution of selective sweeps as indicated by red bars in corresponding ring, (v) chromosomal distribution of interspecific introgression in each of the 12 G. max and 10 G. soja accessions, as indicated by the 22 rings, whose genomes each possesses more than 5% introgressed fragments. In these 22 rings, the G. max segments were shown in blue and the G. soja segments were shown in orange
