Overview of chromosomal features and variations in soybean genomes. (A) Circos plot of the block structures of the soybean genomes. (B) Chromosomal features and variations of chromosome 1. The numbers of genes, long terminal repeats (LTRs), and terminal inverted repeats (TIRs) are plotted in 100-kb windows. The SNV counts of the soybean cultivars are plotted in 10-kb windows. The shaded boxes represent the dVBs, and the remaining regions represent the sVBs. The black and orange SNV density peaks represent homo- and hetero-SNV densities, respectively. The numbers in the top left of the rectangular lanes are the maximum values of the y-axis. Five Korean soybeans were used to determine the VB type (Baekun, Sinpaldal2, Shingi, Daepoong, and Hwangkeum), and the minimum and maximum possible VB types are therefore one and five, respectively. VBs that were longer than 3 Mb are displayed. W82, Williams 82; BU, Baekun; SPD2, Sinpaldal2; DP, Daepoong; SG, Shingi; HK, Hwangkeum.
