Homologous dotplot between Medicago (Medicago truncatula) and Soybean (Glycine max) genomes

    The best, secondarily best, and other matched homologous gene pairs output by BLAST were dotploted by red, blue, and gray colors in this figure, respectively. Colinear gene blocks were inferred and circled out. We used median synonymous substitution rates or Ks to help distinguish the blocks from different events. Based chromosomal breakpoints and positional closeness, a set of soybean chromosomal regions making up one copy of a medicago chromosome are circled in red, and the other set making up to another copy of the same medicago chromosome are circled in black.
