Genome wide comparison among three SDSE genomes. (A) Genome rearrangement map among the three SDSE genomes. Each line joins two orthologues and the color of the lines represents the percentage of similarity between orthologous gene products (blue ≤ 40% ≤ green ≤ 60% ≤ yellow ≤ 70% ≤ orange ≤ 80% ≤ magenta ≤ 90% ≤ red). (B) Cumulative TA-skews for the three SDSE genomes. Gray boxes represent SSRs. Each page region in the GGS_124 and RE378 genomes is indicated with broken lines. The X-axis represents nucleotide position.
