Variant distribution profiles over the 12 chromosomes of MucoRice-CTB and WT rice lines. (A) Variant distribution calculated in consecutive non-overlapping 500-kbp windows was averaged for three MucoRice-CTB lines or two WT lines. Blue lines in the upper half of each graph represent average distributions for MucoRice-CTB lines, orange lines in the bottom half represent average distributions for WT lines. The vertical axis represents the number of variants; the values increase upward for MucoRice-CTB lines and downward for WT lines. Black vertical lines in each graph indicate centromere positions. (B) The maximum differences in the numbers of variants per 500-kbp window between MucoRice-CTB and WT lines on each chromosome.
