Segmental duplications in the rice genome. Segmentally duplicated rice genes are displayed by connecting lines among the 12 rice chromosomes (Os01 – Os12). Duplicated genes were organized in 24 pairs of genome segments located throughout the whole genome as indicated by differing colors of bars in the outer lane. Centromere positions are indicated by white dots. Mean Ks values of duplicated genes are shown in yellow bar plots along the 12 rice chromosomes (2 Mb bins, scale: 0 – 2, scale spacing 0.5). Histograms in pink show the ratio of duplicated genes to the total number of annotated genes (2 Mb bins, scale: 0 – 0.8, scale spacing: 0.2). Positions are in Mb.
