a, Each segment represents a stacked histogram of tiled windows of 100 loci. Species: 1, O. sativa vg. japonica; 2, O. sativa vg. aus (N 22); 3, O. sativa vg. indica (IR 8); 4, O. sativa vg. indica (93-11); 5, O. rufipogon; 6, O. nivara; 7, O. glaberrima; 8, O. barthii; 9, O. glumaepatula; 10, O. meridionalis; 11, O. punctata; 12, O. brachyantha; 13, L. perrieri. Recombination rate is shown in the outer ring, ranging from 0 to 9 cM/Mb, based on the integrated genetic/physical map of rice (constructed from data from Harushima et al.103 and McCouch et al.104) for O. sativa vg. japonica downloaded from http://archive.gramene.org/. Triangles show the position of rice centromeres (see URLs). b, Differential correlations in O. sativa vg. japonica of gene age group prevalence (calculated over 191 2-Mb non-overlapping windows) with chromosome recombination rate. Plots show individual points color-coded by chromosome fitted by simple linear regression. Pearson’s correlation coefficient (r) and P value are shown for each plot.
