N, number of genes; dSM, promoter divergence (see text); Kp, promoter substitution rate; Ka, non-synonymous substitution rate; Ks, synonymous substitution rate. Mean (top), median (middle), and standard deviation (bottom) are indicated for each variable. Numbers in bold indicate significant differences at p < 0.001 in each expression group with respect to the rest (two-sample Wilcoxon-Mann-Whitney test). The last row shows the p value of Kruskal-Wallis (K-W) test that evaluates differences between the three tissue expression breadth groups. |
