  1. dN represents protein evolutionary rate measured by non-synonymous substitutions. n is the number of proteins for which PPID, protein evolutionary rate and abundance data are all available. rho is Spearman rank correlation coefficient, and p is the corresponding statistical significance. Bold indicates that p is significant at the statistical significance level of 0.05.
