The relationship between number of protein-protein interactions and evolutionary rate between S. cerevisiae and S. pombe. (a) The relationship between number of protein-protein interactions and evolutionary rate for all 2119 orthologs with protein interaction data. Several outliers are not shown but were included in the analysis. (b) Average evolutionary rates of genes binned by their number of protein-protein interactions.
