Figure 5From: Comparative analysis of the Saccharomyces cerevisiae and Caenorhabditis elegans protein interaction networksDependence of evolutionary rate in nematodes on the number of protein interactions and CAI. The estimated evolutionary rate decreases with increasing number of interaction partners (τ ≈ -0.03) and the expression level (τ ≈ -0.30). We have again transformed the x-axis in the scatterplot of rate vs. connectivity which leads to the concave shape of the regression line (red).Back to article page
