Figure 2

Dependence of evolutionary rate in ascomycetes on the number of protein interactions and expression level. The averaged relative rate R decreases with increasing number of interaction partners (τ ≈ -0.06) and the expression level (τ ≈ -0.23). The 95% bootstrap intervals for Kendall's τ values obtained from the six species comparisons are always negative (see table 1). The linear regression curves (red) appear concave on the log-transformed x-axis.
