Table 1 Evolutionary analysis of S. cerevisiae Correlations between evolutionary rate, number of connections and expression level of proteins and the confidence intervals for Kendall's τ statistic obtained for the different ascomycete species. Values of τ that have associated p-values < 0.01 are highlighted in bold. X 1 denotes correlation with evolutionary rate obtained from a pairwise sequence comparison between S. cerevisiae and species X; X 2 differs from X 1 only in that the evolutionary rate was obtained using a maximum likelihood estimate. M denotes a rate obtained with respect to S. mikatae, B to S. bayanus, C to S. castellii, K to S. kluyveri, A to C. albicans, and P to S. pombe.
