  1. Analysis A was based on 82 organisms; analysis B was based on a subset of 24 organisms, which are phylogentically remote from each other. Pearson correlation coefficients were computed. aControlling for codon usage bias; bcontrolling for habitat type; ccontrolling for growth rate. NA, when the Pearson correlation coefficient was not statistically significant, partial correlation was not computed.
