Testing the neutral hypothesis of yeast gene expression evolution

Variables correlated Spearman’s ρ P value
ED, TI −0.147 3.7 × 10−18
MS, TI −0.142 3.9 × 10−17
ED/MS, TI −0.087 3.2 × 10−7
SDm/MS, TI −0.030 0.13

ED, evolutionary distance in gene expression level between S. cerevisiae strains; MS, mutational size measured by gene deletion; SDm, standard deviation in relative gene expression level among mutation accumulation lines; TI, gene expression trait importance.
