Genes associated with resistance to copper sulfate. (a) Genes correlated with sensitivity to copper sulfate (r > 0.8, p < 0.01) that are differentially expressed among strains in the presence of copper sulfate or between the rich medium and copper sulfate reference pools. (b) Genes differentially expressed and annotated as functioning in copper homeostasis, protein folding or response to oxidative stress.
