Figure 2.

Hierarchical clustering of differentially expressed genes. Genes with significant expression differences among strains in both media (strain), in copper-sulfate medium (strain*CuSO4), in rich medium (strain*YPD), and between copper sulfate and rich medium reference pools (YPD vs CuSO4) for p < 0.05 (yellow) and p < 0.01 (blue). Groups of functionally related genes are also shown.
