Genes dependent on Msn2/Msn4p. Wild-type, msn2 msn4, and yap1 strains were exposed to H₂O₂ and heat shock, and genes whose expression was affected in the msn2 msn4 mutant strain are shown. The display represents data averaged from duplicate experiments. The effects on these genes of overexpression of MSN2, MSN4 (this study), and YAP1 (DeRisi et al., 1997) are also shown. Genes fell into three classes based on their expression patterns, marked by bars to the right of the cluster diagram: (A) genes partially dependent on Msn2/Msn4p in response to both stresses; (B) genes largely dependent on Msn2/Msn4p in response to both stresses; and (C) genes dependent on Msn2/4p only in response to heat shock.
