Deletion of OYE2 causes sensitivity to acrolein. Sensitivity was determined by spotting strains on YEPD plates containing various concentrations of acrolein, H2O2, or crotonaldehyde. Cultures of wild-type (wt), oye2, oye3, and oye2 oye3 cells were grown to stationary phase and the A600 was adjusted to 1, 0.5, 0.1, 0.05, or 0.01 before the cells were spotted onto plates. Growth was monitored after 3 days of incubation at 30°C. Results are shown for plates containing no oxidant (YEPD), 3 mM acrolein, 4 mM H2O2, and 2 mM crotonaldehyde.
