Stress tolerance assays of the WT, ∆FocGCS, and complemented strains. a Colony morphology of the indicated strains on PDA plates supplemented with 0.5 mM H2O2, 1 M NaCl, or 1 M sorbitol. Photos were taken after incubation at 28 °C for 5 days. b Colony growth inhibition incubated with 0.5 mM H2O2. c Colony growth inhibition incubated with 1 M NaCl or 1 M sorbitol. The inhibition rate was calculated by comparing the colony diameter under stress conditions with that under normal conditions. d Colony morphology of the indicated strains on PDA plates with different pH values. Photos were taken after incubation at 28 °C for 5 days. e Colony growth inhibition under different pH conditions. The inhibition rate was calculated by comparing the colony diameter under different pH conditions with that under condition of pH = 6.0. The mean values ± SD were calculated from three independent experiments, and asterisks indicate significant differences from the WT group (Student’s t-test, **P < 0.01)
