Distinct responses of ΔkdmA and ΔkdmB mutants to various kinds of oxidative stress. (A) Heatmap of altered expression levels of genes encoding oxidative stress-related proteins in ΔkdmA and ΔkdmB mutants. (B) Colony appearance and radial growth inhibition after inoculation of 1 × 105 conidia on solid YG medium containing oxidative stressors. (C) Catalase activity of the WT and mutant strains. (D) SOD activity of the WT and mutant strains shown in non-denaturing polyacrylamide gels. Relative intensities of each enzyme’s activity are shown below. Statistical significance of differences between WT and mutant strains was evaluated using Student’s t-test: ** p < 0.01.
