FIG 4.

Comparison of stress tolerance to oxidative agents between the WT and ΔAopex14/17 mutant strains. (A) Colony morphologies of the WT and mutant strains incubated on TG medium supplemented with 0.02 to 0.04 mM menadione and 2.5 to 10 mM H₂O₂ for 6 days. (B) Relative growth inhibition (RGI) values of the WT and mutant strains incubated on TG medium supplemented with 0.02 to 0.04 mM menadione and 2.5 to 10 mM H₂O₂ for 6 days. The asterisk indicates a significant difference between the mutant and the WT strains (*, P < 0.05; **, P < 0.01; ***, P < 0.001).
