Tolerance to hyperosmotic stress and mycelial morphology: WT versus ΔAoime2 mutants. (A) Comparison of colonial morphology under high-osmolarity stress between WT and ΔAoime2 mutants. (B) RGI values of WT and ΔAoime2 mutants grown on TG plates supplemented with 0.2 M NaCl or 0.5 M sorbitol. Error bars: SD from three replicates, asterisk: significant difference between mutant and WT strain (Tukey’s HSD, p < 0.05). (C) Mycelia of WT and ΔAoime2 mutant strains were examined using scanning electron microscopy (SEM). Pink arrows: deformed mycelia in ΔAoime2 mutants. Bar = 10 μm. (D) Traps produced by WT and ΔAoime2 mutant strains were examined using transmission electron microscopy. Pink arrows: ED bodies in trap cells of WT and ΔAoime2 mutant strains; blue arrows: separation of cell wall and plasma membrane in ΔAoime2 mutants.
