FIG 4.

The DTT/thermal stress sensitivity in the ΔclxA mutant can be rescued by extracellular Ca²⁺ in a calcineurin-dependent way. (A and C) Quantitative total conidial production for the indicated strains grown on solid MM in the presence or absence of 200 mM CaCl₂ at 30 or 42°C for 2.5 days. (B and D) Quantitative total conidial production for the indicated strains grown on solid MM in the presence or absence of 200 mM CaCl₂ and/or 2 mM DTT at 30°C for 2.5 days. Different lowercase letters on the bars of each group represent significant differences among strains (Tukey's multiple-comparison test, P < 0.05).
