NapA, SrrA and AtfA play differential roles in Aspergillus nidulans antioxidant response. (A) Conidia (1 × 10³) from strains CLK43 (WT), COSsrrA3 (ΔsrrA), CFL7 (ΔnapA), TFLΔatfA-04 (ΔatfA), CAM7 (ΔatfA ΔnapA), CAM6 (ΔsrrA ΔnapA), CAM8 (ΔsrrA ΔatfA), and CAM9 (ΔsrrA ΔatfA ΔnapA) were inoculated by dropping spore suspensions on the center of supplemented MM plates containing H₂O₂ or menadione (Md) at the indicated concentrations, and incubated at 37°C for 4 days. (B) Mycelial plugs cut from the growing edge of 5-day old colonies from strains CLK43, COSsrrA3, CFL7, TFLΔatfA-02, CAM7, CAM6, CAM8, and CAM9 were transferred to plates containing H₂O₂ or menadione at the indicated concentrations, and incubated at 37°C for 4 days.
