Characterization of transcription factors (TFs) involved in the oxidative stress response. (A) Oxidative stress sensitivity of eight TF mutants. The mycelial growth of the TF deletion mutants was evaluated on complete medium (CM) and on CM supplemented with 10 mm H₂O₂, 0.1 mm menadione or 1 mm diamide. Photographs were taken 5 days after inoculation. (B) Transcript abundances of peroxidase genes in the TF mutants. The transcript levels of FCA6, FCA7, FPX1 and FPX15 were analysed by quantitative real‐time polymerase chain reaction (qRT‐PCR). Total RNA was isolated from wild‐type (WT) and TF deletion mutant strains grown for 30 min in CM only or in CM supplemented with 5 mm H₂O₂.
