Phenotypes and sensitivity of thiol peroxidase mutant strains to redox stresses. (A) Sensitivity of S. cerevisiae WT and different thiol peroxidase mutant cells to indicated concentrations of hydrogen peroxide, diamide, DTT, and menadione. Cells in series of 10× dilutions for each strain were grown on plates with indicated stress inducers for 48 h. (B) Viability of WT cells and 8Δ cells during 2-h treatment with indicated stressors. (C) Replicative life span of WT and thiol peroxidase mutant strains.
