Figure 3. The sensitivity of wild type, KO3, and KO8 mutant lines to heat stress. (A) The time scale of the heat stress. (B) Phenotype of the seedlings before and after 7 d from the stress. (C) Immuno-blotting analysis of oxidized proteins during heat stress conditions. (D) Lipid hydroperoxide content and survival rate after 7 d from the stress in the wild type and mutant cells.
