Effects of slmapk3 mutants on ROS production under heat stress. a DAB staining, b NBT staining, c H2O2 content, d O2•− content, and (e) SlRBOH1 relative expression. For (a) and (b), the top panel represents leaves grown at 25 °C, and the bottom panel represents leaves treated with 42 °C for 24 h. Data are represented as mean ± SD of three biological replicates. Statistical differences at each time point of treatment are labeled with different letters according to Duncan’s multiple range test at P < 0.05
