H2O2 generation induces cell death mediated by the overexpression of GhMKK5. (A) The accumulation of H2O2 in transgenic plants visualized by DAB staining. (B) The significant accumulation of H2O2 surrounding the necrotic lesions in #2 plants. The black box indicates the region containing the necrotic lesions. (C) The expression of ROS and cell death-related genes in transgenic plants under normal and R. solanacearum infection conditions. OE, overexpression; Vec, vector control. #2, #4, #5, particular overexpressing lines.
