UV-C–Induced Necrosis.
Plants were irradiated at 20, 25, and 30 d postgermination (dpg). Necrotic lesions were scored 24 h after irradiation and trypan blue staining. Bars show the average number of necrotic lesions ± sd per leaf. Data were obtained from three biological repeats, each one consisting of 20 to 30 leaves. Asterisks indicate a significant difference (P < 0.05) between irradiated (UV) and control (ct) plants. wt, wild type.
