Drought-induced accumulation of proline, soluble and ROS in ONAC066-OE and ONAC066-RNAi plants. a Proline content and (b) soluble sugar content. c In situ detection of H2O2 and superoxide anion in leaves by DAB and NBT staining, respectively. d H2O2 levels in leaves. Leaf samples were collected from 3-week-old ONAC066-OE, ONAC066-RNAi and WT plants grown under normally watered and drought-stressed (at 5 days after water withholding) conditions and were subjected to physiological measurements. Experiments in (c) were repeated for three times with similar results. Data presented in (a), (b) and (d) are the means ± SD from three independent experiments and significant difference between ONAC066-OE/ONAC066-RNAi and WT plants under the same treatment are indicated by asterisks (**p < 0.01 and *p < 0.05) according to Student t test.
