ONAC066-OE plants increased while ONAC066-RNAi plants decreased oxidative stress tolerance. a Sensitivity of ONAC066-OE, ONAC066-RNAi and WT plants to exogenous H2O2. Leaf fragments were collected from 3-week-old ONAC066-OE, ONAC066-RNAi and WT plants grown under normal condition and were exposed to H2O2 at different concentrations for 48 h. b Chlorophyll contents in leaf fragments after H2O2 treatment in (a). c Sensitivity of ONAC066-OE, ONAC066-RNAi and WT plants to MV. Germinated seeds of ONAC066-OE, ONAC066-RNAi and WT lines were planted on 1/2 MS medium with or without 3 μM MV and allowed for growth for 10 days. d Chlorophyll contents in leaves of ONAC066-OE, ONAC066-RNAi and WT plants after MV treatment in (c). Experiments in (a) and (c) were repeated for three times with similar results. Data presented in (b) and (d) are the means ± SD from three independent experiments and difference between ONAC066-OE/ONAC066-RNAi and WT plants are indicated by asterisks (**p < 0.01) according to Student t test.
