Overexpression of VaPYL4 improves resistance of transgenic Arabidopsis plants to salt and drought stress. A Phenotypes of WT and OE plants under salt (NaCl) and mannitol conditions. Plants growing on normal 1/2 MS medium were shown as the control (ctrl). Scale bars: 1 cm. B Length of primary roots of Arabidopsis plants shown in (A). At least 25 seedlings were used for the measurement for each genotype. C Phenotypes of WT and OE plants under drought conditions. Drought treatment was performed by withholding water for 12 or 15 days, then the plants were re-watered for 5 days. Survival rates were measured after the recovery. Data are means ± SD. **P < 0.01; ***P < 0.001. Similar results were observed in three independent experiments
