<p>(A) Phenotypes of transgenic plants and WT under drought stress. Four-week-old plants were treated under drought stress conditions for 3 days. The pictures were taken after re-watering for 5 days. The experiments were representative of four independent experiments. (B) The drought tolerance was evaluated by the survival rate. The survival rates were calculated from 18 plants for each genotype. (C) The chlorophyll index from ten plants was measured using a chlorophyll meter (SPAD502). (B), (C) WT and transgenic plants were re-watered for two weeks. The results shown are the mean ± SD, n = 4 replicates for each group (***P<0.001, **P<0.01, and *P<0.05 compared to WT).</p
