AtEDT1/HDG11 improves drought tolerance of transgenic rice. A, Drought treatment of 3-week-old T3 transgenic seedlings in greenhouse. a, Before drought treatment. b, Drought for 5 d. c, Drought for 9 d and then recovery for 3 d. d, Drought for 9 d and then recovery for 8 d. B, Survival after 9 d of drought treatment and 8 d of recovery. Values are mean ± sd (n = 27 plants, ***P < 0.001). C, The appearance of transgenic plants and ZH11 control during drought stress at flowering stage in the greenhouse. Plants in same size containers were treated without water for 5 d. D, Water loss rate of detached flag leaves. Each data point represents the mean of duplicate measurements.
