Fig. 3. MdSE transgenic plant response to drought stress.
a, f Drought tolerance of GL-3 and transgenic plants. Bars = 5cm. Five-month-old MdSE OE and GL-3 plants were treated with drought for 24 days, and then rewatered for 7 days. MdSE RNAi and GL-3 plants were treated with drought for 30 days, and then rewatered for 7 days. b, g Survival rate of GL-3 and transgenic plants shown in a and f. Data are means ± SD (n = 36). c, h Water loss of GL-3 and MdSE OE or RNAi plants under dehydration conditions for up to 360 min. Data are means ± SD (n = 10). d, i The rate of photosynthesis (AN). e, j Intrinsic water use efficiency (WUEi). Data are means ± SD (n = 15). Student’s t test was performed, and statistically significant differences are indicated by *P < 0.05, **P < 0.01, or ***P < 0.001
