a Morphological characteristics of GL-3, MdDof54 OE, and MdDof54 RNAi plants in response to short-term drought stress. Two-month-old plants were transplanted into soil for two additional months and then exposed to drought stress. After 34 days of drought stress, the plants were allowed to recover at saturated soil moisture for 7 days, after which the recovery results were obtained. Bars = 5 cm. b Survival percentage of plants shown in a after the recovery period. c–g Physiological changes in GL-3, MdDof54 OE, and MdDof54 RNAi plants after drought stress: ion leakage (c), peroxidase (POD) activities (d), superoxide dismutase (SOD) activities (e), catalase (CAT) activities (f), and ABA content (g). The asterisks indicate significant differences between the GL-3 and transgenic lines based on one-way ANOVA and Tukey′s test (*p < 0.05; **p < 0.01; ***p < 0.001). The error bars indicate standard deviations [n = 20 in b, 5 in c–g]. OE overexpression
