TaTIP4;1 overexpression improved drought tolerance in Arabidopsis. (A) Growth performances of plants. Four-week-old plants of Arabidopsis WT, VC, OE6, OE9 and OE10 were not watered for 2 and 4 weeks, respectively, and then rewatered for 1 week. (B) The survival rates of plants after drought stress for 4 weeks. (C) Relative water contents of leaves after drought stress for 4 weeks. Different lowercase letters show that the values from the plants significantly differed from each other by one way ANOVA and Tukey’s honestly significant difference test (Tukey’s HSD test) (p < 0.05). (D) Leaf water loss rates of four-week-old plants. Single and double asterisk indicate that the values of TaTIP4;1 overexpressors significantly differed from WT and VC plants at * p < 0.05 and ** p < 0.01 levels respectively by student’s t test. Data are mean ± SD (n ≥ 3).
