Drought survival and leaf water loss analysis in HD2 overexpression lines. (A) Images of WT and HD2-OE plants under control and two days after rewatering, following 13 days of drought stress. (B) Survival rates of WT, HD2A, and HD2C overexpression lines after drought stress. Data shown are means ± standard errors (n = 3) from three independent experiments. In each experiment, at least 30 plants of each genotype were used to calculate the survival. The significance of the differences between different genotypes was determined by one-way ANOVA followed by post-hoc Tukey’s HSD tests. Lowercase letters indicate significant differences (p < 0.01). (C, D) Fresh leaf water loss measured in HD2A-OE (C) and HD2C-OE (D) plants at every 30-minute interval for the period of 180 minutes. Data shown are means ± standard errors (n = 3) from three independent experiments. In each experiment, measurements were taken from three plants (three leaves per plant).
