IDD16‐OE plants exhibit enhanced water‐deficit stress tolerance that correlates with reduced water loss. (a) 16‐DAG well‐watered wild‐type, 35S:IDD16m and 35S:IDD16s plants (top panel) were withdrawn from irrigation for 11 days and then fully re‐watered. Pictures were taken at the indicated times. Experiments were repeated three times with the similar results. More than 60 plantlets for each genotype were used in each experiment. (b) Seedlings survival rates were determined 3 days after re‐watering. Data are from three independent experiments and shown as mean ± SE. (c) Tissue water loss. Aerial parts of 3‐week‐old well‐watered plants were detached, weighed immediately (0 min), allowed to dry under ambient conditions and weighed at the indicated times. Water loss was calculated as the percentage of the fresh weight at time zero. Values are means ± SE from four biological replicates. Asterisks indicate statistical significance based on Student's t test; ** P < 0.01, * P < 0.05.
