Survival rates of wild-type (‘Columbia’), miz1-1 and MIZ1OE plants after treatment with 12-d drought stress. Fourteen-day-old plants were transplanted into moistened soil, and chambers were either entirely covered (Control) or were half-covered (Hydrostimulated) as shown in Fig. 1. Then, plants were grown without further water supply for 12 d. The plants were re-watered until soil water content reached >50 %, and the survival rate was counted 2 d after re-watering. Data are means ± s.e. (n = 21–29). Different letters above the bars indicate statistically significant differences at P < 0·05 by Tukey's HSD.
