Drought tolerance of AtCSP3-overexpression lines. (A) Phenotype of AtCSP3-overexpressing plants after re-watering. Plants were grown in separate pots (one plant per pot) and drought-stressed by withholding water for 10 d. The photograph was taken 1 d after re-watering. Note that pots were rearranged to better show the differences between genotypes. Survivors are surrounded by lines. (B) Survival rates and standard deviations were calculated from three independent experiments (n = 48). Asterisks indicate significantly higher survival compared to wild-type (WT) as determined by Student's t test (**P < 0.01).
