  1. The data were acquired from the 3 week old plants treated by withholding irrigation for 3 weeks. Data represent the mean ± SE (n ≥ 15); similar results were obtained from three independent experiments. N: wild-type Col-0 suffered drought stress, and P: non-treatment wild-type Col-0. Significance of the phenotypic results was assessed using Student’s t tests (*P < 0.05, **P < 0.01).
