Responses of WT and the transgenic plants to ABA. a Seeds were sown on MS medium supplemented with 0, 0.3, 0.5 or 1.0 μM ABA. Germination rates (%) were analyzed at day 2 after stratification. Values are mean ± SE from three independent experiments (n > 50 for each experiment). b Seedlings grew 7 days after transferred to MS medium supplemented with 0, 1, 10 or 50 μM ABA. Seedlings were transferred from ABA-free medium to ABA-containing medium 4 days after stratification. Scale bar = 1 cm. c Primary root lengths were assayed at day 7 after transfer. Values are the mean ± SE of three independent experiments (n = 30). *P < 0.05 compared with WT control
