Response of WT and transgenic lines to exogenous GA and ABA treatment. A Phenotype of WT and transgenic plants under normal conditions; B, C Phenotypes of 14-day-old seedlings of WT and transgenic lines under the treatment with exogenous 1 μM GA3 (B) and 3 μM ABA (C) for 7 days. D Relative elongation of plant height after 1 μM GA3 treatment for 7 and 14 days. E Relative elongation of plant height after 3 μM ABA treatment for 7 and 14 days. Data are shown as the means ± S.D. (n = 10). Significant differences (P < 0.05) are indicated by different letters
