Responses of wild type WT and transgenic Arabidopsis plants expressing BnaABF2 to drought and salt stresses. a Expression levels of BnaABF2 gene in WT, BnaABF2-2, BnaABF2-11 and BnaABF2-15 transgenic lines. ACTIN2 was used as a loading control. b Two-week-old WT and transgenic plants were well watered (Control) or deprived of water for 2 weeks and then rewatered (Drought). The photos were taken on day 1 after rewatering. c Survival rates of 4-week-old WT and transgenic plants on day 1 after rewatering. d Two-week-old WT and transgenic plants grown in soil under normal conditions (Control) or following salt treatment for 2 weeks (300 mM NaCl). e Survival rates of 4-week-old WT and transgenic plants after salt stress in soil. Values are mean ± SE from three independent experiments (n = 50). *, P < 0.01 compared with WT in the same treatment
