FIGURE 2.

The drought tolerance of transgenic tobacco seedlings with drought-inducible expression of TaFBA1 and WT. (A) Seed germination on filter paper containing 0 (CK), 15 and 20% PEG6000. (B) Germination rate (%) of RD29A::TaFBA1 and WT seeds in (A). Germination rate was scored every day and the final result at 7 days after germination was presented. (C,D) Survival rates of transgenic and WT plants after withholding water for 10 days (Treatment of drought) and then rehydration for 3 days (Rewatered). The survival rate was scored according to the rewatered plants. The experiments were repeated three times. Each column represents the average of at least three replicates ± standard error (SE). “^∗” and “^∗∗” indicates significant differences compared with WT at P < 0.05 and P < 0.01.
