FIGURE 3.

Overexpression of AtUGT76C2 increased the plant sensitivity to abscisic acid (ABA) during germination and post-germination growth. (A) Rice seeds were imbibed at 28°C in hydroponic solution with 2 μM ABA (dissolved with little ethonal) and without ABA (Mock, with equal amount of ethonal). Germination (based on radicles>2 mm) of at least 50 seeds were recorded for each biological replicates, and three biological replicates were done for calculating germination rates (B). Post-germination growth of the seedlings under ABA, and shoot lengths were recorded. Bars show standard deviations of three independent replicates. Asterisks indicate significant differences between the wild type and the overexpression lines evaluated with Student’s t-test (**P < 0.01).
