Induction was calculated as the average ratio of relative reporter gene activities (promoter-GUS/Ubi-LUC) between treatment and control (set to unity) from three- or four-paired replicates in two independent experiments.

↵F1-a Significantly higher than control,P < 0.03 (one-sided paired ttest).
↵F1-b Significantly higher than ABA treatment, P < 0.06 (one-sided paired ttest).
↵F1-c n/a, Not analyzed.
