FIGURE 2.

Induction of ONAC022 expression by drought, salt, and abscisic acid (ABA). Two-week-old seedlings were exposed to drought (A), 150 mM NaCl (B), or treated by foliar spraying with 100 μM ABA (C) and leaf samples were collected at indicated time points for analyses of gene expression by qRT-PCR. Relative expression levels as compared to those of the actin gene at each time point are presented as the means ± SD from three independent experiments. ^∗Above the columns indicate significant differences at p ≤ 0.05 level with corresponding controls.
