Expression of ABA-responsive genes in wrky6 mutants and WRKY6-overexpressing lines.

The imbibed seeds were germinated and grown on MS medium for 7 d, and then the seedlings were harvested for qRT-PCR. Data are shown as mean ± SE (n = 3). Asterisks indicate statistically significant differences compared with wild-type plants: *, P 0.05; **, P 0.01. Wild-type plant (WT) was used as a control (#).
