Relative expression levels detected by qRT-PCR under different hormone treatments including GA, IAA, ABA and ZT. The expression levels at 0 h were normalized to 1, and the Y-axis delineates the fold changes of relative expression comparing with 0 h. Bars represent the mean of three biological replicates ± SE. The two-fold threshold is presented by a dotted line. Values are presented relative to untreated plants (0 h). Asterisks indicate a significant difference (P < 0.05) between untreated and treated plants
