Fig. 6From: Genome-wide survey and expression analysis of GRAS transcription factor family in sweetpotato provides insights into their potential roles in stress responseRelative expression levels detected by qRT-PCR under different hormone treatments including ABA, ACC and JA. 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 lineBack to article page
