Fig. 7From: Genome-wide identification of small heat-shock protein (HSP20) gene family in grape and expression profile during berry developmentExpression profiles of VvHSP20s from qRT-PCR in the H2O2 treatment and the control. The x-axis represented different sampling date, while relative expression levels for the y-axis. Data represented the mean of three biological replicates. Error bars represented standard deviations from three independent technical replicates. And the expression level of K1 was used as the calibrator. The asterisks indicate the significant level (*P < 0.05, **P < 0.01) based on a Duncan’s multiple range testBack to article page
