Fig. 8From: Expansion and stress responses of the AP2/EREBP superfamily in cottonValidation the expression of the selected GhDREB/ERF genes inresponse to drought using qRT-PCR. The mean expression values were calculated from three independent replicates. 0, 1, 3, 6, 12 and 24Â h indicate the number of hours after treatment. Mean values and standard errors were calculated from three replicates. The asterisk and double asterisks represent significant differences at the levels of 0.05 and 0.01, respectively. R.e.l indicates Relative expression levelBack to article page
