Quantitative RT-PCR analysis of the VvbZIP gene expression in grapevine leaves (sequenced genotype, PN40024) in response to drought stress and 45°C heat stress. The normalized relative expression level of the 0 d treatment timepoint was set up as 1. The y-axis indicates the relative folds of gene expression compared with the control. Leaves collected at 0, 4, 8 and 12 d post-drought or at 0, 2, 5 h post heat stress and 24 h recovery. Means are calculated from technical triplicate qRT-PCR measurements within three biological replicates.
