Figure 4From: Reciprocity between abscisic acid and ethylene at the onset of berry ripening and after harvestThe expression of VvACO1, VvETR2 , VvCTR1 and VvEIN4 during grape berry development of Muscat Hamburg ( Vitis vinifera L.). Real-time RT-PCR was performed on total RNA isolated from pulp, and VvACT was used to standardize each reaction run with respect to RNA integrity, and inter-PCR variations. Expression of each gene is presented as relative fold change. The experiments were repeated 3 times, and the bars represent SE (n ≥ 3).Back to article page
