Expression profile of V. vinifera ERF genes, subdivided into groups (I-X). The expression of all ERF genes identified in this study was measured by RT-qPCR in aerial vegetative (leaves and stems) and reproductive (inflorescence, berry skin and berry flesh) tissues. For berry and skin tissues two developmental stages (veraison and full ripeness) were analyzed. The relative expression value was calculated according to the formula CtHK-CtGene. The results shown are from at least three independent replicates. Hierarchical clustering was used to represent the gene expression within each family.
