Expression profile of V. vinifera AP2 and RAV genes. The expresssion of all AP2 and RAV 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.
