Genes from the phenylpropanoid metabolic pathways whose expression was significantly altered by GRBaV infections in both vineyards
Functional annotations and gene accessions are provided, in addition to their fold changes in expression when comparing GRBaV-positive (+) versus negative (–) berries. All reported changes correspond to significant up- or down-regulation (P≤0.05).
