a Heat map of differentially expressed transcripts belonging to secondary metabolism, with focus on flavonoid biosynthetic genes. b RT-qPCR expression profiles of genes encoding the main anthocyanin biosynthetic enzymes VvUFGT (VIT_16s0039g02230), VvAOMT (VIT_01s0010g03510), Vv3AT (VIT_03s0017g00870) and VvGST4 (VIT_04s0079g00690) analysed in leaf veins taken from healthy (H), recovered (REC) or FDp-infected (FD) ‘Barbera’ plants. Ubiquitin (VvUBI) and actin (VvACT1) genes were both used as endogenous controls for the normalisation of transcriptional levels. Lower case letters denote statistical differences when significant, as determined by Tukey’s HSD test (P < 0.05). Bars represent standard error of the mean (n = 5)
