Transcriptional profiles of selected genes in developing berries, grown in 2007-2008 (season 2). Error bars are standard errors of four biological replicates and three technical (qRT-PCR reaction) replicates. Transcriptional changes of V. vinifera genes: A. GDP-D-mannose-3,5-epimerase (GME), B. GDP-L-galactose phosphorylase (Vtc2). C. L-galactose dehydrogenase (L-GalDH), D. L-galactono-1,4-lactone dehydrogenase (GLDH), E. D-galacturonic acid reductase (GalUR), F. L-idonate dehydrogenase (L-IdnDH), G. monodehydroascorbate reductase (MDAR) and H. dehydroascorbate reductase (DHAR). The developmental stage of veraison is indicated by a grey dotted box.
