Transcript abundances of eight potential ripening indicators in Vitis vinifera cv. Cabernet Sauvignon. The expression profiles of VvCCD4a (A), VvPAL2 (B), VvGolS (C), VvLEA1 (D), VvDIR-like (E), VvHKR (F), VvValCS (G) and VvSAMT (H) were investigated from véraison to harvest. Berries were subjected to either 30°C days and 25°C nights or 20°C days and 15°C nights temperature regimes. The mRNA level was expressed relative to the lowest level of expression detected in any sample for each gene, reference genes Ubiquitin, Actin and EF1-α. RT-PCR data are reported as means ± SE (error bars) of n = 3 technical replicates.
