Gene expression of VvDFR, VvF3′H, VvF3′5′H1, and VvCytoB5 (TC45693) in grapes during the early stages of berry development, in seeds, and in berry skin. Flowering is marked by an arrow and occurred 8 weeks before véraison, which is the onset of ripening in grapes. Transcript levels were determined by real-time PCR and are shown relative to expression of VvUbiquitin1 in each sample. All data are presented as mean of three replicates.
