Abstract: Black- and white-berried grapevine cultivars are distinguished by their ability to accumulate anthocyanins in the berry skin. To assess possible side effects of color variation in berry development and composition in a near-isogenic background, we compared white-berried somatic variants (WV) to their black-berried ancestors in ‘Garnacha’ and ‘Tempranillo’ cultivars. Absence of anthocyanins correlated with lower berry temperature during daytime in WV. At the transcriptome level, besides genes related to anthocyanin accumulation, transcri...
