This coincides with the findings of Boss et al. [2]. In the white-skin sports White Cabernet and Pinot Blanc, UFGT gene expression was not detected, while the other anthocyanin biosynthetic genes were expressed. They also found that the red-skin sport Red Chardonnay recovered the expression of the UFGT gene, which was not detected in the progenitor of the sport, white-skinned Chardonnay. Another red-skin sport Pink Sultana recovered the expression of many anthocyanin biosynthetic genes, which were not detected in Sultana.
