We use to think that grapes are only black or white. It’s a mistake. In nature, there are grapevine varieties with bunches of different shades, ranging from salmon to lilac, through gray, red and dark purple, up to almost black. Anthocyanin pigments are responsible for these nuances. Dysfunctions in the biosynthetic pathway of these compounds lead to determine the different colors. In this study, the genetic anomalies related to the chromatic variability of 15 pink berry grapevine varieties were identified, through an innovative targeted resequencing technique. The aim is to support the wine sector in the selection of pink berry table grapes, particularly appreciated by consumers.
