Summary of "Histochemical analysis of anthocyanin, carotenoids and flavan-3-ol/proanthocyanidins in L. fruits during ripening."

Due to the high variability of fruit properties in the European plum , a histochemical analysis of fruits at different stages of development was performed to understand the ripening process in the cv. 'Colora' (yellow-red skinned) and cv. 'Topfive' (purple skinned). Histological analysis showed that carotenoids in the fruit had two different origins. In the fruit flesh they derived from chloroplasts that turned into chromoplasts, whereas carotenoids in the fruit skin derived probably from proplastids. Flavan-3-ols and proanthocyanidins showed differential localization during ripening. They were visible in the vacuole in different fruit tissues or organized in tannosomes in the fruit flesh. Tanninoplast were observed only in hypodermal cells of 'Colora'. Towards maturity, anthocyanins were detected in the epidermis and later in the hypodermis of both cultivars. The study forms a basis for the analysis of the biosynthesis of secondary metabolites in European plums and their biological effects.
