  • Bud sports are infrequent changes in phenotype affecting shoots of woody perennials but the molecular basis of these mutations has rarely been identified. In this report, we show that the bronze-coloured berries of the Malian cultivar, a documented bud sport of the wine grape Cabernet Sauvignon (Vitis vinifera L.), lack anthocyanins in the subepidermal cells compared to the red/black berried Cabernet Sauvignon in which both the epidermis and several subepidermal cell layers contain anthocyanin… CONTINUE READING
