Expression of genes in chlorophyll degradation and anthocyanin biosynthesis in mango fruits. (a) Demonstration of peel colors of three representative mango varieties. Peel of developing fruit of Hongyu is green, while that of ripe fruit is yellow; peel of Guire-82 keeps green even when ripen; peel of Sensation demonstrates red color. (b) Expression of genes in chlorophyll degradation pathway in peel and flesh of Hongyu fruits as well as peel of Guire-82. (c) Expression of genes in anthocyanin biosynthesis in peel and flesh of Sensation fruits, as well as peels of Hongyu and Guire-82
