Mango fruit is cherished by masses for its taste and nutrition, contributed by color, flavor, and aroma. Among these,
peel color is an important trait contributing to fruit quality and market value. We attempted to elucidate the role of key genes
of the anthocyanin biosynthesis pathway related to fruit peel color from the leaf transcriptome of mango cultivar Amrapali. A
total of 108 mined transcript sequences were assigned to the phenylpropanoid–flavonoid pathway from which 15 contigs
representing anthocyanin biosynthesis genes were annotated. Alternate splice variants were identified by mapping against
genes of Citrus clementina and Vitis vinifera (closest relatives) and protein subcellular localization was determined. Phylogenetic
analysis of these pathway genes clustered them into distinct groups aligning with homologous genes of Magnifera indica,
C. clementina, and V. vinifera. Expression profiling revealed higher relative fold expressions in mature fruit peel of red-colored
varieties (Arunika, Ambika, and Tommy Atkins) in comparison with the green-peeled Amrapali. MiCHS, MiCHI, and MiF3H
alternate splice variants revealed differential gene expression. Functionally divergent variants indicate availability of an allelic
pool programmed to play critical roles in peel color. This study provides insight into the molecular genetic basis of peel color and
offers scope for development of biomarkers in varietal improvement programs.
