Carotenoid Biosynthesis in Oriental Melon (Cucumis melo L. var. makuwa).

ABSTRACT: Full-length cDNAs encoding ξ-carotene desaturase (CmZDS), lycopene ε-cyclase (CmLCYE), β-ring carotene hydroxylase (CmCHXB), and zeaxanthin epoxidase (CmZEP), and partial-length cDNA encoding ε-ring carotene hydroxylase (CmCHXE) were isolated in Chamoe (Cucumis melo L. var. makuwa), an important commercial fruit. Sequence analyses revealed that these proteins share high identity and common features with other orthologous genes. Expression levels of entire genes involved in the carotenoid biosynthetic pathway were investigated in the peel, pulp, and stalk of chamoe cultivars Ohbokggul and Gotgam. Most of the carotenoid biosynthetic genes were expressed at their highest levels in the stalk, whereas carotenoids were highly distributed in the peel. The expression levels of all ca
