CCR2 — Cucumis melo

Summary

MELO3C009571.2 (symbol CmCCR2, also known as CmCRTISO-1) on melon chromosome 5 encodes a carotenoid isomerase (EC 5.2.1.13) with redox activity, belonging to the CrtISO-like and amine oxidase domain families. The gene is associated with carotenoid metabolism and anabolism, etioplast organization, and localization to the chloroplast membrane. It has been linked to fruit color, carotene and carotenoid content, respiration rate, plastid development, and carotenoid composition. Studies of related genes in other species connect the family to diverse traits including fruit weight and size, grain dimensions, plant height, flower and leaf color, lycopene and anthocyanin content, chlorophyll accumulation, drought tolerance, photomorphogenesis, and prolamellar body formation.
