LCY — Cucumis melo

Summary

MELO3C020744.2, designated CmLCY on melon chromosome 9, encodes a protein with lycopene beta-cyclase, capsanthin synthase, capsorubin synthase and neoxanthin synthase activities, and belongs to the lycopene cyclase b/e and FAD/NAD-binding superfamilies. The gene is associated with beta-zeacarotene, beta-carotene, carotene, xanthophyll, ubiquinone, and abscisic acid anabolism, carotenoid metabolism, nitric oxide storage, and fruit ripening. It is linked to chromoplast and chloroplast membranes, plastids, and mitochondria. Associations include beta-carotene and carotene content, fruit weight and size, respiration rate, and ethylene sensitivity. Studies of related genes in other species connect the family to carotenoid accumulation, photosynthetic efficiency, biomass production, abiotic stress tolerance, and fruit color and development.
