LCY — Capsicum annuum

Summary

T459_13595 (LCY, LCY1) on pepper chromosome 5 encodes a protein with capsanthin synthase, capsorubin synthase, lycopene beta cyclase, neoxanthin synthase, intramolecular isomerase, cyclase, oxidoreductase, and redox 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, abscisic acid, carotenoid, and chlorophyll anabolism, the MEP pathway, photoprotection, chlorophyll fluorescence, virus-induced PTGS, and fruit ripening. It localises to chromoplast, chloroplast and mitochondrial membranes and plastids. Associations include fruit color, size and type, lutein content, respiration rate, ethylene sensitivity, leaf shape, plant height, flowering time, biomass, and photosystem I photoprotection. Related genes in other species are linked to carotenoid accumulation, pigment content, antioxidant activity, photosynthetic efficiency, biomass production, yield, and abiotic stress tolerance.
