LCY — Brassica oleracea var. botrytis

Summary

BoLCY (LCY) on cauliflower chromosome 5 encodes a lycopene cyclase domain protein with capsorubin synthase, capsanthin synthase, lycopene beta-cyclase, neoxanthin synthase, and oxidoreductase activities. It is associated with beta-carotene metabolism, beta-zeacarotene anabolism, carotene metabolism, carotene anabolism, beta-carotene anabolism, carotenoid metabolism, xanthophyll anabolism, ubiquinone anabolism, abscisic acid anabolism, carotenoid anabolism, and nitric oxide storage. The protein localises to chromoplast and chloroplast membranes, plastids, and mitochondria. BoLCY is linked to leaf curling and carotenoid content, and to photosystem I photoprotection and partial restoration of non-photochemical quenching defects with decreased rosette size. Related genes in other species connect the family to altered carotenoid composition, albino seeds, and salt tolerance.
