LCYB — Nicotiana attenuata

Summary

A4A49_32107 (NaLCYB, LCYB) in coyote tobacco (Nicotiana attenuata) encodes a protein with a FAD/NAD-binding domain superfamily. The gene is associated with carotenoid anabolism, pigmentation, photoprotection, plastid localization, secondary metabolism, RNA metabolism, NO storage, and seed germination. It has been linked to carotene and carotenoid content, leaf size, root length, plant height, and salt tolerance, as well as nonphotochemical quenching. Studies of related genes in other species connect the family to lutein, beta-carotene, lycopene, abscisic acid, and chlorophyll content, fruit firmness, color, and shelf life, photochemical quenching, drought tolerance, and carotenoid biosynthesis, including beta-carotene accumulation.
