LCYB — Daucus carota subsp. sativus

Summary

DCAR_019750, symbol LCYB and preferred name DcLCYB, encodes a protein containing a FAD/NAD-binding domain superfamily. In carrot (Daucus carota subsp. sativus) on chromosome 5, this gene is associated with carotenoid metabolism, pigment accumulation, photoprotection, plastid localization, RNA metabolism, post-transcriptional gene silencing, secondary metabolism, and nitric oxide storage. It has been linked to carotene and carotenoid content, leaf size, plant height, drought tolerance, salt tolerance, and nonphotochemical quenching. Studies of related genes in other species connect the LCYB family to beta-carotene and lutein content, lycopene content, abscisic acid content, fruit firmness, fruit color, root length, chlorophyll content, photochemical quenching, and fruit shelf life.
