PDS — Daucus carota subsp. sativus

Summary

DCAR_016085 (PDS) on carrot chromosome 5 encodes a protein with zeta-carotene desaturase and amine oxidase domains, and is annotated with 9,9'-di-cis-zeta-carotene desaturase activity, phytoene dehydrogenase activity, and FAD binding. The gene is associated with carotene, lycopene, and carotenoid anabolism, photoprotection, photomorphogenesis, root development, and response to herbicide. It localizes to plastid membranes, chloroplast thylakoids and envelope, and cytosol. Associations include root color, respiration rate, ethylene sensitivity, photosynthetic rate, albino phenotype, fruit pigmentation, phytoene desaturation, chlorophyll biosynthesis, and lateral root and primary root growth. Studies of related genes in other species link the family to carotenoid content, leaf pigmentation, photobleaching, chilling injury resistance, drought tolerance, and insect resistance.
