NCED2 — Daucus carota subsp. sativus

Summary

DCAR_003908 (NCED2, also known as NCED-6, DcNCED2, DcNCED3, DcNCED5, NCED3, or NCED5) on carrot chromosome 1 encodes an uncharacterized protein with a Carotenoid_Oase domain and is associated with carotenoid dioxygenase activity, 9-cis-epoxycarotenoid dioxygenase activity, and metal binding. The gene is associated with abscisic acid (ABA) anabolism, carotenoid and carotene breakdown, auxin anabolism, seed dormancy, fruit ripening, anther and pollen development, and responses to drought, salicylate, gibberellin, and auxin. It is linked to thylakoid and chloroplast stroma localisation. Associations include carotene content, photosynthetic rate, root length, high light stress tolerance, salt tolerance, seed germination, stomatal closure, resistance to Botrytis cinerea, drought tolerance, leaf senescence, and abiotic stress tolerance. Studies of related genes in other species connect the family to traits such as phosphorus content, lycopene content, root fresh weight, leaf water potential, and fruit firmness.
