CCD4 — Daucus carota subsp. sativus

Summary

DCAR_030904, the carrot gene DcCCD4 on chromosome 9, encodes an uncharacterized protein with a carotenoid oxygenase domain and is annotated with carotenoid dioxygenase activity and 9-cis-epoxycarotenoid dioxygenase activity, metal binding, and mRNA and protein binding. It is associated with carotenoid, beta-carotene, and carotene breakdown, as well as abscisic acid anabolism, anther and pollen development, fruit ripening, response to salicylate and gibberellin, chloroplast organization and mRNA modification, and NO storage. The gene is linked to taproot color, carotenoid content, chlorophyll content, chloroplast development, salt tolerance, heat sprouting, tuber morphology and carotenoid content, leaf development and senescence, seed beta-carotene content, and apocarotenoid signaling. It localizes to the chloroplast stroma, cytosol, and nucleus, and is connected to strigolactone-mediated bud dormancy, shoot gravitropism, and abiotic stress responses.
