CCD1 — Brassica oleracea var. botrytis

Summary

BoCCD1, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with a Carotenoid_Oase domain and exhibits 9-cis-epoxycarotenoid dioxygenase and carotenoid dioxygenase activities, along with metal binding. This gene is associated with carotenoid, xanthophyll, and carotene breakdown, as well as the anabolism of lycopene, beta-carotene, xanthophyll, and abscisic acid. It is linked to anther and pollen development, fruit ripening, cell death, ABA signaling, and responses to salicylate, gibberellin, auxin, and thirst. The product localizes to the plant-type vacuole, chloroplast stroma, plasmodesma, Golgi complex, cytosol, plasmalemma, and cytoplasm. Associations include seed carotenoid content and degradation, and abscisic acid biosynthesis. Related genes in other species link the family to herbivore resistance, β-ionone emission, and carotenoid cleavage.
