CCD1 — Phaseolus vulgaris

Summary

PHAVU_011G211200, designated PvCCD1 (also known as PvNCED1), encodes a carotenoid dioxygenase with 9-cis-epoxycarotenoid dioxygenase activity and metal binding, belonging to the Carotenoid_Oase family. In French bean (Phaseolus vulgaris) on chromosome 11, this gene is associated with carotenoid, xanthophyll, carotene, and lycopene metabolism, abscisic acid biosynthesis and signaling, and responses to salicylate, gibberellin, auxin, and salinity. It is linked to seed maturation, anther and pollen development, fruit ripening, and localizes to the vacuole, plasmodesmata, chloroplast stroma, Golgi, cytosol, and plasma membrane. Associations include seedling vigor, germination rate, stem length, protein content, drought tolerance, seed carotenoid content and degradation, and ABA biosynthesis. Related genes in other species are linked to herbivore resistance, β-ionone emission, and carotenoid cleavage.
