NCED3 — Oryza sativa Indica Group

Summary

BGIOSGA015823 (NCED3) on chromosome 4 of Indica rice encodes an uncharacterized protein with carotenoid dioxygenase activity and 9-cis-epoxycarotenoid dioxygenase activity and metal binding, placing it in the Carotenoid_Oase domain family. The gene is associated with abscisic acid (ABA) anabolism and signaling, carotene breakdown, lycopene and beta-carotene anabolism, the ascorbate-glutathione cycle, and responses to salinity, thirst, auxin, gibberellin, and salicylate. It is linked to anther and pollen development, fruit ripening, detoxification, and homeostasis. The product localizes to the chloroplast thylakoid membrane and stroma. Trait associations include abscisic acid content, grain length, grain size, chlorophyll content, and salt stress response. Related genes in other species are linked to seed maturation and dormancy.
