NCED9 — Brassica oleracea var. botrytis
Summary
BoNCED9, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with 9-cis-epoxycarotenoid dioxygenase activity and carotenoid dioxygenase activity, and metal binding. This gene is associated with abscisic acid (ABA) anabolism and homeostasis, seed dormancy, fruit ripening, anther and pollen development, and responses to auxin, gibberellin, salicylate, salinity, and thirst. The gene product localises to the chloroplast thylakoid membrane and stroma. BoNCED9 is linked to susceptibility to Cauliflower mosaic virus, seed germination, and ABA biosynthesis. Related genes in other species connect the family to reduced seed dormancy, lower ABA levels, enhanced paclobutrazol resistance, and suppressed dark germination after far-red light, as well as to drought tolerance, seed longevity, and transpiration rate.
