SGR — Brassica oleracea

Summary

BoSGR (BOLC102_C03P090650.1) on cabbage chromosome 3 encodes a Staygreen family protein. It is annotated with pheophytinase, RCC reductase, Chl b reductase, 7-hydroxymethyl chlorophyll a reductase, pheophorbide a oxygenase, and polyamine oxidase activities, along with chlorophyll, Fe/S, FAD, mRNA, and protein binding. It is associated with the chlorophyll cycle, chlorophyll catabolic process regulation, PSII light-harvesting complex II catabolism, programmed cell death regulation, defense response, fruit and flower development, ABA signaling, and chloroplast organization. Localized to chloroplast membranes, thylakoids, envelope, stroma, and apoplast, BoSGR is linked to the stay-green trait, leaf yellowing tolerance, chlorophyll content, leaf senescence, yield, flavonoid content, salt and drought tolerance, disease tolerance, abscisic acid and cytokinin sensitivity, root and cotyledon morphology, and hybrid incompatibility.
