SGR — Pisum sativum

Summary

PSAT2G181040 (SGR) on pea chromosome 2LG1 encodes a Staygreen protein domain-containing protein. This gene is associated with pheophytinase activity, 7-hydroxymethyl chlorophyll A reductase activity, polyamine oxidase activity, RCC reductase activity, Chl b reductase activity, pheophorbide A oxygenase activity, chlorophyll b synthesis activity, Fe/S binding, chlorophyll binding, FAD or FADH2 binding, mRNA binding, and protein binding. It is associated with downregulation of chlorophyll breakdown, the chlorophyll cycle, polyamine breakdown, regulation of chlorophyll catabolic process, chlorophyll metabolism, nonphotochemical quenching, response to fructose, PSII associated light-harvesting complex II catabolic process, regulation of HR, photoprotection, regulation of programmed cell death, fruit development, protein breakdown, NO storage, embryogenesis, defense response to other organism, chloroplast organization, and seed development. The protein localizes to plastid thylakoid membrane, chloroplast inner membrane, chloroplast membrane, chloroplast thylakoid, thylakoid, chloroplast thylakoid membrane, chloroplast envelope, apoplast, and chloroplast stroma. SGR is also associated with leaf yellowing tolerance, hybrid incompatibility, yield trait, cytokinin sensitivity, cotyledon morphology trait, light intensity response, seed maturation, chlorophyll content, leaf senescence trait, abscisic acid sensitivity, disease tolerance, salt tolerance, root morphology trait, gravity
