Protein

Protein STAY-GREEN, chloroplastic

Gene

SGR

Organism
Pisum sativum (Garden pea)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Probably involved in the disassembling mechanism of the intact light-harvesting complex of photosystem II (LHCII) in the thylakoid membranes. Required for the chlorophyll breakdown pathway. Acts independent and upstream of pheophorbide a oxygenase (PAO).2 Publications

Miscellaneous

Corresponds to one of the seven genes studied by Gregor Mendel in 1866 (PubMed:17204643). The green cotyledon (i) line JI2775 used in the original work has a non-functional SGR protein (AC A7VLV2) due to the presence of a two amino acids insertion (PubMed:17709752 and PubMed:18301989).1 Publication
