CC   -!- FUNCTION: Probably involved in the disassembling mechanism of the
CC       intact light-harvesting complex of photosystem II (LHCII) in the
CC       thylakoid membranes. Required for the chlorophyll breakdown pathway.
CC       Acts independent and upstream of pheophorbide a oxygenase (PAO).
CC       {ECO:0000269|PubMed:17709752, ECO:0000269|PubMed:18301989}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast
CC       {ECO:0000269|PubMed:17709752}.
CC   -!- DEVELOPMENTAL STAGE: Strongly induced during senescence.
CC       {ECO:0000269|PubMed:18301989}.
CC   -!- INDUCTION: Up-regulated during dark-induced senescence.
CC       {ECO:0000269|PubMed:17709752}.
CC   -!- MISCELLANEOUS: Corresponds to one of the seven genes studied by Gregor
CC       Mendel in 1866 (PubMed:17204643). The green cotyledon (i) line JI2775
CC       used in the original work has a non-functional SGR protein (AC A7VLV2)
CC       due to the presence of a two amino acids insertion (PubMed:17709752 and
CC       PubMed:18301989). {ECO:0000305|PubMed:17204643}.
CC   -!- SIMILARITY: Belongs to the staygreen family. {ECO:0000305}.
