CC   -!- FUNCTION: Non-functional protein probably interfering with the
CC       disassembling mechanism of the intact light-harvesting complex of
CC       photosystem II (LHCII) in the thylakoid membranes. Responsible for a
CC       stay-green phenotype. {ECO:0000269|PubMed:18301989, ECO:0000269|Ref.1}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000269|Ref.1}.
CC   -!- DEVELOPMENTAL STAGE: Not induced during senescence.
CC       {ECO:0000269|PubMed:18301989}.
CC   -!- INDUCTION: Up-regulated during dark-induced senescence.
CC       {ECO:0000269|Ref.1}.
CC   -!- MISCELLANEOUS: Corresponds to one of the seven genes studied by Gregor
CC       Mendel in 1866 (PubMed:17204643). The wild type line JI4 has a
CC       functional SGR protein (AC A7VLV1) lacking a two amino acids insertion.
CC       This protein is involved in the chlorophyll breakdown pathway (Ref.1
CC       and PubMed:18301989). {ECO:0000305|PubMed:17204643}.
CC   -!- SIMILARITY: Belongs to the staygreen family. {ECO:0000305}.
