RT accumulation by interacting directly with SlPSY1 during ripening processes

CC -!- FUNCTION: Required to trigger chlorophyll degradation during leaf
CC senescence and fruit ripening (PubMed:18359841, Ref.3,
CC PubMed:23406468). Binds directly PSY1 to regulate the accumulation of
CC lycopene and beta-carotene in the maturing fruits (PubMed:23406468).
CC {ECO:0000269|PubMed:18359841, ECO:0000269|PubMed:23406468,
CC ECO:0000269|Ref.3}.
CC -!- SUBUNIT: Interacts with PSY1. {ECO:0000269|PubMed:23406468}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255}.
CC -!- DEVELOPMENTAL STAGE: Expressed during fruit ripening, but not during
CC fruit development (PubMed:18359841, Ref.3). Expressed during leaf
CC senescence, but not during leaf development (Ref.3).
CC {ECO:0000269|PubMed:18359841, ECO:0000269|Ref.3}.
CC -!- INDUCTION: Induced by drougt stress in leaves and stems.
CC {ECO:0000269|Ref.3}.
CC -!- MISCELLANEOUS: Plants silencing SGR1 exhibit a stay-green leaf
CC phenotype during leaf senescence, and a red-brown fruit phenotype in
CC mature fruit (Ref.3, PubMed:23406468). Plants silencing SGR1 exhibit
CC altered development of fruit pericarp cells (PubMed:23406468).
CC {ECO:0000269|PubMed:23406468, ECO:0000269|Ref.3}.
CC -!- SIMILARITY: Belongs to the staygreen family. {ECO:0000305}.
