General annotation (Comments)

Function

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). Ref.1 Ref.2

Subcellular location

Plastidchloroplast Ref.1.

Developmental stage

Strongly induced during senescence. Ref.2

Induction

Up-regulated during dark-induced senescence. Ref.1

Miscellaneous

Correspond to one of the seven genes studied by Gregor Mendel in 1866 (Ref.3). 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 (Ref.1 and Ref.2).

Sequence similarities

Belongs to the staygreen family.
