Basic information
Locus name	At4g11910
Alias	SGR2/NYE2
Organism	Arabidopsis thaliana
Taxonomic identifier	[NCBI]
Function category
Effect for Senescence	delay
Gene Description	NONYELLOWING 2/STAY-GREEN 2.Acts antagonistically with SGR1 to balance chlorophyll catabolism in chloroplasts with the dismantling and remobilizing of other cellular components in senescing leaf cells.
Evidence	Genetic evidence [Ref 1]

Mutant Image
SGR2-overexpressing plants stayed green and the sgr2-1 knockout mutant exhibited early leaf yellowing under age-, dark-, and stress-induced senescence conditions.
