Basic mutant information   
Mutant name 35S:GRF5
Mutant/Transgenic transgene
Ecotype Col-0
Mutagenesis type transgenic
(Semi-)Dominant/Recessive dominant
Description 5S:GRF5 leaves are more sensitive to cytokinin-induced Chl retention during incubation in the dark, indicating that GRF5 overexpression potentiates the senescence-delaying effect of cytokinins.
