Basic mutant information
Mutant name	ore4-1
Mutant/Transgenic	mutant
Ecotype	Col-0
Mutagenesis type	T-DNA insertion_knock out
(Semi-)Dominant/Recessive	recessive
Description	The mutation, termed ore4-1, delays a broad spectrum of age-dependent leaf senescence, but has little effect on leaf senescence artificially induced by darkness.
