Basic mutant information
Mutant name	rpk1-4
Mutant/Transgenic	mutant
Ecotype	Col-0
Mutagenesis type	Ds insertion;T-DNA
(Semi-)Dominant/Recessive	recessive
Description	Loss-of-function mutants in RPK1 were significantly delayed in age-dependent senescence. Furthermore, rpk1 mutants exhibited reduced sensitivity to ABA induced senescence but little to jasmonic acid- or ethylene-induced senescence. RPK1 thus mediates ABA-induced leaf senescence as well as age-induced leaf senescence.
