Basic mutant information   
Mutant name rpk1-4
Mutant/Transgenic mutant
Ecotype Col-0
Mutagenesis type Ds insertion
(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.
