| Research Abstract |
In this study, we evaluated effects of knockout of petal senescence-relatedgenes, InVPE, InPSR26, InPSR29 and InPSR42, using RNAi method on petal senescence and showedthat two genes of them, InPSR26 and InPSR29, are carrying out a function to suppress senescence in thepetals of Japanese morning glory. The function of the other two genes, InVPE and InPSR42, could notbe clarified, but homology search of these genes suggested that they are deeply related to theprogrammed cell death in the petals of morning glory.
