Outline of Final Research Achievements

In this study, we performed comparative expression analysis by using RNA-Seq and RT-qPCR methods in the petals of morning glory and revealed that transcription factor gene, InNAP, and ethylene-related genes were associated with the strain difference of flower longevity. We also confirmed that several genes involved in the control of petal senescence by using transgenic plants which reduced expression of 14-3-3 protein gene, InPSR42. In addition, we detected dark-responsive genes, DR03 and DR11, involved with the determination of petal opening time of morning glory by SSH methods.
