Research Abstract

Polyamines are important not only for developmental processes but also for various environmental stress responses in plants. In order to elucidate the regulatory system responsible for polyamine homeostasis and action, I focused on polyamine degradationenzyme, polyamine oxidase (PAO), and identified three different genes coding for main PAOs in rice. These proteins were localized to peroxisomes and catalyzed polyamine back conversion. Moreover, it was found that one of the common tetraamines, thermospermine, is involved in disease resistance as a signal molecule like spermine.
