| Outline of Final Research Achievements |
In order to elucidate the regulatory system responsible for polyamine homeostasis and action, I focused on polyamine degradation enzyme, polyamine oxidase (PAO), and identified some kind of genes coding PAOs from Lotus corniculatus, Solanum lycopersicum and Brachypodium distachyon. These proteins catalyzed spermine to spermidine, or spermidine to putrescine. Moreover, it was found that defense-related gene’s expression is strongly induced by uncommon polyamines, homocaldopentamine and caldhexamine.
