Dinitrogen pentoxide (N₂O₅) is promising for various applications owing to its unique reactivity. But it has rarely reported in applied research due to the difficulties of its synthesis and storage. Recently, we have developed a new technique, which can electrically generate N₂O₅ using atmospheric pressure plasma from air with high safety and easy handling. In this presentation, we will discuss the plant immune activation effect of N₂O₅ gas exposure supported from the experimental results of initial Ca²⁺ response, expression of plant defense related genes, and pathogen inoculation tests.
