| Outline of Final Research Achievements |
Priming plays an important role in plant defense. Priming state is induced by primary infection with pathogen and elicits strong resistance against secondary pathogen attack. Plant activator is chemical that induces the priming state in noninfected plants. Compared with bactericide and insecticide, plant activators have advantage of avoidance of drug-resistance pathogen and protection of microbes in the field.
We established a new high-throughput screening method to identify novel lead compounds for plant activator. From a total of 10,000 compounds screened, we selected 58 candidates for plant activator. The selected compounds enhanced the expression of defense-related genes in Arabidopsis. Furthermore, we examined the effects of the compounds on reactive oxygen species (ROS) production in SA biosynthesis or signal transduction mutants.
