| Research Abstract |
Biocontrol agent, Pythium oligandrum (PO), has an ability to activate jasmonic acid (JA)-mediated induced resistance against pathogens in dicot plants. To elucidate the ability of PO in monocot plants, I studied the induction of defense gene expression in rice treated with PO, and the induced resistance to pathogens. The global gene expression analysis of the roots treated with the elicitor of PO indicated that the elicitor enhanced expression of JA-inducible genes. The expression of the JA-responsive defensive genes was also enhanced in hastened seeds treated with PO. Treatment of seeds with the oospore suspension following inoculation with a bacterial pathogen significantly reduced disease severity of the seedling rot as compared with an untreated control. These findings suggest that PO seems to activate JA signaling-mediated defense reaction and induce resistance against the infection of bacterial pathogens in rice.
