Outline of Final Research Achievements

Non-host resistance (NHR) to Magnaporthe oryzae has two successive multicomponent defense layers: penetration and post-penetration resistance in Arabidopsis thaliana. In this study, we showed that MPK6 functions in penetration resistance to M. oryzae in A. thaliana. We also showed that AGB1, PMR5, MLO2, MPK6 and AtRbohF function in post-penetration resistance in A. thaliana. Furthermore, we found that rice Pi21 enhances movement of infection hyphae from penetrated A. thaliana epidermal cells to adjacent mesophyll cells.
