MPK6 Contributes to Non-Host Resistance to Magnaporthe oryzae in Arabidopsis thaliana

Abstract

The rate of entry of Magnaporthe oryzae into pen2 mpk6 plants was higher than that into pen2 plants. The infection hyphae in the pen2 mpk6 plants were longer than those in the pen2 plants. The proportion of branched hyphae development in the pen2 mpk6 plants was higher than that in the pen2 plants. These results suggest that MPK6 functions in both penetration and post-penetration resistance to M. oryzae in Arabidopsis thaliana.
