ERECTA contributes to non-host resistance to Magnaporthe oryzae in Arabidopsis

Abstract

ERECTA controls both developmental processes and disease resistance in Arabidopsis. We investigated the function of ERECTA in non-host resistance to Magnaporthe oryzae in Arabidopsis. In the pen2 er mutant, penetration resistance and post-penetration resistance to M. oryzae were compromised. These results suggest that ERECTA is involved in both penetration and post-penetration resistance to M. oryzae in Arabidopsis.

Key words:

• Arabidopsis
• ERECTA
• Magnaporthe oryzae
• non-host resistance
