Our group studies arbuscular mycorrhizal (AM) symbiosis. AM symbiosis started shortly after plant terrestrialization and is currently conserved in more than 70% of land plants. The elucidation of AM symbiosis is important for understanding plant physiology, ecology, and evolution. We aim to understand how plants and AM fungi find and recognize each other and focus on the signaling molecules. We are also trying to establish new fundamental experimental systems for AM symbiosis research, including axenic culture and transfection.
