| Outline of Final Research Achievements |
CERK1 is a LysM receptor kinase involved in the initiation of defense responses derived from carbohydrate ligand of bacterial and fungal cell walls. OsCERK1 is a bifunctional receptor, serving not only for the chitin/LPS-triggered defense response but also for arbuscular mycorrhizal (AM) symbiosis in rice, although the regulatory mechanism of these contradictory system is still unknown. In this study, we identified OsCERK2, which is structurally and functionally similar to OsCERK1. We found that the extra/intracellular region of CERK1 plays an important rule for the receptor complex formation to initiate the defense and symbiosis responses. We also indicated that several phosphorylation sites of AtCERK1 have critical function for the regulation of activation and downstream signaling.
