| Research Abstract |
Plant pathogens have been rapidly evolving their strategy for infection and developing many virulence agents for perturbing host immune system. Thus, plants are constantly exposed to threats from pathogenic microbes in nature. On the contrary, subsets of microbes such as arbuscular mycorrhizal (AM) fungi or rhizobial bacteria symbiotically promote the host plant growth. How plants manage the acceptance of beneficial microbes while rejecting pathogens is a crucial question for understanding the plant-microbe interactions. However, this question has been rarely approached and the answer is still missing. Here, we report that a chitin receptor kinase, OsCERK1, engages in both triggering plant immune responses and acceptance of beneficial AM fungi in rice. These findings illuminate the presence of direct connection between plant defense and symbiotic mechanisms for the first time and are expected to be a breakthrough for this field.
