| Outline of Final Research Achievements |
Currently, it has been known that plant NLR type immune receptors have integrated domains (IDs) derived from other host proteins. Some reports showed that IDs bind to pathogen effectors and enable NLRs to recognize pathogen effectors, directly. Therefore, IDs are regarded as important information to understand host-pathogen interactions.
In this study, we found the ID of rice NLR, Pii, and showed that the Pii-ID did not contribute to direct binding to cognate fungal effector, AVR-Pii. On the other hand, Pii-ID had crucial roles in the interaction with OsExo70-F3, an AVR-Pii-interactor required for Pii-dependent resistance, and in the recognition of AVR-Pii. These results indicate that Pii-ID may function by detecting host accessory protein targeted by pathogen effectors. This finding is different from the known ID function as pathogen effector-interacting domain, and may expand speculated functions of NLR-ID.
