- Key message
- Cooperative regulation of PBI1 and MAPKs controls WRKY45 transcription factor in rice immunity.
- In addition, chitin-induced MAP kinase activation is required for WRKY45 activation and PBI1 degradation
- PBI1 also interacts with WRKY45, a master transcriptional activator of rice immunity, and negatively regulates its activity
- These data suggest that PBI1 suppresses WRKY45 activity when cells are in an unelicited state, and during chitin signaling, PUB44-mediated degradation of PBI1 leads to activation of WRKY45
- Cooperative regulation of PBI1 and MAPKs controls WRKY45 transcription factor in rice immunity

- OsWRKY45~WRKY45, PBI1, Cooperative regulation of PBI1 and MAPKs controls WRKY45 transcription factor in rice immunity., These results demonstrate that chitin-induced activation of WRKY45 is regulated by the cooperation between MAP kinase-mediated phosphorylation and PUB44-mediated PBI1 degradation
- OsPUB44, PBI1, Cooperative regulation of PBI1 and MAPKs controls WRKY45 transcription factor in rice immunity, PBI1 is degraded upon perception of chitin, and this is suppressed by silencing of PUB44 or expression of XopP, indicating that PBI1 degradation depends on PUB44.
