摘要： The crosstalk between brassinosteroid (BR) and jasmonic acid (JA) signaling is crucial for plant growth and defense responses. However, the detailed interplay between BRs and JA remains obscure. Here, we found that the rice (Oryza sativa) Glycogen synthase kinase3 (GSK3)-like kinase OsGSK2, a conserved kinase serving as a key suppressor of BR signaling, enhanced antiviral defense and the JA response. We identified a member of the JASMONATE ZIM-domain (JAZ) family, OsJAZ4, as a OsGSK2 substrate and confirmed that OsGSK2 interacted with and phosphorylated OsJAZ4. We demonstrated that OsGSK2 disrupted the OsJAZ4-OsNINJA complex and OsJAZ4-OsJAZ11 dimerization by competitively binding to the ZIM domain, perhaps helping to facilitate the degradation of OsJAZ4 via the 26S proteasome pathway. We also showed that OsJAZ4 negatively modulated JA signaling and antiviral defense and that the BR pathway was involved in modulating the stability of OsJAZ4 protein in anOsCORONATINE INSENSITIVE1-dependent manner. Collectively, these results suggest that OsGSK2 enhances plant antiviral defenses by activating JA signaling as it directly interacts with, phosphorylates, and destabilizes OsJAZ4. Thus, our findings provide a clear link between BR and JA signaling. OsGSK2 directly interacts with and destabilizes OsJAZ4 to activate JA-mediated defense signaling.
