Transcription factors (TFs) play essential roles in transcriptional reprogramming during activation of plant immune responses to pathogens. OsSPL10 (SQUAMOSA promoter binding protein-like10) is an important TF regulating trichome development and salt tolerance in rice. Here we report that knockout of OsSPL10 reduces whereas its overexpression enhances rice resistance to blast disease. OsSPL10 positively regulates chitin-induced immune responses including reactive oxygen species (ROS) burst and callose deposition. We show that OsSPL10 physically associates with OsJAmyb, an important TF involved in jasmonic acid (JA) signaling, and positively regulates its protein stability. We then prove that OsJAmyb positively regulates resistance to blast. Our results reveal a molecular module consisting of OsSPL10 and OsJAmyb that positively regulates blast resistance. |
