- Key message
- RAI1 encodes a putative basic helix-loop-helix transcription factor
- In this study, we have identified RAI1 as the first transcription factor acting downstream of OsRac1
- The PAL1 and OsWRKY19 genes were also up-regulated by sphingolipid and chitin elicitors, and the RAI1 activation-tagged plants had increased resistance to a rice blast fungus
- These results indicated that RAI1 is involved in defense responses in rice
- In addition, we observed changes in RAI1 levels during blast infection, which led to identification of OsRPT2a, a subunit of the 19S regulatory particle of the 26S proteasome

- OsMKK4~LARGE11, RAI1, The bHLH Rac Immunity1 RAI1 Is Activated by OsRac1 via OsMAPK3 and OsMAPK6 in Rice Immunity, Also, RAI1 was phosphorylated by OsMAPK3/6 and OsMKK4-dd in vitro
- OsMKK4~LARGE11, RAI1, The bHLH Rac Immunity1 RAI1 Is Activated by OsRac1 via OsMAPK3 and OsMAPK6 in Rice Immunity, Therefore, the regulation of PAL1 and OsWRKY19 expression by RAI1 could be controlled via an OsMKK4-OsMAPK3/6 cascade
- OsMPK1~OsMAPK6~OsSIPK, RAI1, The bHLH Rac Immunity1 RAI1 Is Activated by OsRac1 via OsMAPK3 and OsMAPK6 in Rice Immunity, RAI1 interacted with OsMAPK3 and OsMAPK6 proteins in vivo and in vitro
- OsMPK1~OsMAPK6~OsSIPK, RAI1, The bHLH Rac Immunity1 RAI1 Is Activated by OsRac1 via OsMAPK3 and OsMAPK6 in Rice Immunity, The bHLH Rac Immunity1 (RAI1) Is Activated by OsRac1 via OsMAPK3 and OsMAPK6 in Rice Immunity

- OsRac1, RAI1, Importance of OsRac1 and RAI1 in signalling of NLR protein-mediated resistance to rice blast disease., We also identified RAI1, a transcriptional activator, as a PID3 interactor required for PID3-mediated blast resistance and showed that RAI1 expression is induced by PID3 via a process mediated by OsRac1
- OsRac1, RAI1, Importance of OsRac1 and RAI1 in signalling of NLR protein-mediated resistance to rice blast disease., This study describes a new signalling pathway for NLR protein-mediated blast resistance and shows that OsRac1 and RAI1 act together to play a critical role in this process
- OsRac1, RAI1, The OsSPK1-OsRac1-RAI1 defense signaling pathway is shared by two distantly related NLR proteins in rice blast resistance., OsSPK1 activates the small GTPase OsRac1, which in turn transduces the signal to the transcription factor RAC IMMUNITY1 (RAI1)
- OsSPK1, RAI1, The OsSPK1-OsRac1-RAI1 defense signaling pathway is shared by two distantly related NLR proteins in rice blast resistance., OsSPK1 activates the small GTPase OsRac1, which in turn transduces the signal to the transcription factor RAC IMMUNITY1 (RAI1)
