- Key message
- Further results revealed that OsMKK4 influenced brassinosteroid (BR) responses and the expression of BR-related genes
- Among MAPK kinase (MKKs) gene family, OsMKK4 transcripts were found to be induced in arsenite treated rice leaves and roots
- Thus, our findings have identified OsMKK4 as a factor for grain size, and suggest a possible link between the MAPK pathways and BRs in grain growth
- Involvement of the OsMKK4-OsMPK1 Cascade and its Downstream Transcription Factor OsWRKY53 in the Wounding Response in Rice
- Taken together, components involving in the wounding signaling pathway, OsMKK4-OsMPK1-OsWRKY53, can be important players in regulating crosstalk between abiotic stress and biotic stress.
- Connection
- OsMKK4, OsMPK1~OsMAPK6~OsSIPK, The bHLH Rac Immunity1 RAI1 Is Activated by OsRac1 via OsMAPK3 and OsMAPK6 in Rice Immunity, Overexpression of OsMAPK6 and/or OsMAPK3 together with OsMKK4-dd increased PAL1 and OsWRKY19 expression in rice protoplasts
- OsMKK4, 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, 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
- OsMKK4, OsMPK1~OsMAPK6~OsSIPK, Involvement of the OsMKK4-OsMPK1 Cascade and its Downstream Transcription Factor OsWRKY53 in the Wounding Response in Rice, Further analysis revealed that OsMKK4, the upstream kinase of OsMPK1, phosphorylated OsMPK1 by wounding in vivo.
- OsMKK4, OsMPK1~OsMAPK6~OsSIPK, OsMAPK6, a mitogen-activated protein kinase, influences rice grain size and biomass production, As a functional kinase, OsMAPK6 interacts strongly with OsMKK4, indicating that OsMKK4 is likely to be the upstream MAPKK of OsMAPK6 in rice.
