Conserved role of the SERK and BIR module in development and immunity across land plants. Marchantia polymorpha

SERK as a co-receptor, plays diverse roles in both immunity and development in angiosperm. BIRs interact with SERKs under resting conditions, negatively regulating SERK-mediated pathways. In Marchantia polymorpha, SERK-BIR module is evolutionary conserved and MpBIR interacts with MpSERK. However, the functional relationship between MpSERK and MpBIR is unknown. To investigate the function of SERK-BIR module in M. polymorpha, we performed the transcriptome analysis of Mpbir-1, Mpbir-3, Mpserk-3, and wild-type Tak-1
