A PRA-Rab trafficking machinery modulates NLR immune receptor plasma membrane microdomain anchoring and blast resistance in rice
This study identified PIBP4, a PRA protein, as a crucial component of the PigmR-mediated immune signaling pathway in rice. The absence of PIBP4 and its interacting partner OsRab5a compromised blast resistance by disrupting PigmR's microdomain localization.
