Proposed model of PIBP4-Rab5a-mediated PigmR plasma membrane microdomain anchoring and blast resistance in rice

Caption

Upon perception of blast pathogen effectors by the NLR, PIBP4 and OsRab5a-mediated trafficking vesicles likely promote the localization of part of PigmR to microdomains where PigmR interacts with and activates OsRac1, which triggers ROS signaling and leads to disease resistance.
