Susceptibility genes involved in basic compatibility and sustained compatibility during the host-pathogen interactions. a, b Examples of the S genes involved in the early infection process. OSK1, OsABA1/OsABA2/OsABA3, and OsSCAR2 negatively regulate stomatal immunity, stomatal conductance, and stomatal density, respectively. OsPG1, OsRBL1, and OsRacB/OsRac5/OsRac4 are involved in cell wall degradation, effector secretion, and formation of the extrahaustorial membrane, respectively. PA, phosphatidic acid; CDP-DAG, cytidine diphosphate diacylglycerol; PI, phosphatidylinositol; BIC, biotrophic interfacial complex; EIHM, extra-invasive hyphal membrane. c Examples of the S genes involved in compatible interaction during post-penetration stages of infection. OsPIP1;3 facilitates the secretion of the effector PthoXo1 into the host cytosol. OsImpα1a and OsImpα1b contribute to the translocation of bacterial TALEs into rice nuclei. The promoters of S genes, OsSWEET11, OsSWEET13, OsSWEET14, OsTFX1, OsERF123, and OsTFIIγ1, are targeted by various effectors. Arrows indicate positive regulation; the blunt-ended line indicates negative regulation. Created with BioRender (www. BioRender.com)
