AbstractPlant phospholipase Ds (PLDs), essential regulators of phospholipid signaling, function in multiple signal transduction cascades; however, the mechanisms regulating PLDs in response to pathogens remain unclear. Here, we found that Arabidopsis (Arabidopsis thaliana) PLD delta accumulated in cells at the entry sites of the barley powdery mildew fungus, Blumeria graminis f. sp hordei. Using fluorescence recovery after photobleaching and single-molecule analysis, we observed higher PLD delta density in the plasma membrane after chitin treatment; PLD delta also underwent rapid exocytosis. Fluorescence resonance energy transfer with fluorescence lifetime imaging microscopy showed that the interaction between PLD delta and the microdomain marker AtREMORIN1.3 (AtREM1.3) increased in response to chitin, indicating that exocytosis facilitates rapid, efficient sorting of PLD delta into microdomains upon pathogen stimulus. We further unveiled a trade-off between brefeldin A (BFA)-resistant and -sensitive pathways in secretion of PLD delta under diverse conditions. Upon pathogen attack, PLD delta secretion involved syntaxin-associated VAMP721/722-mediated exocytosis sensitive to BFA. Analysis of phosphatidic acid (PA), hydrogen peroxide, and jasmonic acid (JA) levels and expression of related genes indicated that the relocalization of PLD delta is crucial for its activation to produce PA and initiate reactive oxygen species and JA signaling pathways. Together, our findings revealed that the translocation of PLD delta to papillae is modulated by exocytosis, thus triggering PA-mediated signaling in plant innate immunity.
