Arabidopsis Produces Distinct Subpopulations of Extracellular Vesicles That Respond Differentially to Biotic Stress, Altering Growth and Infectivity of a Fungal Pathogen

Abstract excerpt

Extracellular vesicles (EVs) secreted by mammalian cells are highly heterogeneous in content and function. Whether this is also true for EVs secreted by plant cells is not yet known. To address this, we used high-resolution density gradient ultracentrifugation and total internal fluorescence microscopy (TIRF-M) to purify and distinguish distinct subpopulations of Arabidopsis EVs. The EV marker protein TETRASPANIN...
