Timeline of plant-derived extracellular vesicles research. The first observation of PDEVs came from electronic transmission microscopy in the 1960s. For several years they were correlated to the response against pathogens, until it their capability to mediate the cross-kingdom communication was demonstrated. MVBs, multivesicular bodies; PDEVs, plant-derived extracellular vesicles.
