Popis: | The extracellular vesicles (EVs) released by plant pathogens of the Pectobacterium genus were investigated. The isolates were obtained using differential centrifugation followed by filtration and were characterized in terms of total protein content and particle size distribution. The transmission electron microscopy (TEM) analysis revealed the presence of two morphologically differentiated subpopulations of vesicles in the obtained isolates. The proteomic analysis using matrix-assisted laser desorption ionization mass spectrometry with time of flight detector (MALDI-TOF/TOF-MS) enabled to identify 62 proteomic markers commonly found in EVs of Gram-negative rods from the Enterobacteriaceae family. Capillary electrophoresis (CE) was proposed as a novel tool for the characterization of EVs. The method allowed for automated and fast ( |
