Abstract: Outer membrane vesicles (OMVs) are released from Pseudomonas syringae pv. tomato T1 (Pst T1) during their normal growth. These extracellular compartments are comprised of a complete set of biological macromolecules that includes proteins, lipids, lipopolysaccharides, etc. It is evident from proteomics analyses the OMVs of Pst T1 contain membrane- and virulence-associated proteins. In addition, OMVs of this organism are also associated with phytotoxin, coronatine. Therefore, OMVs of Pst T1 must play a significant role during pathogenicity to host plant. However, further studies are required whether these structures can serve as "vehicles" for the transport of virulence factors into the host membrane.<br /> (Copyright © 2012 Elsevier B.V.
