My project focus is the identification and functional characterization of Outer membrane vesicles (OMVs) of Pectobacterium brasiliense 1692. OMV production is a critical and evolutionarily conserved process in Gram-negative bacteria (GNB) for survival in favorable and stressful environments. Our interest in the OMVs is due to their unique ability to secrete proteins of all the six secretion systems known to GNB providing the systems with relief from the arduous task of protein secretion. We seek to have a comprehensive picture of the role of OMVs of the aggressive soft rot bacteria Pb1692.
