Outer Membrane Vesicles as Mediators of Plant–Bacterial Interactions
Plants have co-evolved with diverse microorganisms that have developed different
mechanisms of direct and indirect interactions with their host. Recently, greater attention
has been paid to a direct “message” delivery pathway from bacteria to plants, mediated
by the outer membrane vesicles (OMVs). OMVs produced by Gram-negative bacteria
play significant roles in multiple interactions with other bacteria within the same
community, the environment, and colonized hosts. The combined forces of innovative
technologies and experience in the area of plant–bacterial interactions have put pressure
on a detailed examination of the OMVs composition, the routes of their delivery
to plant cells, and their significance in pathogenesis, protection, and plant growth
promotion. This review synthesizes the available knowledge on OMVs in the context
of possible mechanisms of interactions between OMVs, bacteria, and plant cells. OMVs
are considered to be potential stimulators of the plant immune system, holding potential
for application in plant bioprotection
