Outline
Bacterial membrane vesicles (MVs), which are a kind of biological nanoparticles carrying proteins, nucleic acids, signaling molecules, and other important compounds, are involved in a variety of physiological and biochemical processes, such as horizontal gene transfer, quorum sensing, biofilm formation and so on. Studies showed that marine extracellular vesicles might be the third largest biological entity except for phages and bacteria. Besides, MVs-mediated intercellular communication across species could be of great significance to marine ecosystems. However, very little is known about the specific ecological role and biological function of MVs in the marine biosphere. In this review, we discuss the role of bacterial MVs in marine micro-ecology, marine symbiotic system, and the impact of MVs-mediated material delivery on marine ecosystem. Meanwhile, we also put forward some questions and opinions for study in marine bacterial MVs’ research.
