Abstract
The bacterial cytoskeleton is crucial for sensing the external environment and plays a major role in cell to cell communication. There are several other apparatuses such as conjugation tubes, membrane vesicles, and nanotubes used by bacterial cells for communication. The present review article describes the various bacterial cytoskeletal proteins and other apparatuses, the physical structures they form and their role in sensing environmental stress. The implications of this cellular communication in pathogenicity are discussed.
Highlights
In order to survive in the changing environmental conditions, microorganisms have evolved two broadly described complex communication systems- the contact-independent quorum sensing (QS) and the contact-dependent signaling mechanisms (Bassler and Losick, 2006; Blango and Mulvey, 2009)
Cellular communications are usually mediated through synthesis, secretion and detection of signaling molecules commonly known as the inducers, which are released in the environment directly or through various cellular apparatuses (Kaprelyants and Kell, 1996)
The present review describes the role of bacterial cytoskeleton and contact dependent signaling through cellular apparatuses which play a major role in cellular communication
