LitR and its quorum-sensing regulators modulate biofilm formation by Vibrio fischeri.

ABSTRACT: Quorum sensing controls numerous processes ranging from the production of virulence factors to biofilm formation. Biofilms, communities of bacteria that are attached to one another and/or a surface, are common in nature, and when they form, they can produce a quorum of bacteria. One model system to study biofilms is the bacterium Vibrio fischeri, which forms a biofilm that promotes the colonization of its symbiotic host. Many factors promote V. fischeri biofilm formation in vitro, including the symbiosis polysaccharide (SYP) and cellulose, but the role of quorum sensing is currently understudied. Recently, a quorum-sensing-dependent transcription factor, LitR, was shown to negatively influence V. fischeri biofilm formation in the context of a biofilm-overproduci
