Effect of transposon-induced motility mutations on colonization of the host light organ by Vibrio fischeri.
Vibrio fischeri is found both as a free-living bacterium in seawater and as the specific, mutualistic light organ symbiont of several fish and squid species. To identify those characteristics ofExpand

AinS and a new family of autoinducer synthesis proteins.
In Vibrio fischeri, the autoinducer N-3-oxohexanoyl-L-homoserine lactone (AI-1) governs the cell density-dependent induction of the luminescence operon via the LuxR transcriptional activator. TheExpand

Reclassification of Vibrio fischeri, Vibrio logei, Vibrio salmonicida and Vibrio wodanis as Aliivibrio fischeri gen. nov., comb. nov., Aliivibrio logei comb. nov., Aliivibrio salmonicida comb. nov.
Four closely related species, Vibrio fischeri, Vibrio logei, Vibrio salmonicida and Vibrio wodanis, form a clade within the family Vibrionaceae; the taxonomic status and phylogenetic position of thisExpand

Multiple N-acyl-L-homoserine lactone autoinducers of luminescence in the marine symbiotic bacterium Vibrio fischeri.
In Vibrio fischeri, the synthesis of N-3-oxohexanoyl-L-homoserine lactone, the autoinducer for population density-responsive induction of the luminescence operon (the lux operon, luxICDABEG), isExpand

Modulation of luminescence operon expression by N-octanoyl-L-homoserine lactone in ainS mutants of Vibrio fischeri.
Population density-dependent expression of luminescence in Vibrio fischeri is controlled by the autoinducer N-3-oxohexanoyl-L-homoserine lactone (autoinducer 1 [AI-1]), which via LuxR activatesExpand

Acylhomoserine lactone synthase activity of the Vibrio fischeri AinS protein.
Acylhomoserine lactones, which serve as quorum-sensing signals in gram-negative bacteria, are produced by members of the LuxI family of synthases. LuxI is a Vibrio fischeri enzyme that catalyzes theExpand

Phylogeny, genomics, and symbiosis of Photobacterium.
Photobacterium comprises several species in Vibrionaceae, a large family of Gram-negative, facultatively aerobic, bacteria that commonly associate with marine animals. Members of the genus are widelyExpand

Phylogenetic analysis of the incidence of lux gene horizontal transfer in Vibrionaceae.
Horizontal gene transfer (HGT) is thought to occur frequently in bacteria in nature and to play an important role in bacterial evolution, contributing to the formation of new species. To gain insightExpand
