Effect of transposon-induced motility mutations on colonization of the host light organ by Vibrio fischeri
TLDR
Motility is identified as the first required symbiotic phenotype of V. fischeri, indicating that the presence of flagella alone is not sufficient for colonization and that it is motility itself that is required for successful light organ colonization. Expand
AinS and a new family of autoinducer synthesis proteins
TLDR
The existence of two different and unrelated autoinducer synthesis genes suggests the occurrence of convergent evolution in the synthesis of homoserine lactone signaling molecules. Expand
Multiple N-acyl-L-homoserine lactone autoinducers of luminescence in the marine symbiotic bacterium Vibrio fischeri
TLDR
The presence of multiple chemically and genetically distinct but cross-acting autoinduction systems in V. fischeri indicates unexpected complexity forAutoinduction as a regulatory mechanism in this bacterium. Expand
Modulation of luminescence operon expression by N-octanoyl-L-homoserine lactone in ainS mutants of Vibrio fischeri
TLDR
It is concluded that AI-2 inhibits lux operon transcription, and apparently functions in V. fischeri to suppress or delay induction at low and intermediate population densities. Expand
Acylhomoserine Lactone Synthase Activity of the Vibrio fischeri AinS Protein
TLDR
It is concluded that AinS is an acylhomoserine lactone synthase and that it represents a second family of such enzymes. Expand
Regulation of luminescence by cyclic AMP in cya-like and crp-like mutants of Vibrio fischeri

  • 1 February 1989
TLDR
Mutants of Vibrio fischeri MJ-1 apparently deficient in adenylate cyclase (cya-like) or cyclic AMP receptor protein (crp- like) were isolated and characterized and addition of cyclicAMP restored wild-type levels of luminescence and luciferase in the cya- like mutant but not in the crp-like mutant.

Phylogenetic Analysis of the Incidence of lux Gene Horizontal Transfer in Vibrionaceae
TLDR
The results indicate that horizontal transfer of the lux genes in nature is rare and that horizontal acquisition of thelux genes apparently has not contributed to speciation in recipient taxa. Expand
Phylogeny, genomics, and symbiosis of Photobacterium.
TLDR
Phylogenetic analysis demonstrates a robust separation between Photobacterium and its close relatives, Aliivibrio and Vibrio, and reveals the presence of two well-supported clades. Expand
Quorum regulation of luminescence in Vibrio fischeri.

  • 1 August 1999
TLDR
Quorum regulation in V. fischeri serves as a model for LuxI/LuxR-type quorum sensing systems in other gram-negative bacteria. Expand
Laboratory Culture of the Sepiolid Squid Euprymna scolopes: A Model System for Bacteria-Animal Symbiosis.
TLDR
The small Hawaiian sepiolid Euprymna scolopes, with its symbiotic luminous bacterium Vibrio fischeri, was cultured through one complete life cycle in 4 months, indicating that the host organism of this symbiosis can soon be cultured with consistency through its brief life cycle, thus opening new avenues of research into developmental aspects ofThis symbiosis.
