Two-Component Sensor Required for Normal Symbiotic Colonization of Euprymna scolopes by Vibrio fischeri

Karen L. Visick, Line M. Skoufos, Journal of Bacteriology

This Journal of Bacteriology scholarly article explores factors contributing to the specificity of the Euprymna scolopes Vibrio fischeri symbiosis. By studying random transposon mutants defective in initiating the symbiotic association or in colonizing the light organ to high density, locus rscS (a regulator of symbiotic colonization sensor) was identified. Results of this study led to the hypothesis that RscS recognizes a signal associated with the light organ environment and responds by stimulating a putative response regulator that controls protein function or gene expression in order to coordinate early colonization events.
