(Submitter supplied) The marine bacterium Vibrio fischeri requires flagellar motility to undergo symbiotic initiation with its host, the Hawaiian bobtail squid Euprymna scolopes. We sought to identify the genes activated by the sigma54-dependent flagellar master regulator, FlrA, in V. fischeri, thereby determining the flagellar regulon in this model symbiont.

(Submitter supplied) The bioluminescent bacterium Vibrio fischeri initiates a specific, persistent symbiosis in the light organ of the squid Euprymna scolopes. During the early stages of colonization, V. fischeri is exposed to host-derived nitric oxide (NO). While NO can be both an antimicrobial component of innate immunity and a common signaling molecule of eukaryotes, its roles in beneficial host-microbe associations remain undescribed. more...

(Submitter supplied) Acyl-homoserine lactone (acyl-HSL) quorum sensing was first discovered in Vibrio fischeri where it serves as a key control element of the seven-gene luminescence (lux) operon. Since this initial discovery, other bacteria have been shown to control hundreds of genes by acyl-HSL quorum sensing. Until recently, it has been difficult to examine the global nature of quorum sensing in V. fischeri. However, the complete genome sequence of V. more...
