In this study, we demonstrated that the putative Vibrio fischeri rpoN gene, which encodes {sigma}54, controls flagellar biogenesis, biofilm development, and bioluminescence. We also show that rpoN plays a requisite role initiating the symbiotic association of V. fischeri with juveniles of the squid Euprymna scolopes.
