SmcR-dependent regulation of adaptive phenotypes in Vibrio vulnificus

Vibrio vulnificus contains homologues of the V. harveyi luxR and luxS genes. A null mutation In smcR (luxR) resulted in a defect in starvation survival, inhibition of starvation-induced maintenance of culturability that occurs when V. vulnificus is starved prior to low-temperature incubation, and increased expression of stationary-phase phenotypes.
