Sensory Control and Function of Bacterial Bioluminescence.

Abstract

The goal of this project was to explore the sensory mechanisms which control expression of bioluminescence in the marine bacterium Vibrio harveyi. Genetic methods were used to discover a complex network of genes which encode functions for the production of extracellular, chemical signals (autoinducers) and for the synthesis of signal receptors (sensor kinases and response regulators). The genes and proteins defined by this study resemble elements of the phosphorelay paradigm known as two-component signal transduction. Therefore, the Vibrio harveyi system is considerably different from the quorum sensing mechanism used by other luminous bacteria.
