Abstract excerpt
BACKGROUND: Quorum sensing (QS) is a form of gene regulation based on cell-density that depends on inter-cellular communication. While there are a variety of models for bacterial colony morphology, there is little work linking QS genes to movement in an open system. RESULTS: The onset of swarming in environmental P. aeruginosa PUPa3 was described with a simplified computational model in which cells in random...
