| It is known that, in bacteria, genes are expressed as a response to metabolic or any external stress in order to increase their chance of survival. One such gene in E.coli is the rpoS gene; it regulates the expression of a wide variety of stress-related genes which triggers entrance into stationary phase. We use a genetically engineered rpoS mutant to study the interaction of two competing species of bacteria. |  Microfabricated environments are used to study the evolutionary dynamics of bacteria when subjected to metabolic or physical stress |
