6. Communication.
6.1. Chemical communication.
6.2. Pheromone triggered transitions of nonlinear systems.
6.3. Electrical communication
7. Bacillus subtilis competence and sporulation : the final exam.
7.1. Competence decision by noisy autofeedback.
7.2. Phosphorelay sensor for sporulation.
7.3. A mutually repressing circuit inhibits competence.
7.4. Input from intercellular communication.
Physical biology is a fusion of biology and physics. This book narrows down the scope of physical biology by focusing on the microbial cell; exploring the physical phenomena of noise, feedback, and variability that arise in the cellular information-processing circuits used by bacteria. It looks at the microbe from a physics perspective, asking how the cell optimizes its function to live within the constraints of physics. It introduces a physical and information-based (as opposed to microbiological) perspective on communication and signalling between microbes.
