Caulobacter crescentus, also known as Caulobacter vibroides, inhabits aquatic environments and plays an important part in biogeochemical cycling of organic nutrients. This bacterium undergoes an unusual developmental cycle in which a swarming motile cell becomes a stalked cell that is attached to a solid surface. The stalked cell then undergoes asymmetric cell division and produces one flagellated motile daughter cell and one stalked daughter cell. The stalked cell immediately undergoes replication and division, while in the swarmer cell these processes are inhibited. Thus, the asymmetric processes in this organism provide useful models for differentiation and development. Differentiation is managed through a control circuit that is comprised of various switches that regulate, through temporal expression, phosphorylation, and targeted proteolysis, the developmental process. This organism also contains a number of energy-dependent transport system, presumably enabling growth in the substrate-sparse aquatic environments that it lives in. Caulobacter crescentus (strain NA1000) is a spontaneous mutant derivative of C. crescentus strain CB15. It is used by labs worldwide because it can easily be synchronized, allowing for studies of the bacterial cell cycle. (adaptated from
