Taxonomy:	Bacteria; Proteobacteria; Alphaproteobacteria; Caulobacterales; Caulobacteraceae; Caulobacter (TaxID: 366602) [NEWT/ NCBI]
Description:	Caulobacter sp. (strain K31) was isolated from a low-oxygen groundwater sample and is being sequenced for comparative genome analysis.This organism inhabits aquatic environments and plays an important part in biogeochemical cycling of organic nutrients. It 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.
