Query: NC_015596:1556007 Sinorhizobium meliloti AK83 chromosome 2, complete sequence
Lineage: Sinorhizobium meliloti; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Environment: Host, Plant root, Root nodule, Soil; Temp: Mesophile; Temp: 25 - 30C. This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, in this case the alfalfa plant (Medicago sativa). Expression of nodulation genes results in production of a nodulation signal which the plant cell recognizes inducing root nodule formation. The plant cell provides carbon compounds for the bacterium to grow on.
Subject: NC_014816:545441 Asticcacaulis excentricus CB 48 chromosome 1, complete sequence
Lineage: Asticcacaulis excentricus; Asticcacaulis; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Environment: Fresh water; Isolation: Pondwater; Temp: Mesophile; Isolation: pond water. Asticcacaulis excentricus 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. Thus, the asymmetric processes in this organism provide useful models for differentiation and development.
