Lineage: Alkalilimnicola ehrlichii; Alkalilimnicola; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria

General Information: This chemoautotrophic strain was isolated from Mono Lake in California, which contains arsenic and has high pH and salt concentrations. Arsenite-oxidizing bacterium. Alkalilimnicola ehrlichei is capable of growth with arsenite [As(III)] as the electron donor with nitrate as electron acceptor. It may be responsible for production of arsenate [As(V)] in anoxic lake bottom.

Subject: NC_004061:540354 Buchnera aphidicola str. Sg (Schizaphis graminum), complete genome

Lineage: Buchnera aphidicola; Buchnera; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This strain is the symbiont of the aphid Schizaphis graminum and contains a large circular chromosome. Aphid endosymbiont. Almost all aphids contain maternally transmitted bacteriocyte cells, which themselves contain bacteria called Buchnera. The aphids live on a restricted diet (plant sap), rich in carbohydrates, but poor in nitrogenous or other essential compounds. It is believed that the Buchnera provide the essential nutrients the host lacks. Besides a nutritional co-dependence, due to a co-existence of millions of years, Buchnera have lost the ability to produce cell surface components such as lipopolysaccharides. This makes for an obligate endosymbiont relationship between host and Buchnera. Buchnera are prokaryotic cells which belong to the gamma-Proteobacteria, closely related to the Enterobacteriaceae family. Phylogenetic studies using 16S rRNA indicate that the symbiotic relationship was established around 200-250 million years ago. Since Buchnera are closely related to Escherichia coli and Haemophilus influenzae, comparative genomic studies can shed light on the evolutionary mechanisms of intracellular endosymbiosis as well as the different underlying molecular basis between organisms with parasitic behavior and symbionts.
