Query: NC_004061:166375 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.

Subject: NC_014259:3369000 Acinetobacter sp. DR1 chromosome, complete genome

Lineage: Acinetobacter oleivorans; Acinetobacter; Moraxellaceae; Pseudomonadales; Proteobacteria; Bacteria

General Information: This strain is capable of degrading paraffin, n-hexadecane, diesel. Acinetobacter sp. DR1 is a diesel degrader Gram-negative bacterium isolated from the soil of rice paddies in Soth Korea. They are found in many different habitats, including soil, water, and sewage, as well as in a variety of foodstuffs. They are also members of the normal microflora of human skin, and have been implicated as a presumed causative or contributory agent of numerous nosocomial (in-hospital) infections, especially those in immunocompromised individuals. Due to their genomic versatility, these bacteria are highly adaptive to treatment with various antibiotic reagents.
