Query: NC_004545:499709 Buchnera aphidicola str. Bp (Baizongia pistaciae), complete genome

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

General Information: This organism is found in the aphid Baizongia pistaciae. Aphid endosymbiont. 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_014538:73272 Thermoanaerobacter sp. X513 chromosome, complete genome

Lineage: Thermoanaerobacter; Thermoanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria

General Information: Country: USA; Environment: Fresh water; Isolation: Deep subsurface location at the Piceance Basin, Colorado, USA; Temp: Thermophile; Temp: 60C. Thermoanaerobacter sp. (strain X513) is an anaerobic, extreme thermophilic Gram-positive bacterium isolated by anaerobic enrichment culture from a deep subsurface sample (2000 m below the surface) taken from a core hole at the Piceance Basin, Colorado, USA. It can use a variety of electron donors, including glucose, acetate, hydrogen and xylose while reducing iron, chromium and uranium at 60 degrees.
