Query: NS_000191:120700 Uncultured Termite group 1 bacterium phylotype Rs-D17, complete
Lineage: uncultured Termite group 1 bacterium; enviromental sample; ; ; Elusimicrobia; Bacteria
General Information: Termite gut symbion. Termites harbor a symbiotic gut microbial community that is responsible for their ability to thrive on recalcitrant plant matter. Found specifically within the cells of the cellulolytic flagellate Trichonympha agilis in the gut of the termite Reticulitermes speratus.
Subject: NC_016047:261304 Bacillus subtilis subsp. spizizenii TU-B-10 chromosome, complete
Lineage: Bacillus subtilis; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: This organism was one of the first bacteria studied, and was named Vibrio subtilis in 1835 and renamed Bacillus subtilis in 1872. It is one of the most well characterized bacterial organisms, and is a model system for cell differentiation and development. This soil bacterium can divide asymmetrically, producing an endospore that is resistant to environmental factors such as heat, acid, and salt, and which can persist in the environment for long periods of time. The endospore is formed at times of nutritional stress, allowing the organism to persist in the environment until conditions become favorable. Prior to the decision to produce the spore the bacterium might become motile, through the production of flagella, and also take up DNA from the environment through the competence system. The sporulation process is complex and involves the coordinated regulation of hundreds of genes in the genome. This initial step results in the coordinated asymmetric cellular division and endospore formation through multiple stages that produces a single spore from the mother cell.
