Query: NC_000868:196015 Pyrococcus abyssi GE5, complete genome
Lineage: Pyrococcus abyssi; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This organism was isolated from an active chimney in the North Fiji Basin of the Pacific Ocean at a depth of 3500 meters. This organism is an obligate anaerobic, hyperthermophilic archaeon. Growth occurs at a temperature of 67-103 degrees C with optimal growth at 103 degrees C at 200 atmospheres of pressure. Increased hydrostatic pressure has been found to extend the upper growth temperature and stimulate growth.
Subject: NC_003063:757999 Agrobacterium tumefaciens str. C58 chromosome linear, complete
Lineage: Agrobacterium fabrum; Agrobacterium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain is a biovar 1 nopaline-producing strain originally isolated from a cherry tree tumor. Strains of Agrobacterium are classified in three biovars based on their utilisation of different carbohydrates and other biochemical tests. The differences between biovars are determined by genes on the single circle of chromosomal DNA. Biovar differences are not particularly relevant to the pathogenicity of A. tumefaciens, except in one respect: biovar 3 is found worldwide as the pathogen of gravevines. This species causes crown gall disease of a wide range of dicotyledonous (broad-leaved) plants, especially members of the rose family such as apple, pear, peach, cherry, almond, raspberry and roses. Because of the way that it infects other organisms, this bacterium has been used as a tool in plant breeding. Any desired genes, such as insecticidal toxin genes or herbicide-resistance genes, can be engineered into the bacterial DNA, and then inserted into the plant genome. This process shortens the conventional plant breeding process, and allows entirely new (non-plant) genes to be engineered into crops.
