Query: NC_009937:5033152 Azorhizobium caulinodans ORS 571, complete genome
Lineage: Azorhizobium caulinodans; Azorhizobium; Xanthobacteraceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This species is a stem-nodulating nitrogen-fixing organism isolated from Sesbania rostrata. Azorhizobium caulinodans ORS571 is a microsymbiont of the water-tolerant tropical legume Sesbania rostrata.A. caulinodans ORS571 is able to fix nitrogen in the free-living state, which is not the case for most rhizobia.
Subject: NC_003305:1297785 Agrobacterium tumefaciens str. C58 chromosome linear, complete
Lineage: Agrobacterium tumefaciens; Agrobacterium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Gram-negative soil bacterium. This is the most widely studied species in the genus. 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.
