Query: NC_005773:1135374 Pseudomonas syringae pv. phaseolicola 1448A, complete genome
Lineage: Pseudomonas savastanoi; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: This is gram-negative bacterium pathogenic in plants. Characterized as causing halo blight on beans (Phaseolus vulgaris). This bacterium is closely related to Pseudomonas syringae pv. glycinea and Pseudomonas syringae pv. savastanoi and produces phaseolotoxin, which is a phytotoxin. Strain 1448A is a natural occurring rifampicin-resistant mutant strain and contains a non-functional homolog of avrPphE.
Subject: NC_003063:304962 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.
