Query: NC_012724:1914740 Burkholderia glumae BGR1 chromosome 1, complete genome
Lineage: Burkholderia glumae; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Burkholderia glumae causes seedling rot and panicle blight of rice. Panicle blight is a significant problem in the southern USA during unusually warm growing seasons. Infection of rice with Burkholderia glumae causes sterility, or abortion, of the rice kernels, and may inhibit seed germination. Burkholderia glumae also produces an industrially important extracellular lipase.
Subject: NC_003305:1 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.
