Query: NC_012721:109500 Burkholderia glumae BGR1 chromosome 2, 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.

General Information: Originally identified as Pseudomonas sp. LB400 that was found in contaminated soil in upstate New York, USA, this organism is now classified in the genus Burkholderia. Polychlorinated biphenyl-degrading bacterium. Member of the genus Burkholderia are versatile organisms that occupy a surprisingly wide range of ecological niches. These bacteria are exploited for biocontrol, bioremediation, and plant growth promotion purposes. Burkholderia xenovorans has been found on fungi, animals, and from human clinical isolates such as from cystic fibrosis (CF) patients. It may be tightly associated with white-rot fungus, as the degadation of lignin by the fungus results in aromatic compounds the bacterium can then degrade. This organism is exceptionally capable of degradation of polychlorinated biphenyls (PCBs), which are environmental pollutants, and thus it may play a role in bioremediation of polluted and toxic sites and is studied as a model bioremediator. PCBs can be utilized as the sole carbon and energy source by this organism. The pathways for degradation of PCBs have been extensively characterized at both the genetic and the molecular level and have become a model system for the bacterial breakdown of these very persistent environmental contaminants.
