Query: NC_010717:4851000 Xanthomonas oryzae pv. oryzae PXO99A, complete genome Lineage: Xanthomonas oryzae; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria General Information: This strain is a representative strain of race 6 isolated in the Philippines. This plant pathogen affects rice plants by causing leaf blight, a major problem in Asian countries where rice production occurs on an industrial scale. This organism enters the xylem and spreads throughout the vascular tissue of the plant, which results in wilting of the plant, or to leaf blight if the infection occurs later in development. This genus consists of plant-specific yellow-pigmented microbes, some of which are economically important phytopathogens that devastate crops such as citrus plants, rice, beans, grape, and cotton. These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. Xanthomonas oryzae contains two pathovars which cause enconomically significant diseases in rice. Xanthomonas oryzae pathovar oryzae causes bacterial leaf blight which is one of the most serious diseases of rice. This disease is common in temperate and tropical areas and can cause significant crop loss.

General Information: This strain is a derivative strain isolated in the laboratory of Barry Marrs from the classical progenitor strain B10. It is rifampicin-resistant, produces GTA, and is capable of growing under high illumination (resistant to photooxidative killing). Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to use photosynthesis and usually can grow under both anaerobic and aerobic conditions. This organism is a facultatively phototrophic purple non-sulfur bacterium and the type species of the Rhodobacter group. The colony's color depends largely on the amount of oxygen present in its environment. While it is able to produce cellular energy in a number of different ways, it can rely on anoxygenic photosynthesis under anaerobic conditions in the presence of light. Some strains produce the Gene Transfer Element (GTA), a pro-phage particle capable of transferring genetic material between strains.
