Query: NC_008260:1015447 Alcanivorax borkumensis SK2, complete genome
Lineage: Alcanivorax borkumensis; Alcanivorax; Alcanivoracaceae; Oceanospirillales; Proteobacteria; Bacteria
General Information: This bacterium was isolated from a seawater sediment sample in the North Sea. The species is able to use Mihagol-S (C14,15-n-alkanes) as a principal carbon source. Using n-alkanes as a sole carbon source causes the strains to produce extracellular and membrane-bound surface-active glucose lipids. Phenotypic analysis showed a restricted nutritional profile, high halotolerance, the absence of fermentative metabolism, and a low G+C content. This, in combination with a 16S phylogenetic study, allowed the placing of this organism into a new genus.
Subject: NC_007705:755948 Xanthomonas oryzae pv. oryzae MAFF 311018, complete genome
Lineage: Xanthomonas oryzae; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: 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 pathogen 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. Causes disease in rice. 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 oryzicola causes bacterial streak. This disease is common in tropical area and can cause crop losses of up to 32%. 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.
