Query: NC_007086:459934 Xanthomonas campestris pv. campestris str. 8004, complete genome
Lineage: Xanthomonas campestris; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: The original was isolated from an inflected cauliflower in Sussex, United Kingdom, in 1958. Strain 8004 is a spontaneous rifampicin resistant strain. Causes black rot disease in crucifers. These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. This species is a major cause of black rot in crucifers, a disease that results in massive tissue degeneration. It also produces an extracellular polysaccharide known as xanthan, which is harvested commercially as a food stabilizing agent for use in industry.
Subject: NC_015711:570910 Myxococcus fulvus HW-1 chromosome, complete genome
Lineage: Myxococcus fulvus; Myxococcus; Myxococcaceae; Myxococcales; Proteobacteria; Bacteria
General Information: This organism, like other myxobacteria, undergoes a complex development and differentiation pathway. When cell density increases, the organism switches to "social motility" where aggregates of cells can gather together into masses termed fruiting bodies that may consist of up to 100 000 cells. The motility system is not dependent on flagella like most bacteria, but instead relies on twitching pili: short extracellular appendages that may function analogously to oars in a rowboat. The myxobacteria have proved to be a rich source of novel natural products. Myxococcus fulvus produces a number of antibacterial, antifungal and cytotoxic substances which are being studies for therapeutic applications.
