Query: NC_017271:770000 Xanthomonas campestris pv. raphani 756C chromosome, complete
Lineage: Xanthomonas campestris; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: 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_007651:1662558 Burkholderia thailandensis E264 chromosome I, complete sequence
Lineage: Burkholderia thailandensis; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This organism was originally isolated from a rice field sample in Thailand. Burkholderia thailandensis is a common soil saprophyte (lives on decaying organic matter in the soil). This bacterium is very similar to the human and animal pathogen Burkholderia pseudomallei but appears to be avirulent. Distinguishing the two organisms is very difficult and may depend on using monoclonal antibodies to detect differences in exopolysaccharide production.
