Query: NC_009511:187508 Sphingomonas wittichii RW1 chromosome, complete genome
Lineage: Sphingomonas wittichii; Sphingomonas; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Sphingomonas wittichii was isolated from water from the Elbe River in Germany. This organism is able to grow using dibenzo-p-dioxin or dibenzofuran as a sole carbon source. These compounds are widespread environmental contaminants formed as by-products in the manufacture of pesticides and paper, and during the incineration of industrial waste. The enzymes involved in degradation of these substrates is contained, in part, on plasmids in Sphingomonas wittichii.
Subject: NC_004129:195347 Pseudomonas fluorescens Pf-5, complete genome
Lineage: Pseudomonas protegens Pf-5; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: This strain can suppress the diseases caused by Rhizoctonia solani and Pythium ultimum which affect cotton plants. The production of a number of antibiotics (pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol) as well as the production of siderophores (which may affect the ability of competing organisms to obtain environmental iron) by this strain can inhibit phytopathogen growth such as the above-mentioned fungi. The genome of this organism contains a number of genes, estimated at 5.7 % of the chromosome, that encode proteins that are involved in secondary metabolism. A large number of repeat elements (REP) are also found in the genome in greater numbers than in related Pseudomonas spp.
