Query: NC_008027:1559083 Pseudomonas entomophila L48, complete genome Lineage: Pseudomonas entomophila; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria General Information: Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. This organism is highly pathogenic for a variety of insects in both larvae and adults. It was isolated from fruit flies and decaying fruits taken from a sample set obtained from the Island of Guadeloupe and tested for induction of a systemic immune response in Drosophila. Destruction of the insect gut tissue occurs during infection.Analysis of the proteins encoded by the genome indicated a number of potential virulence factors, although a type III secretion system was not found.

General Information: Marinomonas MWYL1 was isolated from the root surface of the salt marsh grass Spartina anglica, growing near the North Norfolk, England village of Stiffkey. The genus Marinomonas comprises a widespread group of g -proteobacteria that exist in coastal waters, and which had been earlier been included in the genus Alteromonas. The interest in Marinomonas MWYL 1 was that it could grow on the betaine molecule Dimethylsulphoniopropionate (DMSP) as sole carbon source and, when it did do, it released large amounts of the gas dimethyl sulphide. DMSP is a compatible solute that is used by many marine phytoplankton and seaweed macroalgae as an osmoticum and an anti-stress compound. In addition, a few known land angiosperms make DMSP and these include certain species of Spartina - hence the choice of these plants as a source for DMSP-degrading bacteria. Indeed, others had shown previously that the DMSP-catabolising bacteria isolated from Spartina root surfaces included Marinomonas strains.
