Description and significance
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.
P. fluorescens are gram-negative rod shaped bacteria. They possess multiple polar flagella for motility. The main habitats include soil, plants, and water. Soluble, green fluorescent pigments are produced when iron concentration is low. The significance of these organisms have increased because of their ability to degrade various pollutants and their use as biocontrol against pathogens.
Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
Currently, two strains of P. fluorescens have the genomes sequenced completely. has one chromosome
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
produces viscosin which is a peptidolipid that enhances antivirality. P. fluorescensuses a sulfate transport system that is competitively inhibited by chromate, which may be associated to P. flurorescens's sensitivity to chromate.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
P. fluorescens produce exopolysaccharides which are used for protection against bacteriophages or dehydration as well as for defense against the host immune system. Polysaccharides are being used within the food, chemical, and agricultural industries.
