Genome analysis of Erwinia carotovora indicates that this organism not only fixes nitrogen but also catabolize plant-produced opines. Along with all six of the known secretion systems, the chromosome also encodes a sizeable collection of plant cell wall-degrading enzymes such as pectinases. This signifies the bactium's ability produce pathogenicity determinants such as the aforementioned degradative enzymes and avirulence proteins. Disruption of the type IV secretion system affected virulence, which suggests this does not simply reflect an integrated plasmid in the chromosome. | |||

Genus species
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.
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?
Genome analysis of Erwinia carotovora indicates that this organism not only fixes nitrogen but also catabolize plant-produced opines. Along with all six of the known secretion systems, the chromosome also encodes a sizeable collection of plant cell wall-degrading enzymes such as pectinases. This signifies the bactium's ability produce pathogenicity determinants such as the aforementioned degradative enzymes and avirulence proteins. Disruption of the type IV secretion system affected virulence, which suggests this does not simply reflect an integrated plasmid in the chromosome.
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
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?
