Species
Bacillus thuringiensis
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? Bacillus thuringiensis has a circular plasmid chromosome. Due to its 2% GC-content, it has more A/G base pairs. Compared to its bacterial relatives, Bt's genome is not big at all. It is only 5,475 nucleotides long and consists of only seven genes: pK1S1_p1, pK1S1_p2, pK1S1_p3, pK1S1_p4, pK1S1_p5, pK1S1_p6, and pK1S1_p7.
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?
