Description and significance
Though this bacteria was studied starting from the early 1980's it was finally sequenced by the Kazusa DNA Research institute in 2000.
Mesorhizobium loti is a member of rhizobia (rhizobia is a collective name for the genera of Rhizobium, Sinorhizobium, Mesorhizobium, and Bradyrhizobium). They are soil and rhizosphere bacteria which perform nitrogen-fixing symbiosis with leguminous plants. Nitrogen fixation reulsts from a series of interactions controlled by the exchange of molecular signals between symbiotic bacteria and host plants followed by expression of genes from both symbiotic partners.
Specifically, the Mesorhizobium species has the ability to form nodules and was studied in order to further understand the process of symbiotic nitrogen fixation as well as horizontal gene transfer among natural microsymbionts.
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?
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?
