Rhizobium Etli

Description and significance

Rhizobium Etli is one of the many soil-living bacteria able to live in conditions of nitrogen limitation due to its distinctive ability to settle onto root nodules of legumes. Like other rhizobia, it is characterized as aerobic, gram negative and able to form symbiotic relationship with legumes. In specific, rhizobium etli is the predominant bacteria found legumes such as beans.

As early as 16th century, the Rhizobium etli was discovered in the America’s, but also later identified in parts of Africa, Asia, and Europe.

Rhizobium Etli is important enough to have its genome sequence because of its unique ability to form symbiotic relationship with legumes. The host benefits by being provided nitrogen in the form of ammonia from the bacteria, while the bacteria is provided carbon and nutrients from the host.

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?
