Rhizobium etli bv. phaseoli str. IE4803

Rhizobium etli bv. phaseoli str. IE4803 is a Gram-negative, rod-shaped bacterium that exists primarily in a host-associated habitat. This strain is characterized by its arrangement in singles and demonstrates an aerobic metabolism, indicating its reliance on oxygen for growth and energy production. As a member of the Rhizobium genus, R. etli bv. phaseoli str. IE4803 is known for its symbiotic relationships with legumes, particularly in the root nodules of Phaseolus vulgaris, more commonly known as common beans. This interaction is crucial for nitrogen fixation, where the bacterium converts atmospheric nitrogen into a form that is accessible to plants, thereby enhancing soil fertility and supporting plant growth. The ability of R. etli bv. phaseoli str. IE4803 to thrive in aerobic environments suggests its adaptation to the oxygen-rich conditions found in root nodules and surrounding soil. This adaptation may also play a role in its metabolic processes and overall fitness within its plant host. Understanding the traits of this strain can provide insights into its contributions to sustainable agricultural practices, particularly in the cultivation of nitrogen-efficient legume crops.
