Rhizobium etli CFN 42

Rhizobium etli CFN 42 is a Gram-negative, rod-shaped bacterium that plays a crucial role in the symbiotic relationship with the leguminous plant Phaseolus vulgaris, commonly known as the common bean. This bacterium is categorized as an aerobe, indicating its requirement for oxygen to grow and thrive. It possesses flagella, which contributes to its mobility, allowing it to navigate its host environment effectively. R. etli CFN 42 exhibits a mesophilic temperature range, thriving optimally in moderate temperatures typical of its natural habitat. The bacterium is characterized by a complex genomic structure with three replicons and is surrounded by two membranes, a feature typical of Gram-negative bacteria. Importantly, R. etli CFN 42 does not form spores, which suggests a continuous growth strategy in its symbiotic association rather than reliance on sporulation for survival in fluctuating environments. The biotic relationship between R. etli CFN 42 and Phaseolus vulgaris is particularly noteworthy, as it facilitates nitrogen fixation, a critical process that enhances soil fertility and supports plant growth. This symbiosis not only benefits the host plant but also contributes to the overall health of the ecosystem by improving nutrient cycling. The genetic information of R. etli CFN 42 can be accessed through multiple accession numbers, including NC_004041.2, NC_007762.1, and NC_007766.1, which provide valuable resources for further research into its biological functions and ecological roles.
