Rhizobium leguminosarum - Wikipedia
Rhizobium leguminosarum is a bacterium which lives in a mutualistic symbiotic relationship with legumes, and has the ability to fix free nitrogen from the air. [2] R. leguminosarum has been very thoroughly studied—it has been the subject of more than a thousand publications.

Rhizobia are nitrogen-fixing bacteria classified and characterized by different systems. Beijerinck was able to isolate and cultivate a microorganism, named Bacillus radiocicola, from the nodules of legumes in 1888.
Rhizobia: from saprophytes to endosymbionts - Nature
2018年1月30日 · The Rhizobium leguminosarum prsDE genes are required for secretion of several proteins, some of which influence nodulation, symbiotic nitrogen fixation and exopolysaccharide modification. Mol...
Rhizobial–Host Interactions and Symbiotic Nitrogen Fixation in …
In legumes, a group of bacteria collectively referred to as rhizobia enzymatically convert atmospheric nitrogen into organic form through a symbiotic process (symbiotic N fixation, SNF) in the host roots. The grain legumes account for 27% …
Defining the Rhizobium leguminosarum Species Complex
2021年1月18日 · Bacteria currently included in Rhizobium leguminosarum are too diverse to be considered a single species, so we can refer to this as a species complex (the Rlc). We have found 429 publicly available genome sequences that fall within the Rlc and these show that the Rlc is a distinct entity, we …
The genome of Rhizobium leguminosarum has recognizable …
2006年7月4日 · Rhizobium leguminosarum is an α-proteobacterial N2-fixing symbiont of legumes that has been the subject of more than a thousand publications. Genes for the symbiotic interaction with plants are well studied, but the adaptations that allow survival and growth in the soil environment are poorly understood.
Rhizobium leguminosarum - an overview | ScienceDirect Topics
The bacterium Rhizobium leguminosarum colonizes the root nodules of legumes where it fixes atmospheric nitrogen, converting it to ammonia. This symbiosis is one of the best-characterized plant–bacteria relationships in nature and is of great agricultural and economic significance.
Genome-Scale Metabolic Modelling of Lifestyle Changes in Rhizobium …
2022年1月11日 · We reconstructed a genome-scale metabolic model for Rhizobium leguminosarum and integrated the model with transcriptome, proteome, metabolome, and gene essentiality data to investigate nutrient uptake and metabolic fluxes characteristic of these different lifestyles.
