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.[2]

Morphology[]

Rhizobium leguminosarum is a Gram-negative, motile, rod-shaped, aerobic bacterium.[3]

Common biovars[]

Rhizobium leguminosarum biovar trifolii, and R. leguminosarum biovar viciae are the most commonly studied biovars of R. leguminosarum, with certain studies seemingly treating R. trifolii as its own species.[4]

Fatty acid synthesis[]

Rhizobium leguminosarum's acyl carrier protein differs from most ACPs by having a C-terminus extension. This ACP is also used in the synthesis of unusually long ACPs which themselves are then used in the synthesis of the R. leguminosarum nod factor.[5]

Uses[]

Research has been carried out into the role that R. leguminosarum could play in promoting growth of canola and lettuce.[6]
