Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an endosymbiotic nitrogen-fixing association with roots of legumes and Parasponia.
Bradyrhizobium is a genus of Gram-negative soil bacteria, many of which fix nitrogen. Nitrogen fixation is an important part of the nitrogen cycle. Plants cannot use atmospheric nitrogen (N2); they must use nitrogen compounds such as nitrates.
Herbaspirillum lusitanum is a nitrogen-fixing bacterium found in root nodules of common beans. Phylogenetic analyses have shown this bacterium belongs to the genus Herbaspirillum. H. lusitanum lacks the nif gene. A nodD-like gene is present, but no other nod genes have been identified. The lack of nif and nod genes suggests H. lusitanum is an opportunistic bacterium capable of colonizing root nodules, but is unable to fix nitrogen.
Sinorhizobium fredii is a nitrogen fixing bacteria of the genus Sinorhizobium. It is a fast-growing root nodule bacteria. Sinorhizobium fredii exhibit a broad host-range and are able to nodulate both determinant hosts such as soy as well as indeterminate hosts including the pigeon pea. Because of their ease of host infection there is interest in their genetics and the symbiotic role in host infection and nodule formation.
Pararhizobium giardinii is a Gram negative root nodule bacteria. It forms nitrogen-fixing root nodules on legumes, being first isolated from those of Phaseolus vulgaris.
Rhizobium gallicum is a Gram-negative root-nodule bacterium. It forms nitrogen-fixing root nodules on legumes, being first isolated from those of Phaseolus vulgaris.
Mesorhizobium tianshanense, formerly known as Rhizobium tianshanense, is a Gram negative species of bacteria found in the root nodules of many plant species. Its type strain is A-1BS.
Bradyrhizobium canariense is a species of legume-root nodulating, endosymbiont nitrogen-fixing bacterium. It is acid-tolerant and nodulates endemic genistoid legumes from the Canary Islands. The type strain is BTA-1T.
Mesorhizobium plurifarium is a species of root nodule bacteria first isolated from Acacia species in Senegal. Its type strain is ORS 1032.
Mesorhizobium amorphae is a species of root nodule bacteria first isolated from Amorpha fruticosa species in China. It is purported to be native to American soil. Its genome has been sequenced. Its type strain is ACCC 19665.
Rhizobium mongolense is a Gram negative root nodule bacteria, which nodulates and forms nitrogen-fixing symbioses with Medicago ruthenica. Its type strain is USDA 1844.
Ochrobactrum lupini is a non-rhyzobial root-nodulating bacteria. It nodulates Lupinus albus, hence its name. Strain LUP21T is the type strain.
Mesorhizobium chacoense is a gram-negative, aerobic, non-spore-forming, motile bacteria from the genus of Mesorhizobium which was isolated from root nodules of Prosopis alba in the Chaco Arido region in Argentina.
Mesorhizobium ciceri is a gram-negative, nitrogen-fixing motile bacteria from the genus of Mesorhizobium which was isolated from Chickpea nodules of Cicer arietinum in Spain. Rhizobium cicero was transferred to Mesorhizobium ciceri.
Mesorhizobium mediterraneum is a bacterium from the genus Mesorhizobium, which was isolated from root nodule of the Chickpea in Spain. The species Rhizobium mediterraneum was subsequently transferred to Mesorhizobium mediterraneum. This species, along with many other closely related taxa, have been found to promote production of chickpea and other crops worldwide by forming symbiotic relationships.
Bradyrhizobium betae is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacterium first isolated from the roots of Beta vulgaris, hence its name. It is slow-growing an endophytic. The type strain is PL7HG1T.
Devosia neptuniae is a nitrogen-fixing bacteria that nodulates Neptunia natans. It is Gram-negative, strictly aerobic short rod-shaped and motile by a subpolar flagellum. The type strain of D. neptuniae is LMG 21357T.
Phyllobacterium endophyticum is a bacterium from the genus of Phyllobacterium which was isolated from a nodule of the plant Phaseolus vulgaris in Northern Spain.
