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. (wikipedia.org)
A soil isolate of Rhizobium leguminosarum by trifolii was marked with a lux CDABE gene cassette to enable the expression of bioluminiscence. (elsevierpure.com)
Bacteria4
Most of legume species, plants in the family Fabaceae (Leguminosae), live in symbiotic relationships with nitrogen-fixing bacteria (rhizobia bacteria). (robaid.com)
In the previous section (section 5) it was noted that the process of BNF takes place after a legume root has been infected by soil bacteria of the genus Rhizobium . (oregonstate.edu)
The bacteria that is most often used to inoculate forage crops is bacteria in the genus Rhizobium . (oregonstate.edu)
Moreover, legumes specifically interact with nitrogen-fixing Rhizobium bacteria to establish a symbiosis in which atmospheric nitrogen is fixed by the symbiotic form of rhizobia and delivered to the plant partner. (biomedcentral.com)

Glutathione affects the transport activity of Rhizobium leguminosarum 3841 and is essential for efficient nodulation. (ox.ac.uk)
As glutathione (GSH) plays an essential role in growth and symbiotic capacity of rhizobia, a glutathione synthetase (gshB) mutant of Rhizobium leguminosarum biovar viciae 3841 (Rlv3841) was characterised. (ox.ac.uk)

With a long break period recommended between pea crops, uncertainty over surviving rhizobia levels and the effectiveness of native populations or surviving strains at facilitating N 2 fixation, supplementary inoculant is a cost-effective way to ensure maximum N 2 fixation and yield. (manitobapulse.ca)
Compatible rhizobia strains are essential for nodulationand biological nitrogen fixation (BNF) of hairy vetch(Vicia villosa Roth, HV). (uncg.edu)
Nodulation4
Fivegroups of similar HV genotypes were inoculated with soildilutions from six paired fields, three with 10-year HV cultivationhistory (HV+) and three with no history (HV-), andused to determine efficiency of rhizobia nodulation and BNF.Nodulation was equated to nodule number and mass, BNF toplant N and Rhizobium leguminosarum biovar viceae (Rlv)soil cell counts using qPCR to generate an amplicon of targetedRlv nodD genes. (uncg.edu)
Although hairy vetch rhizobia occur naturally in soils, pastcultivation of HV was shown in this study to enhance nodulationgene-carrying Rlv population size and/or efficiency ofrhizobia capable of nodulation and N fixation. (uncg.edu)
Absence of the specific Rhizobium species or biovar needed for maximum infection and nodulation may occur if the forage crop being grown has not been grown in the soil for a number of years. (oregonstate.edu)
For the nodulation experiments, Rhizobium leguminosarum bv. (biomedcentral.com)

To indicate which species or biovars of rhizobia effectively nodulate which legumes, scientists have developed so called 'cross inoculation groups. (oregonstate.edu)
The term 'Cross inoculation groups' refers to a classification scheme used to designate which groups of forage legumes are successfully inoculated by which species or biovars of rhizobia. (oregonstate.edu)
For example, the cross inoculation group for the species of rhizobia known as Rhizobium meliloti is alfalfa ( Medicago sativa ) and sweetclover ( Melilotus spp. (oregonstate.edu)
Nitrogen4
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. (wikipedia.org)
One of the largest contributions to biologically available nitrogen comes from the reduction of N(2) to ammonia by rhizobia in symbiosis with legumes. (nih.gov)
Field peas can fix atmospheric nitrogen (N 2 ) through a symbiotic relationship with Rhizobium leguminosarum . (manitobapulse.ca)
Rhizobium, Blue-green algae, and Azolla are all types of biofertilizers that help the soil to contain nitrogen. (iasbook.com)
There are at least two reasons why this may be the case: 1) Non optimal soil conditions, and 2) Absence of the specific Rhizobium species or biovar needed for the forage crop in question. (oregonstate.edu)
Furthermore, it has been determined that different forage legumes require different species or even different biovars within species of Rhizobium for successful formation of nodules. (oregonstate.edu)
For example, a Rhizobium species or biovar that will successfully nodulate alfalfa may not effectively inoculate some clovers. (oregonstate.edu)

Fixation2
However, metabolic exchange must be more complex, because effective N(2) fixation by Rhizobium leguminosarum bv viciae bacteroids requires either one of two broad-specificity amino acid ABC transporters (Aap and Bra). (nih.gov)
