Legume2

• and its nodule isolates Azorhizobium johannae with other legume hosts and rhizobia. (wikipedia.org)
• The rhizobia-legume symbioses exhibit variation in symbiotic performance as measured by plant yield, nodulation and nitrogenase activity. (benthamscience.com)

Meliloti2

• The three gene products were very similar to the corresponding polypeptides of Rhizobium meliloti. (hal.science)

Bacteria2

• Azorhizobium doebereinerae is a species of bacteria in the family Xanthobacteraceae. (wikipedia.org)
• Rhizobia are composed of specific groups of bacteria that have the ability to induce symbiotic nitrogen-fixing nodules on the roots or stems of leguminous plants. (benthamscience.com)

Nodules1

• How are nodules formed in Rhizobium? (biokaryon.com)

PGPR1

• Rhizobia are important members of plant-growth-promoting rhizobacteria (PGPR) that exert the positive effects on plant growth via direct and indirect mechanisms. (benthamscience.com)

Symbiotic1

• It has also been found that symbiotic variation is connected to some characteristics of rhizobia including serological and morphological phenotypes, tolerance to stresses, host range, plasmid profile as well as some cryptic plasmids. (benthamscience.com)

Species2

• The classification of rhizobia is becoming increasingly complex and is revised periodically because of new findings that propose new genera and new species. (benthamscience.com)
• The results obtained from numerical analysis support the proposal of several novel species of rhizobia. (benthamscience.com)

Nitrogen1

• Rhizobia are of enormous agricultural and economic values because they provide the major source of nitrogen input in agricultural soils. (benthamscience.com)

Found1

• Rhizobia in different serogroups have been found predominant among field populations. (benthamscience.com)

Sinorhizobium1

• Bacteria belonging to the genera Rhizobium, Sinorhizobium, Azorhizobium, and Mesorhizobium grow in the soil in free-living conditions, and in symbiosis associated with the root of legumes as nitrogen-fixing organisms. (conicet.gov.ar)

Genera1

• The classification of rhizobia is becoming increasingly complex and is revised periodically because of new findings that propose new genera and new species. (eurekaselect.com)

Legume hosts1

• and its nodule isolates Azorhizobium johannae with other legume hosts and rhizobia. (wikipedia.org)

Symbiosis1

• globally, ~33-46 Tg of N year −1 is contributed by the legume-rhizobia symbiosis ( Herridge, 2008 ). (frontiersin.org)

Legumes2

• The symbiotic interaction between rhizobia and legumes that leads to nodule formation is a complex chemical conversation involving plant release of nod -gene inducing signal molecules and bacterial secretion of lipo-chito-oligossacharide nodulation factors. (frontiersin.org)
• The Rhizobium strains isolated from legumes plant Mimosa pudica L and this strain was mutated by using UV radiation. (ijpsr.com)

Isolates1

• In our laboratory we have characterized acid-tolerant isolates of rhizobia that have an extended host range for nodulating alfalfa, the common bean, and Leucena leucocephala (1). (conicet.gov.ar)

Plasmids2

• Rhizobia could borne plasmids whose role is not currently understood, referred as accessory plasmids. (conicet.gov.ar)
• The characterization of the Or-like plasmids will be valuable in the elucidation of mechanisms involved in the evolution and diversification of the alfalfa- and bean-nodulating rhizobia. (conicet.gov.ar)

Strain1

• the compared to two strains of Rhizobium , mutated strain are high growth and yield when compared to normal stain. (ijpsr.com)

Characterization1

• We were interested in the characterization of the plasmid gene pool present in Medicago-nodulating rhizobia in order to ascertain the plasmid-related evolutionary relationships within this group of rhizobia. (conicet.gov.ar)

Characteristics1

• Serological techniques are the most specific methods for identifying rhizobia based on natural marker characteristics. (eurekaselect.com)

Members1

• Rhizobia are important members of plant-growth-promoting rhizobacteria (PGPR) that exert the positive effects on plant growth via direct and indirect mechanisms. (eurekaselect.com)

Growth1

• Some of these metabolites can enhance plant growth via the suppression of the deleterious effects of other antagonistic molecules, as exemplified by the reduction in the deleterious effect of ethylene by ACC deaminase synthesized by rhizobia. (frontiersin.org)

Analysis1

• Phenotypic diversity of rhizobia has been studied by several methods, particularly numerical analysis, enzyme pattern and serological study. (eurekaselect.com)
