Host-Plant Invasion by Rhizobia
2000Colonization of legume roots by compatible soil bacteria of the genera Azorhizobium, Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium (collectively known as rhizobia) leads to the formation of specialized nitrogen-fixing organs called nodules. Signals produced by both partners control specificity. Flavonoids found in root exudates trigger the

Nitrogenase — Hydrogenase interrelationships in Rhizobia
Biochimie, 1978A review is given of the properties of the hydrogenase present in Rhizobium bacteriods together with a discussion and evidence of the function of the enzyme in relationship to nitrogen fixation. The efficiency with which nodules fix nitrogen i.e. the amount of hydrogen evolved as a ratio of the total electron flow through nitrogenase, is considered and

Photosynthetic N2-fixing Rhizobia
1991An isolate from a stem nodule on the legume Aeschynomene indica, rhizobial strain BTAi 1, is pink when cultured in the light with a photo-period of 16 h. The absorption spectra of whole and extracted cells of BTAi 1 indicate the presence of bacteriochlorophyll and carotenoid pigments.

The symbiotic nitrogen fixation (SNF) with legumes is the primary source of biologically fixed nitrogen for agricultural system. It is performed by a group of bacteria commonly called rhizobia. It is characterized by a host preference, and the differences among symbioses between rhizobial strains and legume genotypes are related to infection, nodule ...

Cytokinin Production by Rhizobia
1991Culture media from a number of rhizobial strains, including the type-strains of 8 major cross-inoculation groups, were analyzed for cytokinin content. Cytokinins were partially purified by chromatography on Amberlite XAD-2, then on Sephadex LH-20. The tobacco callus assay, HPLC and/or immunoassay were used for cytokinin analysis.

Rhizobia and Legume Nodulation Genes
2013Most legume plants are able to enter into a symbiotic relationship with nitrogen-fixing soil bacteria commonly referred to as rhizobia. This interaction leads to the formation of novel root organs called nodules in which the rhizobia are housed. The symbiosis provides the legume host with a tremendous competitive advantage over other plant species that

The nitrogen-fixing bacteria that are capable of nodulating legumes are called rhizobia. Recycling of nitrogen through natural processes, i.e. symbiotic nitrogen fixation is considered as the most appropriated method for the long-term management of nutrients.

Identifying Rhizobia by Immunoblot
1994The immunoblot technique is an enzymatic immunoassay for the detection of antigens at picogram (10–12) levels. Like the indirect enzyme-linked immunosorbent assay (ELISA), the method described here can be used with a commercially prepared secondary anti-body-enzyme conjugate. In principle, the ELISA and the immunoblot assay are similar.

Abstract Most of the legumes have the ability to establish a dinitrogen-fixing association with bacteria defined as rhizobia. The legume crops will benefit from this symbiosis only when the plant roots encounter, during their development, compatible and efficient rhizobia that can induce the formation of fully effective nodules.

Nitrogen oxide reduction in rhizobia
2004Rhizobia are soil bacteria typically able to symbiotically interact with legume plants to produce nitrogen fixing root nodules. While all rhizobia were once placed under the same genus, Rhizobium, nowadays the classification of rhizobia using molecular analysis has revealed a more complex relationship among strains.
