The first known species of rhizobia, Rhizobium leguminosarum, was identified in 1889, and all further species were initially placed in the Rhizobium genus. Most research has been done on crop and forage legumes such as clover, alfalfa, beans, peas, and soybeans; more research is being done on North … See more Rhizobia are diazotrophic bacteria that fix nitrogen after becoming established inside the root nodules of legumes (Fabaceae). To express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix See more Although much of the nitrogen is removed when protein-rich grain or hay is harvested, significant amounts can remain in the soil for future crops. … See more Many other species of bacteria are able to fix nitrogen (diazotrophs), but few are able to associate intimately with plants and colonize specific structures like legume nodules.

WebJan 21, 2024 · Symbiotic interactions between legume plants and soil bacteria, collectively called rhizobia, result in the formation of nitrogen-fixing root nodules on host plant roots. … WebAug 1, 2008 · Rhizobia are Gram-negative bacteria than can elicit the formation of specialized organs, called root nodules, on leguminous host plants. Upon infection of the nodules, they differentiate into nitrogen-fixing bacteroids. An elaborate signal exchange precedes the symbiotic interaction.
WebRhizobia only associate with legumes, members of the pea family. (But not all legumes associate with Rhizobia and some that have nitrogen fixing associates may have bacteria other than Rhizobia). Taxonomy and Phylogeny Rhizobia are members of the Domain Bacteria. They are gram negative bacteria that are usually flagellated and motile.
WebRhizobia interact into mutualistic associations with the leguminous plants, inducing formation of special structures on their roots, called nodules, in which nitrogen fixation process occurs.
