R gene-controlled host specificity in the legume-rhizobia symbiosis.
Leguminous plants can enter into root nodule symbioses with nitrogen-fixing soil bacteria known as rhizobia. An intriguing but still poorly understood property of the symbiosis is its host specificity, which is controlled at multiple levels involving both rhizobial and host genes. It is widely believed that the host specificity is determined by specific recognition of bacterially derived Nod fa...
متن کاملUpdate on MicroRNAs in the Rhizobia Legume Symbiosis MicroRNAs in the Rhizobia Legume Symbiosis
Legumes are agronomically valuable crops for food and fodder production worldwide because they are rich in protein, oil, fiber, and micronutrients. In addition, legumes require less chemical fertilizer than other major crop plants since they can assimilate some nutrients through symbiotic interactions with soil microbes. These relationships are mutually beneficial for the partners because the p...
متن کاملSpecificity in Legume-Rhizobia Symbioses
Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N₂) via symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia symbioses in field soils was reviewed and genotypically characterised rhizobia related to the taxonomy of the legumes from which they were isolated. The Leguminosae was divided into three sub-families, the Caesalpinioideae, ...

متن کاملEvolutionary Dynamics of Nitrogen Fixation in the Legume–Rhizobia Symbiosis
The stabilization of host-symbiont mutualism against the emergence of parasitic individuals is pivotal to the evolution of cooperation. One of the most famous symbioses occurs between legumes and their colonizing rhizobia, in which rhizobia extract nutrients (or benefits) from legume plants while supplying them with nitrogen resources produced by nitrogen fixation (or costs). Natural environmen...
