Specificity 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 کاملChoice of hydrogen uptake (Hup) status in legume-rhizobia symbioses
The H(2) is an obligate by-product of N-fixation. Recycling of H(2) through uptake hydrogenase (Hup) inside the root nodules of leguminous plants is often considered an advantage for plants. However, many of the rhizobium-legume symbioses found in nature, especially those used in agriculture are shown to be Hup(-), with the plants releasing H(2) produced by nitrogenase activity from root nodule...
متن کاملR 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 کاملLipopolysaccharides in Rhizobium-legume symbioses.
The establishment of nitrogen-fixing symbiosis between a legume plant and its rhizobial symbiont requires that the bacterium adapt to changing conditions that occur with the host plant that both promotes and allows infection of the host root nodule cell, regulates and resists the host defense response, permits the exchange of metabolites, and contributes to the overall health of the host. This ...
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...
