Biological nitrogen fixation (BNF) is easily the most studied microbial process applied to agriculture. It consists of the reduction of atmospheric dinitrogen (N2), unavailable to higher plants, into ammonium (NH4+), an assimilable form of this nutrient. The BNF process is performed solely by microorganisms, the majority inhabiting the soil ecosystem, and is considered to be the most relevant component of the global nitrogen cycle (Ishizuka, 1992). The best known diazotrophs (dinitrogen fixing bacteria) are rhizobia, which are able to establish a symbiotic relationship with plants of the family Leguminosae, hereby called legumes. This symbiosis is characterized by a highly specific association between plant and bacteria. Particular varieties of legume species recognize specific strains of rhizobia, which are able to infect the legume roots. This process triggers the expression of certain plant genes, resulting in the development of nodules around the site of invasion. In the interior of the nodules the bacteria undergo morphological and physiological transformations, becoming nitrogen fixing bacteroides and supplying the plant with nutrient in exchange for carbon-rich material derived from plant photosynthesis. |
