Nitrogen-fixing symbioses between bacteria and plants are major nitrogen contributors to the terrestrial biosphere. The Rhizobium–legume interaction is the best known and is agronomically the most important one. Several alpha- and betaproteobacterial species (rhizobia) can infect legume roots via root hair or crack invasion, preceded by signal exchange in the rhizosphere and followed by signal transduction in the root, resulting in the construction of a nitrogen-fixing root nodule.
