Abstract

Rhizobia are a diverse group of bacteria engaged in nitrogen-fixing symbioses with leguminous plants. A prevalent interaction type results in root nodules colonized by the bacteria. Establishment and maintenance of this symbiosis involves specific recognition and coordinated differentiation of both bacterial and host cells driven by signal exchange. Characterization of this interplay reveals an impressive degree of specificity and fine-tuning resulting from million years of evolution.
