This contribution is dedicated to the memory of Dr. Peter H. Graham, who through his activities worldwide raised interest in microbial gene resources as the
foundation for improved agriculture and food. For a long time he also served as the chairperson for the Subcommittee for Agrobacterium and Rhizobium of the
International Committee for the Systematics of Prokaryotes.

ABSTRACT. 

Symbiotic nitrogen fixation is the main route for sustainable input of nitrogen into ecosystems. Nitrogen fixation in agriculture can be improved by inoculation of legume crops with suitable rhizobia. Knowledge of the biodiversity of rhizobia and of local populations is important for the design of successful inoculation strategies. Soybeans are major nitrogen-fixing crops in many parts of the world. Bradyrhizobial inoculants for soybean are very diverse, yet classification and characterization of strains have long been difficult. Recent genetic characterization methods permit more reliable identification and will improve our knowledge of local populations. Forage legumes form another group of agronomically important legumes. Research and extension policies valorizing rhizobial germplasm diversity and preservation, farmer training for proper inoculant use and legal enforcement of commercial inoculant quality have proved a successful approach to promoting the use of forage legumes while enhancing biological N2 fixation. It is worth noting that taxonomically important strains may not necessarily be important reference strains for other uses such as legume inoculation and genomics due to specialization of the different fields. This article points out both current knowledge and gaps remaining to be filled for further interaction and improvement of a rhizobial commons.
