Over the years, the term “rhizobia” has come to be used for all the bacteria that are capable of nodulation and nitrogen fixation in association with legumes but the taxonomy of rhizobia has changed considerably over the last 30 year. Recently, several non-rhizobial species belonging to alpha and beta subgroup of Proteobacteria have been identified as nitrogen-fixing legume symbionts. Here we provide an overview of the history of the rhizobia and the widespread phylogenetic diversity of nitrogen-fixing legume symbionts
