Taxonomy of Legume Nodule Bacteria (rhizobia) and agrobacteria: species with standing in nomenclature

This page provides information on the current taxonomic status of validly published alpha- and beta-rhizobial/agrobacterial species, organized by classes and genera.

 

Whenever possible, a hyperlink is provided to the online abstract of the primary reference describing a species. When such an abstract is not available, the reader is referred to the genus hyperlink, where full bibliographic details are provided at J.P. Euzéby's "List of Prokaryotic Names with Standing in Nomenclature."

 

A related site (Rhizobia taxonomy) maintained by Dr. Bevan Weir from New Zealand also provides an up-to-date list of rhizobial taxa with standing in nomenclature.
