Multilocus sequence analysis of the genus Bradyrhizobium.
The use of multilocus sequence analysis (MLSA) for the taxonomy of Bradyrhizobium was assessed. We compared partial sequences for atpD, recA, gyrB, rpoB and dnaK for a set of reference strains… Expand

A New Species of Devosia That Forms a Unique Nitrogen-Fixing Root-Nodule Symbiosis with the Aquatic Legume Neptunia natans (L.f.) Druce
ABSTRACT Rhizobia are the common bacterial symbionts that form nitrogen-fixing root nodules in legumes. However, recently other bacteria have been shown to nodulate and fix nitrogen symbiotically… Expand
