title: Bradyrhizobia from wild Phaseolus, Desmodium, and Macroptilium species in northern Mexico.
abstract: rRNA genetic markers were analyzed in 97 isolates of nodule bacteria from six legume species in Chihuahua, Mexico. The most common genotypes were widely shared across host species and had 16S rRNA sequences identical to those of strains from an eastern North American legume (Amphicarpaea) that are closely related to Bradyrhizobium elkanii.
