Conflicting phylogeographic patterns in rRNA and nifD indicate regionally restricted gene transfer in Bradyrhizobium.

Microbiology (Reading, England) - 1 Aug 2002

Abstract excerpt

Major differences in evolutionary relationships of the 16S rRNA gene and the nitrogenase alpha-subunit gene (nifD) were observed among 38 strains of Bradyrhizobium sp. nodule bacteria from North America, Central America, Asia and Australia. Two lineages were evident in the 16S rRNA phylogeny representing strains related to Bradyrhizobium japonicum (29 isolates) or Bradyrhizobium elkanii (9 isolates). Both clades...
