nodA andnifH phylogenies forCupriavidus nodule bacteria from native legumes in Texas and Costa Rica grouped all strains into a single clade nested among neotropicalBurkholderia strains. Thus,Cupriavidus symbiotic genes were not acquired independently in different regions and are derived from otherBetaproteobacteria rather than from α-rhizobial donors.
