Monophyly of nodA and nifH genes across Texan and Costa Rican populations of Cupriavidus nodule symbionts.

ABSTRACT: nodA and nifH phylogenies for Cupriavidus nodule bacteria from native legumes in Texas and Costa Rica grouped all strains into a single clade nested among neotropical Burkholderia strains. Thus, Cupriavidus symbiotic genes were not acquired independently in different regions and are derived from other Betaproteobacteria rather than from alpha-rhizobial donors.
