Abstract

Rhizobial ferredoxin genes and proteins are provided. Rhizobial ferredoxins are useful to enhance the nitrogenase systems of rhizobia. Useful rhizobial ferredoxin diagnostic segments are also provided comprising DNA sequences encoding the characteristic ferredoxin cysteine residue patterns. Exemplied rhizobial ferredoxin genes are fixX of Rhizobium trifolii and Rhizobium meliloti Between fixC and nifA, fixY of Rhizobium meliloti down stream from nifB, and frxA of Bradyrhizobium japonicum.
