Abstract

The promoter of the nifH gene of the fast-growing Rhizobium japonicum strain USDA 191, has been cloned. Over 4.2 kilobase pairs (kbp) of DNA were sequences (FIG. 1). Sequences encoding nifH and the 5'-end of nifD were identified, as were sequences involved in promoting operon transcription and a nifH ribosome binding site. Use of the nifH promoter to drive transcription in Rhizobium of heterologous structural genes is taught. Useful sequences and plasmids are also disclosed.
