    • Abstract


      A positive regulatory gene has been cloned fromAzotobacter vinelandii, using its ability to activate the expression ofnifH: lacZ fusion inE. coli. The gene has also been shown to activate the transcription from the P1 promoter ofRhizobium meliloti. It did not, however, hybridize with thenifA gene ofR. meliloti.
