title: Restriction mapping of deletions in the nif region of the Klebsiella pneumoniae chromosome.
abstract: Chromosomal DNA restriction fragments carrying the nitrogen fixation (nif) and his genes of Klebsiella pneumoniae were identified in hybridization experiments using a plasmid derived from pRD1 as a radioactive probe. Restriction mapping of 26 genetically characterized chromosomal nif deletions provided a map showing the physical location of nif genes along the chromosome.
