Summary
Tn5 site-directed mutagenesis was used to identify nif genes and to localize plasmid genes from A. brasilense Sp7 (ATCC29145). A DNA region covering 30 kb and containing the nitrogenase structural genes (nifHDK) has been cloned. The presence of nif genes in the 20 kb located next to nifHDK was explored by Tn5 mutagenesis and two new nif loci were identified. Homology between Rhizobium meliloti nodulation genes (nod and hsn) and Azospirillum total DNA was previously reported. A 10 kb EcoRI fragment homologous to hsn was cloned in pUC18, to yield pAB502. Preliminary experiments suggested that the hsn homologous region was located on the 90 Md plasmid contained in strain Sp7. This was confirmed after mutagenesis of pAB502 by Tn5-mob and recombination of the insertions in the 90 Md plasmid.
