Location of nif genes on large plasmids in Rhizobium strains isolated from legume tree root nodules

Abstract:

The presence of plasmids in Rhizobium strains isolated from legume tree root nodules has been studied. Bacteria isolated from Acacia melanoxylon, A. cyanophylla, Prosopis chilensis and Sophora microphylla harbour 2 to 5 plasmids of an Mr higher than 115 · 106. Hybridization experiments have shown DNA homology between plasmid pID1 (R. meliloti 41 nifH and D genes) and one of the plasmids in each of the bacteria studied. © 1984.
