Transfer from Rhizobium japonicum to Azotobacter vinelandii of genes required for nodulation

R J Maier et al. J Bacteriol. 1978 Jun.

Abstract

A mutant strain of Azotobacter vinelandii that is unable to fix N2 (Nif-) was transformed to Nif+ with DNA from Rhizobium japonicum. Of 50 Nif+ transformants tested, 3 contained the O antigen-related polysaccharide that is present on the cell surface of a nodulating R. japonicum strain, but is absent from a non-nodulating mutant strain.
