Abstract
Recombinant DNA clones according to the invention contain a host range gene of B. japonicum which is contained within a 3.3 kb HindIII restriction fragment from the B. japonicum chromosome. Mutations to this gene change the ability of the bacteria to nodulate different plants. In one example, a Tn5 insertion to this region caused the strain to lose its ability to nodulate siratro, but nodulation of soybeans was unaffected. This gene may be manipulated to extend or restrict the host range of the strain for agricultural purposes.
