Lack of DNA Homology between the Legume GLYCINE MAX and Its Symbiotic Rhizobium Bacteria.

ABSTRACT

Any common genes of Glycine max and its symbiotic rhizobium bacteria 61A76 represent less than 0.6% of the bacterial genome. Thus, if any sizable exchange of DNA between host and symbiote occurs it must result in unstable DNA association which is lost with subsequent generations.
