Abstract excerpt

The acidic exopolysaccharide (EPS I) produced by Rhizobium meliloti during symbiosis with Medicago sativa has been shown to be required for the proper development of nitrogen-fixing nodules. Cloned DNA from the exo region of R. meliloti is shown to stimulate production of the low-molecular-weight...
