Exogenous suppression of the symbiotic deficiencies of Rhizobium meliloti exo mutants.

Journal of bacteriology - 1 May 1992

Urzainqui A, Walker G C

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 form of this exopolysaccharide, and in this report we show that the symbiotic deficiencies of two exo mutants of R....
