title: Rhizobium leguminosarum mutants incapable of normal extracellular polysaccharide production.
abstract: Mutants of Rhizobium leguminosarum which are deficient in normal polysaccharide production have been isolated and characterized. A correlation between diminished production of extracellular polysaccharide and reduced infection and nodulation efficiency has been observed.
