Abstract excerpt
Two transposon Tn5-induced mutants of wild-type broad-host-range Rhizobium sp. GRH2 were isolated and found to harbour different alterations in surface polysaccharides. These mutants, designated GRH2-14 and GRH2-50, induced a few, empty nodules on Acacia and lost the ability to nodulate most host herbaceous legumes. Whereas mutant GRH2-14 produces an acidic exopolysaccharide (EPS) similar to the wild-type, the...
