| lipopolysaccharide profiles from nodules as markers of bradyrhizobium strains nodulating wild legumes. | to develop the use of electrophoretic lipopolysaccharide profiles for bradyrhizobium strain identification, we studied the feasibility of using electrophoresis of whole legume nodule homogenates to obtain distinctive lipopolysaccharide profiles. the electrophoretic patterns were the same whether we used nodule extracts, bacteroids, or cultured bacteria as samples, and there was no evidence of changes in the ladder-like pattern during the nodulation process. to assess the reliability of using lip ... | 1998 | 16349529 |
