Abstract: | Abstract Lipopolysaccharide (LPS) patterns were obtained from fast-growing Rhizobium strains after silver staining of proteinase K treated cells lysates, run in SDS-PAGE. The rhizobia came from root nodules of Acacia senegal and Prosopis chilensis , collected in differents part of the Sudan. The LPS profiles of all strains were typical of rhizobia. Two different LPS region with lower and higher electrophoretic mobility (region I and region II, respectively) coulld be dinguished in the gels, and based on the profiles the strains were divided into three groups. Strains isolated from A. senegal showed a wider range of different profiles than strains isolated from P. chilensis , even though the plants belong to the same cross-infection group. Otherwise there was no clear correlation between the taxonomic relatedness or site of isolation of the strains and their LPS profiles. |
