Host-Symbiont Interactions 1



The sequence of the glycosyl residues and the anomeric configurations of the glycosyl linkages of the acidic polysaccharides secreted by Rhizobium leguminosarum 128c53, Rhizobium leguminosarum 128c63, Rhizobium trifolii NA30, and Rhizobium trifolii 0403 have been determined. All four polysaccharides were found to have the following glycosyl repeating-unit structure, where galactosyl is Gal, glucosyl is Glc, glucuronosyl is GlcA, and pyruvyl is Pyr: [Formula: see text] Each of the glycosyl residues of these polysaccharides was determined to be in the d configuration and in the pyranose ring form. These results add support to the proposal that R. leguminosarum and R. trifolii have a particularly close genetic relationship. The significance of these results with regard to the possible function of these polysaccharides in the nodulation process is discussed.
