title: Structural determination of the lipo-chitin oligosaccharide nodulation signals produced by Rhizobium fredii HH103.
abstract: Rhizobium fredii HH103 produces extracellular signal molecules that are able to induce deformation of root hairs and nodule organogenesis of soybean. This strain produces a large variety of nodulation factors, consisting of a linear backbone of GlcNAc with different degrees of polymerization, bearing on the non-reducing residue various different N-acyl residues. The reducing terminal residue is 2-O-methylfucosylated at position 6. Several analogous molecules substituted with fucose were also detected.
