Structural determination of the lipo-chitin oligosaccharide nodulation signals produced by Rhizobium fredii HH103.
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.
