RESUMO

Rhizobium bacteria synthesize signal molecules called Nod factors that elicit responses in the legume root during nodulation. Nod factors, modified N-acylated β-(1,4)-N-acetylglucosamine, are synthesized by the nodulation (nod) gene products. We tested the ability of three Sinorhizobium meliloti nod gene products to modify Nod factor analogs with thio linkages instead of O-glycosidic bonds in the oligosaccharide backbone.
