ABSTRACT
We determined the structures of Nod factors produced by six different Bradyrhizobium sp. strains nodulating the legume tree Acacia albida (syn. Faidherbia albida). Compounds from all strains were found to be similar, i.e., O-carbamoylated and substituted by an often sulfated methyl fucose and different from compounds produced byRhizobium-Mesorhizobium-Sinorhizobium strains nodulating other species of the Acaciae tribe.
