Bradyrhizobium sp. Strains that nodulate the leguminous tree Acacia albida produce fucosylated and partially sulfated nod factors.
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 by Rhizobium-Mesorhizobium-Sinorhizobium strains nodulating other species of the Acaciae tribe.
