Abstract Lipid A's from two Bradyrhizobium species and from the phylogenetically closely related species “Pseudomonas carboxydovorans” were found to contain 2,3-diamino-2,3-dideoxy-glucose as lipid A backbone sugar. In contrast, three representatives of the genus Rhizobium, as well as the phylogenetically related species Agrobacterium tumefaciens, contain solely glucosamine as lipid A backbone sugar. These findings suppor independent studies on the phylogenetical relatedness based on 16S rRNA-data of the genus Bradyrhizobium with “Pseudomonas carboxydovorans“ and Rhodopseudomonas palustris, which form a tight phylogenetical cluster and which all contain the 2,3-diamino-2,3-dideoxy-glucose-containing lipid A. The relatedness of these species to the glucosamine-containing species of the genus Rhizobium and to Agrobacterium tumefaciens is rather distant as documented by 16S rRNA studies.
