Interpretive Summary: The aquatic legumes of the genus Neptunia in Senegal are nodulated by rhizobial bacteria of the genus Allorhizobium, which is very closely related to Agrobacterium and has a similiar mode of entry into the plant. This information will be used by bacteriologists to investigate the usefulness of these organisms in sustainable agriculture due to their nitrogen fixation ability.

Technical Abstract: There is one Rhizobial species in the genus Allorhizobium and that is A. undicola, highly related to Agrobacterium vitis. A. undicola nodulates the aquatic legume Neptunia natans. These nitrogen fixing microsymbionts are very beneficial for plant growth, yet they exhibit "wound-entry" or crack entry very similar to the highly related pathogenic species of Agrobacterium (96.2% similarity). These interesting micro-organisms will be of interest to bacteriologists.
