• Cape flora
• Nitrogenase
• nifH

Gene sequences assigned nodular strains to both cluster I (Alnus host-infection group) and cluster III (Elaeagnus host-infection group), with sequences from both groups recovered from three hosts: M. intergra, M. diversifolia and M. quercifolia. Cluster I sequences were found in nodules from acidic soils exclusively. Frankia strains representing both groups were isolated and characterized by 16S rRNA and nifH analysis.
This study is the first to investigate the diversity of Frankia associated with endemic African actinorhizal species in their natural habitats, and to report isolation of Frankia strains from African Morella.
