This work investigated the microbial content of nodules from alders to determine how many ribotypes of Frankia were present and which, if any, other bacteria existed within nodes from the nodules. The bacterial content of alder nodules was investigated by 454 sequencing of 16S rDNA genes. Over half of the sequences were from a single ribotype of Frankia, with nearly all other sequences coming from the chloroplast of the host plant, and other sequences (including other ribotypes of Frankia) being at < 1%. It is concluded that a single ribotype of Frankia is the major, although not unique, bacterium present in an individual lobe from an alder nodule.
