Phylogenetic distribution of OTUs for Bacteroidetes based on the 16S rRNA gene sequences of the clone libraries and isolate collections derived from field-grown potato plants. The dendrogram indicates the phylogenetic relationships among the representative sequences of OTUs (defined by ≥97% identity). The table indicates the relative abundance of clones or isolates belonging to each OTU in each library or collection and the results of a BLAST search using the representative sequences. Shading indicates OTUs described in the main text.
