Figure 2. Denaturing gradient gel electrophoresis of thaumarchaeal 16S rRNA gene amplicons from freshwater (F1–F6) and marine (M) aquarium, with an unweighted pair group method with arithmetic mean (UPGMA) dendrogram representing distances based on Pearson correlations of fingerprint densitometric curves.

Fingerprints have been normalized and aligned. Bands chosen for sequencing are indicated with triangles and numbering on the right side of lanes.
