Figure 3. Dendrograms comparing the level of similarity between metagenomic libraries constructed from bleached tissue (B), from tissue adjacent to bleached tissue (A) and healthy tissue (H) using a matrix containing ORFs that could be matched to COGs with E-value cut-offs of 10.

⁻⁵ (a), 10 ⁻¹⁰ (b) and 10 ⁻²⁰ (b).
