FIGURE 4.
Heatmap of Operational Taxonomic Units (OTU) identified in molluskan samples. DNA for the 16S amplicon sequencing was extracted from either G = gill; D = digestive gland; M = mantle; GN = gonads; and V = various organs (for DNA extracted from formalin-fixed paraffin-embedded tissues). Numbers indicate the OTU sample identification (ID) shown on the phylogenetic trees in this figure.
