Fig. 6

Predicted virus-host linkages among candidate sulfate-reducing strains. Linkages are displayed based on wetland (P7 in green and P8 in purple). Each host (circles) is identified by taxonomic affiliation and genome name, while viruses (other shapes) are only shown based on taxonomy. Increasing abundances are indicated by darker color shades, with abundances represented by average RPKM value across samples from each wetland. For sulfate reducers, the dsrD-containing contig was prioritized in RPKM calculations, and only genomes missing dsrD had their abundances represented by reductive dsrA-containing contigs (Additional file 10: Table S5). The four prediction methods are represented by the different color-coded lines
