Genomic analysis of viral sulfate reduction genes. a Genome map of seven viral scaffolds containing assimilatory sulfate reduction genes. Genes related to replication, recombination, and repair are shown in light purple; genes related to metabolism are shown in dark blue; genes related to cellular processes and signaling are shown in green; viral hallmark genes are in orange; and assimilatory sulfur reduction genes (COG0175) are in dark purple and unknown genes are in grey. Detailed function descriptions of the seven viral scaffolds are listed in Additional file 1: Table S9. b Maximum-likelihood phylogenetic tree with assimilatory sulfate reduction genes from mine tailings viral genomes (indicated by stars) compared to genes found in bacterial reference sequences (the “Methods” section). The scale bar represents 1 amino acid substitution per site. c Total relative abundance of COG0175 and genomes containing COG0175 in each tailings layer viral genome
