Viral contigs from Trout Bog Lake (TBL) were clustered with genomes from the NCBI Viral RefSeq database [82] as well as predicted GSB viruses from IMG/VR [5] and Lake Mendota viral contigs, based on pairwise gene comparison. GSB viral contigs were dereplicated prior to clustering, so that only one copy of each genome was included in the network. Individual viral contigs are colored according to their origin (gray for sequences not from Trout Bog Lake, blue for Trout Bog Lake contigs not associated with GSB, and red for Trout Bog Lake contigs associated with GSB). The GSB-associated viral contigs detected in the GSB-targeted metagenomes are highlighted with a square shape. Network edges represent shared gene content between viral contigs. GSB viral contigs clustered into four groups (VC-1, -2, -3, and -4). VC-1 contains the three CV-1-33 variants; VC-3 and VC-4 contain CV-1-51 and CV-1-4.2, respectively, plus a previously sequenced TBL metagenome viral contig from 2008. Pairwise genome alignments are represented next to each cluster. Genome alignments were generated using blastn, with green representing 100% nucleotide alignment. Gene content is color-coded, and dashed lines show regions where the host genome was found. All GSB viral contigs from targeted metagenomes (red squares) are labeled with their host (either “A” for GSB-A or “B” for GSB-B).
