The Gut Virome Database (GVD)

(A) Pie charts showing the number of bacteriophages, eukaryotic viruses, and archaeal viruses in the GVD (center) and their familial taxonomic composition by the bacteriophages (left) and the eukaryotic viruses (right).

(B) Gene-sharing taxonomic network of the GVD, including viral RefSeq viruses v88. RefSeq viruses are highlighted in red. Every node represents a virus genome, whereas connecting edges identify significant gene-sharing between genomes, which form the basis for their clustering in genus-level taxonomy.

(C) Concentric pie chart showing the number of annotated bacterial host phyla (inner) and family (outer) of the GVD viruses. Host taxonomy follows the GTDB database taxonomic classifications, and putative host information per each viral population is listed in Table S2. See also Figures S1 and S2 and Tables S2, S3, and S6.
