a Workflow for identification, taxonomic assignment, and lifestyle prediction of viruses. Phylogenomic trees of predicted (b) archaeal and (c) bacterial hosts based on concatenated alignments of single-copy marker genes predicted by GTDB-Tk. Scale bars indicate the average number of substitutions per site. The orange triangle shows the number of viruses predicted to infect hosts in each clade, and the blue circle shows the number of microbial genomes in each clade with predicted viruses. Detailed statistics for taxonomy, lifestyles, and host-virus linkages are provided in Supplementary TablesĀ 6 and 7.
