Fig. 6From: Vast diversity of prokaryotic virus genomes encoding double jelly-roll major capsid proteins uncovered by genomic and metagenomic sequence analysisPhylogenetic tree for the STIV group MCP. Genbank protein IDs are shown after ‘@’ (whenever available), followed by GenBank nucleotide ID and contig length (nt). Sequences of the new contigs from Loki’s Castle sediments are denoted ‘Loki_contig_xxx’. The numbers at the internal branches indicate local likelihood-based support (percentage points). The root was enforced between two major subgroups that include, respectively, sequences of bacterial and archaeal origins. Taxa abbreviations: B, Bacteria; A, Archaea; PV, PVC group; Ni, Nitrospirae; Pr, Proteobacteria; Ta, Thaumarchaeota; Ca, Crenarchaeota; Ea, Euryarchaeota. Contigs selected for genome analysis are colored green or red (Additional file 6); contigs selected for Fig. 6 are marked with red. Previously characterized viruses and proviruses are marked with bold fontBack to article page
