The Prevalence of STIV c92-Like Proteins in Acidic Thermal Environments
A maximum likelihood phylogenetic tree of c92-like proteins from YNP metagenomes illustrating three major families. SRV: Stygiolobus rod-shaped virus (outgroup); SIRV1: Sulfolobus islandicus rod-shaped virus 1; SIRV1 XX: SIRV1 variant XX; SIRV2: Sulfolobus islandicus rod-shaped virus 2; STIV: Sulfolobus turreted icosahedral virus; NL: Nymph Lake metagenomes; CH: Crater Hills metagenomes; sample names indicate cellular (c) or viral (v) metagenomes and the year followed by the month of sample collection; short contigs indicated by *. The numbers at the branches represent clade probabilities, and the scale bar represents the average number of substitutions per site.
