Data from: Using CRISPRs as a metagenomic tool to identify microbial hosts of a diffuse flow hydrothermal vent viral assemblage

Metagenomic analyses of viruses have revealed widespread diversity in the
viriosphere, but it remains a challenge to identify specific hosts for a
viral assemblage. To address this problem, we analyze the viral metagenome
of a northeast Pacific hydrothermal vent with a comprehensive database of
spacers derived from the CRISPR (Clustered Regularly Interspaced Short
Palindromic Repeat) putative immune system. CRISPR spacer matches to the
marine vent virome suggest that viruses infecting hosts from diverse
taxonomic groups are present in this vent environment. Comparative virome
analyses show that CRISPR spacers from vent isolates and from thermophiles
in general have a higher percentage of matches to the vent virome than to
other marine or terrestrial hot spring viromes. However, a high percentage
of hits to spacers from mesophilic hosts, combined with a moderately high
modeled alpha diversity, suggest that the marine vent virome is comprised
of viruses that have the potential to infect diverse taxonomic groups of
multiple thermal regimes in both the bacterial and archaeal domains.
