An Uncultivated Virus Infecting a Nanoarchaeal Parasite in the Hot Springs of Yellowstone National Park.

ABSTRACT: The Nanoarchaeota are small cells with reduced genomes that are found attached to and dependent on a second archaeal cell for their growth and replication. Initially found in marine hydrothermal environments and subsequently in terrestrial geothermal hot springs, the Nanoarchaeota species that have been described are obligate ectobionts, each with a different host species. However, no viruses had been described that infect the Nanoarchaeota. Here, we identify a virus infecting Nanoarchaeota by the use of a combination of viral metagenomic and bioinformatic approaches. This virus, tentatively named Nanoarchaeota Virus 1 (NAV1), consists of a 35.6-kb circular DNA genome coding for 52 proteins. We further demonstrate that this virus is broadly distributed among Yellowstone National Park hot s
