Abstract

Members of the family Thaspiviridae have linear dsDNA genomes of 27 to 29 kbp and are the first viruses known to infect mesophilic ammonia-oxidizing archaea of the phylum Thaumarchaeota. The spindle-shaped virions of Nitrosopumilus spindle-shaped virus 1 possess short tails at one pole and measure 64±3 nm in diameter and 112±6 nm in length. This morphology is similar to that of members of the families Fuselloviridae and Halspiviridae. Virus replication is not lytic but leads to growth inhibition of the host. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Thaspiviridae, which is available at ictv.global/report/thaspiviridae.

Keywords: ICTV Report; Thaspiviridae; taxonomy.

Genome maps of Nitrosopumilus spindle-shaped virus 1 isolates NSV1-1 and NSV1-2, and of the haloarchaeal halspivirus His1. Shared ORFs are connected by shaded areas based on sequence identity. Functionally equivalent (but not necessarily homologous) genes are indicated with matching colours. Filled circles indicate terminal inverted repeats. pPolB, protein-primed family B DNA polymerase; MCP, major capsid protein (putative); wHTH, winged helix-turn-helix; GTase, glycosyltransferase; MTase, DNA methyltransferase; PCNA, proliferating cell nuclear antigen.
