RT Journal Article SR Electronic(1) A1 Prangishvili, David A1 Krupovic, Mart A1 ICTV Report ConsortiumYR 2018 T1 ICTV Virus Taxonomy Profile: Ampullaviridae JF Journal of General Virology, VO 99 IS 3 SP 288 OP 289 DO https://doi.org/10.1099/jgv.0.001023 PB Microbiology Society, SN 1465-2099, AB The family Ampullaviridae includes viruses with linear dsDNA genomes that replicate in hyperthermophilic archaea from the genus Acidianus. The virions have a unique champagne bottle-shaped morphology and consist of a nucleoprotein filament condensed into a cone-shaped core, which is encased by an envelope, with the base of the ‘bottle’ decorated with a ring of 20 filaments. Genome replication is presumably carried out by the virus-encoded protein-primed family B DNA polymerase. The bottle-shaped morphology is unprecedented among viruses of bacteria and eukaryotes and represents a group of archaea-specific virion morphotypes. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Ampullaviridae, which is available at www.ictv.global/report/ampullaviridae., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/jgv.0.001023
