Archaeal Viruses

∞ generated and posted on 2017.05.01 ∞

Archaeal viruses are the semi-autonomous, acellular parasites of domain Archaea.

Archaeal viruses are notable especially for their diverse and unusual virion structures, only a few of which are seen as well among bacterial viruses or viruses of eukaryotes. Given the small number of so-far described isolates, it is unlikely that any but a fraction of archaeal virus diversity is currently known.

Archaeal virus genomes are double-stranded DNA unless otherwise indicated, and all listed types are DNA rather than RNA viruses.

Another of my efforts towards generating an archaeal viruses table can be found here and includes the source of isolation of many of these viruses. In addition, much of the pre-2013 archaeal virus literature can be found in supplemental material as reached here.
