}} Ligamenvirales is an order of linear viruses that infect archaea of the kingdom Crenarchaeota and have double-stranded DNA genomes.[1] The order was established by David Prangishvili and M. Krupovic in 2012. The name is derived from the Latin {{lang|la|ligamen}}, meaning string or thread. TaxonomyThere are two families in this order – Lipothrixviridae and Rudiviridae. The virons are filamentous with a helical nucleocapsid. At either end are attached either fibers or more complex structures involved in host adhesion. The major coat proteins of both lipothrixviruses and rudiviruses have an unusual four-helix bundle topology.[2] Viruses from the two families share up to ten genes. The genome is non-segmented linear double stranded DNA.
