|Group:||Group I (dsDNA)|
Ligamenvirales is an order of linear viruses that infect archaea of the kingdom Crenarchaeota and have double-stranded DNA genomes. The order was established by D. Prangishvili and M. Krupovic in 2012.
The name is derived from the Latin ligamen, meaning string or thread.
The virons are filamentous with a helical nucleocapsid. At either end are attached either fibers or more complex structures involved in host adhesion.
The genome is non segmented linear double stranded DNA.
