Family: Rudiviridae

Rudiviridae is a family of viruses[1] with linear double stranded DNA genomes that infect archaea. The viruses of this family are highly thermostable and can act as a template for site-selective and spatially controlled chemical modification. Furthermore, the two strands of the DNA are covalently linked at both ends of the genomes, which have long inverted terminal repeats.[2] These inverted repeats are an adaptation to stabilize the genome in these extreme environments.[3]


The following genera are assigned to the family:[1]
