The complete genome sequences of archaeal tailed viruses are currently highly underrepresented in sequence databases. Here, we report the genomic 10 new infecting different haloarchaeal hosts. Among these, only two viral genomes closely related to each other and previously described haloviruses HF1 HF2. approximately 760 kb total shows no matches CRISPR/Cas spacer host genomes. Despite their high divergence, were able identify virion structural assembly genes as well coding for DNA RNA metabolic functions. Interestingly, identified many features that shared with bacteriophages, consistent hypothesis bacterial share common ancestry, a lineage containing viruses, bacteriophages eukaryotic predates division three major domains non-viral life. However, general particular, there still considerable number predicted unknown function.
