| Abstract |
The aim of this study was to compare the composition of two deep-sea viral communities obtained from the RomancheFracture Zone in the Atlantic Ocean (collected at 5200 m depth) and the southwest Mediterranean Sea (from 2400 m depth)using a pyro-sequencing approach. The results are based on 18.7% and 6.9% of the sequences obtained from the AtlanticOcean and the Mediterranean Sea, respectively, with hits to genomes in the non-redundant viral RefSeq database. Theidentifiable richness and relative abundance in both viromes were dominated by archaeal and bacterial viruses accountingfor 92.3% of the relative abundance in the Atlantic Ocean and for 83.6% in the Mediterranean Sea. Despite characteristicdifferences in hydrographic features between the sampling sites in the Atlantic Ocean and the Mediterranean Sea, 440 virusgenomes were found in both viromes. An additional 431 virus genomes were identified in the Atlantic Ocean and 75 virusgenomes were only found in the Mediterranean Sea. The results indicate that the rather contrasting deep-sea environmentsof the Atlantic Ocean and the Mediterranean Sea share a common core set of virus types constituting the majority of bothvirus communities in terms of relative abundance (Atlantic Ocean: 81.4%; Mediterranean Sea: 88.7%). |
