RNA viruses with complete circular genomes in deep sea. (A) The length and proportion of RNA viruses with circular viral genomes (CVGs). (B) The known and unknown RNA viruses with CVGs. (C) The number of the known RNA viruses with complete CVGs at the family level. (D) The hosts of RNA viruses with circular genomes at the host domain level. (E) The phylogenetic analysis of the classified deep-sea CVG (vOTU-3335) belonging to Retroviridae. The gag protein, protease and reverse transcriptase encoded by deep-sea RNA virus vOTU-3335 and human endogenous retrovirus of Retroviridae were included in the phylogenetic analysis. The numbers on the branches represent the percentage of confidence in the bootstrap test (500 replicates).
