Summary of the MEGAN taxonomic assignments of viral reads in the off-Tohoku sedimentary virome libraries. The viral reads were identified by BLASTx similarity search (E-value < 10^-5) against the viral sequence database constructed in this study. The numbers of the sequenced reads in each virome library are shown in parentheses. The “other ssDNA viruses” and “other dsDNA viruses” categories represent unclassified viruses and viral families constituting less than 2% of the total viral reads. The “others” comprises unclassified viruses and other components, single-stranded RNA viruses, retro-transcribing viruses, and virophages.
