RNA viral contig sequences, DOI:10.6084/m9.figshare.28642382. https://figshare.com/s/1542ab1007882e951162 . The raw sequencing reads from the DNA and RNA viral metagenomes have been deposited to NCBI Short Read Archive (accession number: PRJNA1230403 and PRJNA1230580). The raw metatranscriptomic sequencing data have been deposited to NCBI Short Read Archive (accession number: PRJNA1230164). The raw amplicon sequencing data have also been deposited to NCBI Short Read Archive (accession number: PRJNA1230549). The whole 16S rRNA gene sequences of strains WC36, ZRK34, ZRK36, ZRK30, zrk7, zrk8, zrk18, ZRK35, and ZRK38 have been deposited in the GenBank database with accession numbers OK614042, MT076070, MZ646149, OM892919, OP108612, MW581533, MW647584, MW581537, and OP108622, respectively.
