FIGURE 3.

Taxonomic affiliation of viral Operational Taxonomic Units (vOTUs) of South China Sea viromes (SCSV) sorted by distribution and average abundance (A). The potential host domains of viral contigs of SCSV (B). The reference genome of vOTU from the cultivated viruses and single-virus genomics were shown. As in Figure 2, the relative abundance (y axis) is computed for each sample as the number of the transcripts per million reads mapped (TPM). Here, the relative abundance of a vOTU is defined as the average abundance of this vOTU across all samples.
