unexplored. Here, we mine 975 published rumen metagenomes for viral sequences, create
a global rumen virome database (RVD), and analyze the rumen virome for diversity, virus-
host linkages, and potential roles in affecting rumen functions. Containing 397,180 species-
level viral operational taxonomic units (vOTUs), RVD substantially increases the detection
rate of rumen viruses from metagenomes compared with IMG/VR V3. Most of the classified …
