A universal taxonomy of viruses is essential for a comprehensive view of the virus world and
for communicating the complicated evolutionary relationships among viruses. However …

CRISPR–Cas is a widespread adaptive immune system in bacteria and archaea that
protects against viral infection by targeting specific invading nucleic acid sequences …

Whereas DNA viruses are known to be abundant, diverse, and commonly key ecosystem
players, RNA viruses are insufficiently studied outside disease settings. In this study, we …

Environmental RNA viruses are ubiquitous and diverse, and probably have important
ecological and biogeochemical impacts. Understanding the global diversity of RNA viruses …

High-throughput RNA sequencing offers broad opportunities to explore the Earth RNA
virome. Mining 5,150 diverse metatranscriptomes uncovered> 2.5 million RNA virus contigs …

Public databases contain a planetary collection of nucleic acid sequences, but their
systematic exploration has been inhibited by a lack of efficient methods for searching this …

DNA viruses are increasingly recognized as influencing marine microbes and microbe-
mediated biogeochemical cycling. However, little is known about global marine RNA virus …

Viruses are key members of Earth's microbiomes, shaping microbial community composition
and metabolism. Here, we describe recent advances in'soil viromics', that is, virus-focused …

The increasing prevalence and expanding distribution of tick-borne viruses globally have
raised health concerns, but the full repertoire of the tick virome has not been assessed. We …

Viruses are considered to be the most abundant biological entities on earth. They also
display striking genetic diversity as emphatically demonstrated by the recent advances of …
