RNA viruses provide unique insights into the patterns and processes of evolutionary change
in real time. The study of viral evolution is especially topical given the growing awareness …

Viruses and mobile genetic elements are molecular parasites or symbionts that coevolve
with nearly all forms of cellular life. The route of virus replication and protein expression is …

Increasing data indicate that insects serve as major reservoirs and vectors of viruses, which
account for the continuously increasing ecological burden and infectious disease outbreaks …

The evolutionary origins of arboviruses are unknown because their typical dual host tropism
is paraphyletic within viral families. Here we studied one of the most diversified and …

Viruses modulate ecosystems by directly altering host metabolisms through auxiliary
metabolic genes. However, viral genomes are not known to encode the core components of …

Abstract Knowledge of the distribution and diversity of RNA viruses is still limited in spite of
their possible environmental and epidemiological impacts because RNA virus-specific …

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 …

RNA viruses are the only known RNA-protein (RNP) entities capable of autonomous
replication (albeit within a permissive host environment). A 33.5 kilobase (kb) nidovirus has …

The nucleocytoplasmic large DNA viruses (NCLDV) of eukaryotes (proposed
order,“Megavirales”) include the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae …

The genome of viruses classified as picornaviruses consists of a single monocistronic
positive strand RNA. The coding capacity of these RNA viruses is rather limited, and thus …
