Viruses and other selfish genetic elements are dominant entities in the biosphere, with
respect to both physical abundance and genetic diversity. Various selfish elements …

Originally, viruses were defined as miniscule infectious agents that passed through filters
that retain even the smallest cells. Subsequently, viruses were considered obligate …

The cross-species transmission of viruses from one host species to another is responsible
for the majority of emerging infections. However, it is unclear whether some virus families …

Drosophila melanogaster is a valuable invertebrate model for viral infection and antiviral
immunity, and is a focus for studies of insect-virus coevolution. Here we use a metagenomic …

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 rapid rates of viral evolution allow us to reconstruct the recent history of viruses in great
detail. This feature, however, also results in rapid erosion of evolutionary signal within viral …

The Polydnaviridae (PDV), including the Bracovirus (BV) and Ichnovirus genera, originated
from the integration of unrelated viruses in the genomes of two parasitoid wasp lineages, in …

Very little is known about the ancient origin of retroviruses, but owing to the discovery of their
ancient endogenous viral counterparts, their early history is beginning to unfold. Here we …

The fall armyworm (FAW), Spodoptera frugiperda, is a native pest species in the Western
hemisphere. Since it was first reported in Africa in 2016, FAW has spread throughout the …

Endogenous viruses form an important proportion of eukaryote genomes and a source of
novel functions. How large DNA viruses integrated into a genome evolve when they confer a …
