Paleovirology of the DNA viruses of eukaryotes [PDF]

open access: yesTrends in Microbiology, 2022
Paleovirology is the study of ancient viruses and how they have coevolved with their hosts. An increasingly detailed understanding of the diversity, origins, and evolution of the DNA viruses of eukaryotes has been obtained through the lens of paleovirology in recent years.

Paleovirology: inferring viral evolution from host genome sequence data. [PDF]

open access: yesPhilos Trans R Soc Lond B Biol Sci, 2013
Paleovirology is the study of ancient viruses, typically over prehistoric or geological timescales. There is no physical ‘fossil record’ of viruses; virions persist for short time periods, and rapidly degrade leaving no direct trace of their existence.

Historic and Prehistoric Epidemics: An Overview of Sources Available for the Study of Ancient Pathogens

open access: yesEpidemiologia, 2022
Since life on earth developed, parasitic microbes have thrived. Increases in host numbers, or the conquest of a new species, provide an opportunity for such a pathogen to enjoy, before host defense systems kick in, a similar upsurge in reproduction ...

Paleovirology - ghosts and gifts of viruses past. [PDF]

open access: yesCurr Opin Virol, 2011
The emerging field of paleovirology aims to study the evolutionary age and impact of ancient viruses (paleoviruses) on host biology. Despite a historical emphasis on retroviruses, paleoviral 'fossils' have recently been uncovered from a broad swathe of viruses. These viral imprints have upended long-held notions of the age and mutation rate of viruses.

Ancient viral genomes reveal introduction of human pathogenic viruses into Mexico during the transatlantic slave trade

open access: yeseLife, 2021
After the European colonization of the Americas, there was a dramatic population collapse of the Indigenous inhabitants caused in part by the introduction of new pathogens.

The extraordinary evolutionary history of the reticuloendotheliosis viruses [PDF]

open access: yes, 2013
The reticuloendotheliosis viruses (REVs) comprise several closely related amphotropic retroviruses isolated from birds. These viruses exhibit several highly unusual characteristics that have not so far been adequately explained, including their extremely

Structure of the Receptor Binding Domain of EnvP(b)1, an Endogenous Retroviral Envelope Protein Expressed in Human Tissues

open access: yesmBio, 2020
EnvP(b)1 is an endogenous retroviral envelope gene found in human and other primate genomes. We report EnvP(b)1 sequences in primate genomes consistent with an integration event between 40 and 71 million years ago.

Endogenous viral elements reveal associations between a non-retroviral RNA virus and symbiotic dinoflagellate genomes [PDF]

open access: yes, 2023
Endogenous viral elements (EVEs) offer insight into the evolutionary histories and hosts of contemporary viruses. This study leveraged DNA metagenomics and genomics to detect and infer the host of a non-retroviral dinoflagellate-infecting +ssRNA virus ...

Paleovirology and virally derived immunity

open access: yesTrends in Ecology & Evolution, 2012
Paleovirology, the study of viruses on evolutionary timescales, can exploit information from endogenous viral elements (EVEs), which are the result of heritable horizontal gene transfer (HGT) from viruses to hosts. The availability of genomic data has increased opportunities to study EVEs, and bioinformatics techniques have been crucial in cataloguing ...

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

open access: yes, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...
