BEREN: a bioinformatic tool for recovering giant viruses, polinton-like viruses, and virophages in metagenomic data. [PDF]

Bioinform Adv
Viruses in the kingdom Bamfordvirae, specifically giant viruses (NCLDVs) in the phylum Nucleocytoviricota and smaller members in the Preplasmiviricota phylum, are widespread and important groups of viruses that infect eukaryotes.

Zamilon, a novel virophage with Mimiviridae host specificity. [PDF]

PLoS ONE, 2014
Virophages, which are potentially important ecological regulators, have been discovered in association with members of the order Megavirales. Sputnik virophages target the Mimiviridae, Mavirus was identified with the Cafeteria roenbergensis virus, and ...

Viva lavidaviruses! Five features of virophages that parasitize giant DNA viruses. [PDF]

PLoS Pathogens, 2019
Viruses are obligate intracellular parasites and thus cannot replicate outside a living cell. Whereas a susceptible and permissive host cell is sufficient for most viruses to produce infectious progeny, some viruses such as satellite viruses require two ...

Conserved tripartite tail proteins mediate virophage-host interactions through Synechococcus lipopolysaccharide binding [PDF]

Journal of Virology
Virophages are small double-stranded DNA viruses that parasitize giant viruses and play crucial roles in microbial ecosystem dynamics. In this study, we investigate three evolutionarily conserved tail proteins in Dishui Lake Virophage 2 (DSLV2) that ...

Amoebae, Giant Viruses, and Virophages Make Up a Complex, Multilayered Threesome

Frontiers in Cellular and Infection Microbiology, 2018
Viral infection had not been observed for amoebae, until the Acanthamoeba polyphaga mimivirus (APMV) was discovered in 2003. APMV belongs to the nucleocytoplasmatic large DNA virus (NCLDV) family and infects not only A.

Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]

Ecology and Evolution, 2013
Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

Ecogenomics of virophages and their giant virus hosts assessed through time series metagenomics

Nature Communications, 2017
Virophages are recently-identified small viruses that infect larger viruses, yet their diversity and ecological roles are poorly understood. Here, Roux and colleagues present time series metagenomics data revealing new virophage genera and their putative

Large-scale invasion of unicellular eukaryotic genomes by integrating DNA viruses. [PDF]

Proc Natl Acad Sci U S A, 2023
Eukaryotic genomes contain a variety of endogenous viral elements (EVEs), which are mostly derived from RNA and ssDNA viruses that are no longer functional and are considered to be “genomic fossils.” Genomic surveys of EVEs, however, are strongly biased ...

The Discovery of a New Mimivirus Isolate in Association with Virophage-Transpoviron Elements in Brazil Highlights the Main Genomic and Evolutionary Features of This Tripartite System [PDF]

Viruses, 2022
Mimiviruses are giant viruses of amoeba that can be found in association with virophages. These satellite-like viruses are dependent on the mimivirus viral factory to replicate.

Seasonal dynamics and diversity of Antarctic marine viruses reveal a novel viral seascape. [PDF]

Nat Commun
The Southern Ocean microbial ecosystem, with its pronounced seasonal shifts, is vulnerable to the impacts of climate change. Since viruses are key modulators of microbial abundance, diversity, and evolution, we need a better understanding of the effects ...
