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

Analysis of virus genomes from glacial environments reveals novel virus groups with unusual host interactions [PDF]
Frontiers in Microbiology, 2015 Microbial communities in glacial ecosystems are diverse, active, and subjected to strong viral pressures and infection rates. In this study we analyse putative virus genomes assembled from three dsDNA viromes from cryoconite hole ecosystems of Svalbard ...

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 ...

Viral dynamics in a high-rate algal pond reveals a burst of Phycodnaviridae diversity correlated with episodic algal mortality [PDF]
mBioThis study explores virus-host dynamics in a unique environment: an industrial high-rate algal pond (HRAP). A wealth of novel DNA algal viruses are revealed, including members of Nucleocytoviricota “giant viruses” and the enigmatic Preplasmiviricota (e.g.

Complex transcriptional regulations of a hyperparasitic quadripartite system in giant viruses infecting protists [PDF]
Nature CommunicationsHyperparasitism is a common pattern in nature that is not limited to cellular organisms. Giant viruses infecting protists can be hyperparasitized by smaller ones named virophages.

A systematic approach to cancer: evolution beyond selection. [PDF]
Clinical and Translational Medicine, Volume 6, Issue 1, December 2017., 2017 Cancer is typically scrutinized as a pathological process characterized by chromosomal aberrations and clonal expansion subject to stochastic Darwinian selection within adaptive cellular ecosystems.

Genome diversity of marine phages recovered from Mediterranean metagenomes: Size matters. [PDF]
PLoS Genetics, 2017 Marine viruses play a critical role not only in the global geochemical cycles but also in the biology and evolution of their hosts. Despite their importance, viral diversity remains underexplored mostly due to sampling and cultivation challenges.

A New Zamilon-like Virophage Partial Genome Assembled from a Bioreactor Metagenome
Frontiers in Microbiology, 2015 Virophages replicate within viral factories inside the Acanthamoeba cytoplasm, and decrease the infectivity and replication of their associated giant viruses.

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

Polinton-like viruses are abundant in aquatic ecosystems [PDF]
Microbiome, 2021 Background Polintons are large mobile genetic elements found in the genomes of eukaryotic organisms that are considered the ancient ancestors of most eukaryotic dsDNA viruses.
