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 ...

Model of virophage integration into the host virus genome following the Sputnik mechanism.
Cells may be infected by a virus (G), a virus-virophage complex ([Complex]) or a virus carrying a provirophage (Gv). During coinfection by a complex ([Complex]), a proportion λ* of the virus progeny incorporates a virophage into their genomes ...

System outcomes depending on the virophage infection mechanism (log-log plot).
We explored the outcome of the Mavirus and Sputnik models by varying the integration rates (λ) and the inhibition parameter (f), and mapping the dynamical outcomes.

Genome diversity of marine phages recovered from Mediterranean metagenomes: Size matters.
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.

Provirophages in the Bigelowiella genome bear testimony to past encounters with giant viruses
, 2015 Virophages are recently discovered double-stranded DNA virus satellites that prey on giant viruses (nucleocytoplasmic large DNA viruses; NCLDVs), which are themselves parasites of unicellular eukaryotes. This coupled parasitism can result in the indirect

Towards meta-evolution via embodiment in artificial chemistries [PDF]
, 2012 Meta-evolution, the ability to generate novel ways of generating novelty, is one of the major goals of Artificial Life research. Biological systems can be seen to perform open-ended meta-evolution, but unfortunately this has proved very difficult to ...

A giant virus awakens virophage-like PLVs in the green alga Tetraselmis
Giant double-stranded DNA viruses infecting microalgae often interact with polinton-like viruses (PLVs), yet their dynamics within natural hosts remain poorly understood.

Image_2_Guarani Virophage, a New Sputnik-Like Isolate From a Brazilian Lake.TIF
, 2019 Virophages are critical regulators of viral population dynamics and potential actors in the stability of the microbial networks. These small biological entities predate the replicative cycle of giant viruses, such as the members of the Mimiviridae family

, 2019 International audienceAcanthamoeba-infecting Mimiviridae are giant viruses with dsDNA genome up to 1.5 Mb. They build viral factories in the host cytoplasm in which the nuclear-like virus-encoded functions take place.
