The Double-Stranded DNA Virosphere as a Modular Hierarchical Network of Gene Sharing [PDF]
Virus genomes are prone to extensive gene loss, gain, and exchange and share no universal genes. Therefore, in a broad-scale study of virus evolution, gene and genome network analyses can complement traditional phylogenetics.

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

Megavirales Composing a Fourth Domain of Life: Mimiviridae and Marseilleviridae
The 2003 discovery of Acanthamoeba polyphaga Mimivirus led to several breakthroughs and subsequent discussions related to the evolution, origin and definition of viruses and dramatically boosted scientific interest in giant viruses. Mimivirus was the largest virus with respect to particle size and genome length, and its analysis blurred the paradigms ...

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution.
Genome gigantism occurs so far in Phycodnaviridae and Mimiviridae (order Megavirales). Origin and evolution of these Giant Viruses (GVs) remain open questions.

Evolution of double-stranded DNA viruses of eukaryotes: from bacteriophages to transposons to giant viruses. [PDF]
International audienceDiverse eukaryotes including animals and protists are hosts to a broad variety of viruses with double-stranded (ds) DNA genomes, from the largest known viruses, such as pandoraviruses and mimiviruses, to tiny polyomaviruses.
