Phylogenetic and phyletic studies of informational genes in genomes highlight existence of a 4 domain of life including giant viruses. [PDF]
The discovery of Mimivirus, with its very large genome content, made it possible to identify genes common to the three domains of life (Eukarya, Bacteria and Archaea) and to generate controversial phylogenomic trees congruent with that of ribosomal genes,

The Viral Fraction Metatranscriptomes of Lake Baikal
This article characterises viral fraction metatranscriptomes (smaller than 0.2 µm) from the pelagic zone of oligotrophic Lake Baikal (Russia). The study revealed the dominance of transcripts of DNA viruses: bacteriophages and algal viruses. We identified

Dynamic genome evolution and complex virocell metabolism of globally-distributed giant viruses
Nucleocytoplasmic large DNA viruses (NCLDV) exhibit a large genomic repertoire and complex evolutionary history. Here, the authors generate 501 metagenome-assembled genomes from diverse environments and show NCLDVs to harbor a wide range of potential ...

The Old and the New on Viral Diseases in Sturgeon
Although sturgeon production by aquaculture has increased worldwide, a major factor limiting its expansion are infectious diseases, although few data about viral diseases are available however.

Viral rhodopsins 1 are an unique family of light-gated cation channels
Nucleocytoplasmic Large DNA Viruses (NCLDV) that infect algae encode two distinct families of microbial rhodopsins. Here, the authors characterise two proteins form the viral rhodopsin group 1 OLPVR1 and VirChR1, present the 1.4 Å crystal structure of ...

New Insights into Lymphocystis Disease Virus Genome Diversity
Lymphocystis disease viruses (LCDVs) are viruses that infect bony fish which has been found in different locations across the globe. Four virus species have been classified by the International Committee on Taxonomy of Viruses (ICTV), despite remarkable ...

Hidden evolutionary complexity of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes
Background The Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) constitute an apparently monophyletic group that consists of at least 6 families of viruses infecting a broad variety of eukaryotic hosts.

Discovery of Viral Myosin Genes With Complex Evolutionary History Within Plankton
Nucleocytoplasmic large DNA viruses (NCLDVs) infect diverse eukaryotes and form a group of viruses with capsids encapsulating large genomes. Recent studies are increasingly revealing a spectacular array of functions encoded in their genomes, including ...

Near-atomic structure of a giant virus
Nucleocytoplasmic large DNA viruses are a group of viruses that infect many eukaryotic hosts. Here, the authors provide a 3.5 Å resolution icosahedrally-averaged capsid structure of Paramecium bursaria chlorella virus 1 and show how 1800 minor capsid ...
