Comparative Genomics and Environmental Distribution of Large dsDNA Viruses in the Family Asfarviridae

Frontiers in Microbiology, 2021
The family Asfarviridae is a group of nucleo-cytoplasmic large DNA viruses (NCLDVs) of which African swine fever virus (ASFV) is well-characterized. Recently the discovery of several Asfarviridae members other than ASFV has suggested that this family ...

Coral Bleaching Phenotypes Associated With Differential Abundances of Nucleocytoplasmic Large DNA Viruses

Frontiers in Marine Science, 2020
Eukaryotic viruses and bacteriophage have been implicated in disease and bleaching in corals, but the compositional and functional diversity of these viruses in healthy and compromised hosts remains underexplored. To investigate whether viral assemblages

Viral rhodopsins 1 are an unique family of light-gated cation channels

Nature Communications, 2020
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 ...

RNA Sequencing of Medusavirus Suggests Remodeling of the Host Nuclear Environment at an Early Infection Stage

Microbiology Spectrum, 2021
Viruses of the phylum Nucleocytoviricota, or nucleo-cytoplasmic large DNA viruses (NCLDVs), undergo a cytoplasmic or nucleo-cytoplasmic cycle, the latter of which involves both nuclear and cytoplasmic compartments to proceed viral replication ...

The genome of the brown alga Ectocarpus siliculosus contains a series of viral DNA pieces, suggesting an ancient association with large dsDNA viruses

BMC Evolutionary Biology, 2008
Background Ectocarpus siliculosus virus-1 (EsV-1) is a lysogenic dsDNA virus belonging to the super family of nucleocytoplasmic large DNA viruses (NCLDV) that infect Ectocarpus siliculosus, a marine filamentous brown alga. Previous studies indicated that

Discovery of Viral Myosin Genes With Complex Evolutionary History Within Plankton

Frontiers in Microbiology, 2021
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 ...

Phylogeny of the Varidnaviria Morphogenesis Module: Congruence and Incongruence With the Tree of Life and Viral Taxonomy

Frontiers in Microbiology, 2021
Double-stranded DNA viruses of the realm Varidnaviria (formerly PRD1-adenovirus lineage) are characterized by homologous major capsid proteins (MCPs) containing one (kingdom: Helvetiavirae) or two β-barrel domains (kingdom: Bamfordvirae) known as the ...

Hi‐C Links Reveal Viral Activity and Infection Within the Free‐Living Microbial Community of a Secondary Chlorophyll Maximum in the Eastern Tropical North Pacific

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Hi‐C sequencing was used to link viral sequences with microbial metagenome assembled genomes in the largely uncultivated waters of an oxygen‐deficient zone's secondary chlorophyll maximum within the Eastern Tropical North Pacific Ocean. ABSTRACT Oxygen‐deficient zones (ODZs) influence global nitrogen cycling as key sites for the removal of bioavailable
