Diverse Trajectories Drive the Expression of a Giant Virus in the Oomycete Plant Pathogen Phytophthora parasitica

Frontiers in Microbiology, 2021
Giant viruses of amoebas, recently classified in the class Megaviricetes, are a group of viruses that can infect major eukaryotic lineages. We previously identified a set of giant virus sequences in the genome of Phytophthora parasitica, an oomycete and ...

Virophages and Their Interactions with Giant Viruses and Host Cells

Proteomes, 2018
Virophages are small dsDNA viruses that were first isolated in association with some giant viruses (GVs), and then found in metagenomics samples. They encode about 20–34 proteins.

The kinetoplastid-infecting Bodo saltans virus (BsV), a window into the most abundant giant viruses in the sea

eLife, 2018
Giant viruses are ecologically important players in aquatic ecosystems that have challenged concepts of what constitutes a virus. Herein, we present the giant Bodo saltans virus (BsV), the first characterized representative of the most abundant group of ...

Genome-resolved year-round dynamics reveal a broad range of giant virus microdiversity

mSystems
Giant viruses are crucial for marine ecosystem dynamics because they regulate microeukaryotic community structure, accelerate carbon and nutrient cycles, and drive the evolution of their hosts through co-evolutionary processes.

Host Range and Coding Potential of Eukaryotic Giant Viruses

Viruses, 2020
Giant viruses are a group of eukaryotic double-stranded DNA viruses with large virion and genome size that challenged the traditional view of virus. Newly isolated strains and sequenced genomes in the last two decades have substantially advanced our ...

Giant viruses of amoebas: an update

Frontiers in Microbiology, 2016
During the 12 past years, five new or putative virus families encompassing several members, namely Mimiviridae, Marseilleviridae, pandoraviruses, faustoviruses, and virophages were described.

Correlative light electron microscopy of giant viruses with the SECOM system

New Microbes and New Infections, 2018
Bright-field transmission electron microscopy (TEM), TEM-negative staining technique, resin-embedding and ultramicrotomy, scanning TEM, scanning electron microscopy, atomic force microscopy and cryoelectron microscopy are imaging techniques used for ...

Tailed giant Tupanvirus possesses the most complete translational apparatus of the known virosphere

Nature Communications, 2018
Giant viruses are the largest viruses of the known virosphere and their genetic analysis can provide insights into virus evolution. Here, the authors discover Tupanvirus, a unique giant virus that has an unusually long tail and contains the largest ...

Influenza A(H1N1)pdm09 Virus Infection in Giant Pandas, China

Emerging Infectious Diseases, 2014
We confirmed infection with influenza A(H1N1)pdm09 in giant pandas in China during 2009 by using virus isolation and serologic analysis methods. This finding extends the host range of influenza viruses and indicates a need for increased surveillance for ...

A protein of the metallo-hydrolase/oxidoreductase superfamily with both beta-lactamase and ribonuclease activity is linked with translation in giant viruses

Scientific Reports, 2020
Proteins with a metallo-beta-lactamase (MBL) fold have been largely studied in bacteria in the framework of resistance to beta-lactams, but their spectrum of activities is broader.
