Structural Characterization of Two Large Icosahedral DNA Viruses and Their Capsid Assembly Mechanisms [PDF]

, 2020
In the last three decades, many large DNA viruses were discovered and grouped into a loosely defined clade of Nucleocytoplasmic Large DNA Viruses (NCLDVs). NCLDVs infect a wide range of hosts from single cellular protists to large animals.

Génomique comparative des virus géants du clade étendu des asfarviridae

, 2021
Le premier virus géant, Acanthamoeba polyphaga mimivirus, a été découvert en 2003. Ce virus appartient au phylum des Nucleocytoviricota et se caractérisent par une grande taille, d’où leur dénomination de virus «géants».

Elucidating the protein interaction network of one of the largest icosahedral capsids in the virosphere

The EMBO Journal
Giant viruses challenge traditional boundaries of virology with their large particle sizes, complex genomes, and unique replication strategies. Yet, despite its 750 nm diameter and incorporation of dozens of proteins, the mimivirus virion retains an ...

Adaptation strategies of giant viruses to low-temperature marine ecosystems. [PDF]

Microbes in marine ecosystems have evolved their gene content to thrive successfully in the cold. Although this process has been reasonably well studied in bacteria and selected eukaryotes, less is known about the impact of cold environments on the ...

Discovery of giant viruses as past and present infections of zoosporic fungi

Giant viruses of the phylum Nucleocytoviricota have emerged as particularly notable due to their increasingly recognized impacts on eukaryotic genome evolution. Their origins are hypothesized to predate or coincide with the diversification of eukaryotes,

Seasonal dynamics and diversity of Antarctic marine viruses reveal a novel viral seascape

Nature Communications
The Southern Ocean microbial ecosystem, with its pronounced seasonal shifts, is vulnerable to the impacts of climate change. Since viruses are key modulators of microbial abundance, diversity, and evolution, we need a better understanding of the effects ...

A giant virus infecting the amoeboflagellate Naegleria

Nature Communications
Giant viruses (Nucleocytoviricota) are significant lethality agents of various eukaryotic hosts. Although metagenomics indicates their ubiquitous distribution, available giant virus isolates are restricted to a very small number of protist and algal ...
