An Update on Eukaryotic Viruses Revived from Ancient Permafrost

Viruses, 2023
One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred to as permafrost. Due to climate warming, irreversibly thawing permafrost is releasing organic matter frozen for up to a million years, most of which decomposes ...

A Brazilian Marseillevirus Is the Founding Member of a Lineage in Family Marseilleviridae

Viruses, 2016
In 2003, Acanthamoeba polyphaga mimivirus (APMV) was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae.

The giant mimivirus 1.2 Mb genome is elegantly organized into a 30-nm diameter helical protein shield

eLife, 2022
Mimivirus is the prototype of the Mimiviridae family of giant dsDNA viruses. Little is known about the organization of the 1.2 Mb genome inside the membrane-limited nucleoid filling the ~0.5 µm icosahedral capsids. Cryo-electron microscopy, cryo-electron

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 ...

Quantitative conversion of biomass in giant DNA virus infection [PDF]

Scientific Reports, 2021
AbstractBioconversion of organic materials is the foundation of many applications in chemical engineering, microbiology and biochemistry. Herein, we introduce a new methodology to quantitatively determine conversion of biomass in viral infections while simultaneously imaging morphological changes of the host cell.
