A deep dive into giant viruses [PDF]

npj Viruses
Giant viruses are a complex and diverse group infecting organisms from unicellular eukaryotes to animals. From the characterization of novel viruses to the development of advanced bioinformatic tools for taxonomy and classification, these collection of ...

Giant Viruses—Big Surprises [PDF]

Viruses, 2019
Viruses are the most prevalent infectious agents, populating almost every ecosystem on earth. Most viruses carry only a handful of genes supporting their replication and the production of capsids.

Mriyaviruses: small relatives of giant viruses. [PDF]

mBio
Abstract The phylum Nucleocytoviricota consists of large and giant viruses that range in genome size from about 100 kilobases (kb) to more than 2.5 megabases. Here, using metagenome mining followed by extensive phylogenomic analysis and protein structure comparison, we delineate a ...

20 years of research on giant viruses. [PDF]

Npj Viruses
Abstract Some twenty years ago, the discovery of the first giant virus, Acanthamoeba polyphaga mimivirus (now mimivirus bradfordmassiliense species), paved the way for the discovery of more than 10 new families of protist-infecting DNA viruses with unexpected diversity in virion shape and size, gene content, genome topology and mode of ...

Giant endogenous viral elements in the genome of the model protist Euglena gracilis reveal past interactions with giant viruses [PDF]

Journal of Virology
Genomes of giant viruses (phylum Nucleocytoviricota) have increasingly been found integrated into the genomes of diverse eukaryotes. Here, we report eight giant endogenous viral elements (GEVEs) in the genome of the microalgae Euglena gracilis. The GEVEs

Giant viruses of amoebas: an update [PDF]

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.

Mirusviruses link herpesviruses to giant viruses. [PDF]

Nature, 2023
Abstract DNA viruses have a major influence on the ecology and evolution of cellular organisms 1–4 , but their overall diversity and evolutionary trajectories remain elusive 5 .

Multiple evolutionary origins of giant viruses [version 1; referees: 4 approved] [PDF]

F1000Research, 2018
The nucleocytoplasmic large DNA viruses (NCLDVs) are a monophyletic group of diverse eukaryotic viruses that reproduce primarily in the cytoplasm of the infected cells and include the largest viruses currently known: the giant mimiviruses, pandoraviruses,

Metabolic arsenal of giant viruses: Host hijack or self-use? [PDF]

eLife, 2022
Viruses generally are defined as lacking the fundamental properties of living organisms in that they do not harbor an energy metabolism system or protein synthesis machinery.

Molecular architecture of giant viruses infecting microbial eukaryotes (protists) [PDF]

BioTechnologia
In this review, I describe recent findings on the molecular architecture and genomic characterization of giant viruses that infect microbial eukaryotes (protists) across diverse ecosystems and ecological niches.
