A Brief History of Giant Viruses’ Studies in Brazilian Biomes

Viruses, 2022
Almost two decades after the isolation of the first amoebal giant viruses, indubitably the discovery of these entities has deeply affected the current scientific knowledge on the virosphere. Much has been uncovered since then: viruses can now acknowledge

Giant Viruses—Big Surprises

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.

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.

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 [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.

Advantages and Limits of Metagenomic Assembly and Binning of a Giant Virus

mSystems, 2020
Giant viruses have large genomes, often within the size range of cellular organisms. This distinguishes them from most other viruses and demands additional effort for the successful recovery of their genomes from environmental sequence data.

Past and present giant viruses diversity explored through permafrost metagenomics

Nature Communications, 2022
Although giant viruses are abundant in aquatic environments, less is known about giant viruses in soil. Here, the authors use permafrost metagenomics to reveal giant virus diversity and heterogeneity, as well as gene transfers between viruses from ...

Giant Virus Infection Signatures Are Modulated by Euphotic Zone Depth Strata and Iron Regimes of the Subantarctic Southern Ocean

mSystems, 2023
Viruses can alter the abundance, evolution, and metabolism of microorganisms in the ocean, playing a key role in water column biogeochemistry and global carbon cycles. Large efforts to measure the contribution of eukaryotic microorganisms (e.g., protists)

Molecular biology of giant viruses' DNA replication machinery [PDF]

, 2013
Viruses are the most widespread and abundant entity on this planet, further constituting the largest part of the genosphere. The majority of these infectious agents are miniature, having been described as being smaller than the smallest bacteria.
