Virome of Giant Panda-Infesting Ticks Reveals Novel Bunyaviruses and Other Viruses That Are Genetically Close to Those from Giant Pandas

Microbiology Spectrum, 2022
Tick infestations have been reported as one of the factors threatening the health of giant pandas, but studies of viral pathogens carried by ticks feeding on the blood of giant pandas are limited. To assess whether blood-sucking ticks of giant pandas can

Giant Viruses Encode Actin-Related Proteins [PDF]

Molecular Biology and Evolution, 2022
Abstract The emergence of the eukaryotic cytoskeleton is a critical yet puzzling step of eukaryogenesis. Actin and actin-related proteins (ARPs) are ubiquitous components of this cytoskeleton. The gene repertoire of the Last Eukaryotic Common Ancestor (LECA) would have therefore harbored both actin and various ARPs.

Characteristics of virophages and giant viruses

Acta Biochimica Polonica, 2018
Five years after being discovered in 2003, some giant viruses were demonstrated to play a role of the hosts for virophages, their parasites, setting out a novel and yet unknown regulatory mechanism of the giant viruses presence in an aqueous. So far, 20 virophages have been registered and 13 of them have been described as a metagenomic material, which ...

Mriyaviruses: small relatives of giant viruses. [PDF]

mBio
AbstractThe phylumNucleocytoviricotaconsists 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 distinct group of viruses with double-stranded (ds) DNA genomes in the ...

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)

High Transcriptional Activity and Diverse Functional Repertoires of Hundreds of Giant Viruses in a Coastal Marine System

mSystems, 2021
The discovery of giant viruses has transformed our understanding of viral complexity. Although viruses have traditionally been viewed as filterable infectious agents that lack metabolism, giant viruses can reach sizes rivalling cellular lineages and ...
