Evolutionary History of Immunomodulatory Genes of Giant Viruses
Nucleocytoplasmic large DNA viruses (NCLDVs) have genome sizes that range from around 100 kilobases (kb) to up to 2.5 megabases, and virion sizes that can reach up to 1.5 μm. Their large size in both of these contexts is atypical and defies the traditional view that viruses are streamlined, …

Metagenomic approaches for examining the diversity of large DNA viruses in the biosphere
The discovery of large DNA viruses has challenged the traditional perception of viral complexity due to their enormous genome size and physical dimensions. Previously, viruses were considered small, filterable agents until the discovery of large DNA viruses. Among large DNA viruses, the phylum …

Comparative and Evolutionary genomics of Nucleocytoviricota
Viruses have been historically identified by their smaller sizes and simple genomic features compared to cellular life forms. Advances in virus cultivation and metagenomic analysis in recent years have shown that giant viruses, classified within the phylum Nucleocytoviricota, possess remarkably …

Origin of viruses revealed by the genomic study of protein domain structures
The discovery of giant viruses with complex proteomes, remnants of translation machinery and virus-specific parasites have raised important questions about their origin. Evidence advocates for their inclusion into global phylogenomic studies and their consideration as a distinct and ancient form of …

Investigating virus-host interactions in a changing Arctic Ocean
… well understood. The AO is also a hotspot for giant virus diversity, and M. polaris is susceptible to infection by giant viruses known as Micromonas polaris viruses (MpoVs). Previous research has characterised MpoV infection dynamics and the potential for these to be affected by warming, yet …

Microbial biodiversity in the southern Indian Ocean and Southern Ocean
… ranges from the numerically dominant viruses to the diverse climate-change regulating phytoplankton. Recent advances in next generation sequencing are starting to reveal the true diversity and biological complexity of this previously invisible component of Earth's hydrosphere. An …
