Evolutionarily conserved grammar rules viral factories of amoeba-infecting members of the hyperdiverse Nucleocytoviricota phylum [PDF]

Proceedings of the National Academy of Sciences
Despite sharing fewer than 10 core genes, the hyperdiverse Nucleocytoviricota phylum (ranging from poxviruses to giant viruses) universally assembles viral factories (VFs) resembling biomolecular condensates.

Investigations into the Diversity and Distribution of tRNA and Phylogenetics of Translation Factors in Amoebozoa-Infecting Nucleocytoviricota

Viruses
Translation is a sine qua non process for life as we know it. Translation factors (TFs) and tRNAs are rare among viruses but are commonly found in giant viruses of the class Megaviricetes.

A phylogenomic framework for charting the diversity and evolution of giant viruses.

PLoS Biology, 2021
Large DNA viruses of the phylum Nucleocytoviricota have recently emerged as important members of ecosystems around the globe that challenge traditional views of viral complexity.

Kratosvirus quantuckense: the history and novelty of an algal bloom disrupting virus and a model for giant virus research [PDF]

Frontiers in Microbiology, 2023
Since the discovery of the first “giant virus,” particular attention has been paid toward isolating and culturing these large DNA viruses through Acanthamoeba spp. bait systems.

Evidence for the acquisition of a proteorhodopsin-like rhodopsin by a chrysophyte-infecting giant virus [PDF]

Journal of Virology
Chrysophytes are nanoflagellate protists widespread in aquatic ecosystems with diverse trophic roles as primary producers and bacterivores. Molecular evidence suggests that chrysophytes are commonly infected by giant viruses, but isolates of such virus ...

Epigenome analysis of an algae-infecting giant virus reveals a unique methylation motif catalogue. [PDF]

PLoS ONE
DNA methylation can epigenetically alter gene expression and serve as a mechanism for genomic stabilization. Advancements in long-read sequencing technology have allowed for increased exploration into the methylation profiles of various organisms ...

Assessing the biogeography of marine giant viruses in four oceanic transects

ISME Communications, 2023
Viruses of the phylum Nucleocytoviricota are ubiquitous in ocean waters and play important roles in shaping the dynamics of marine ecosystems. In this study, we leveraged the bioGEOTRACES metagenomic dataset collected across the Atlantic and Pacific ...

The double histone fold: Structure, functional implications across the tree of life and relevance to protein design [PDF]

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The histone fold is one of the most ancient and versatile structural motifs in protein biology, best known for its role in chromatin organization. A remarkable variation of this motif is the double histone fold (DHF), in which two histone folds are encoded within a single polypeptide chain and assemble intramolecularly into a histone‐like ...

Nucleocytoviricota viral factories are transient organelles made by liquid-liquid phase separation

Phase separation is a widespread mechanism in viral processes, mediating replication, host manipulation and virion morphogenesis. The phylum Nucleocytoviricota encompasses diverse and ubiquitous viruses, including Poxviridae, the climate-modulating
