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.

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

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.

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 ...

Grazing on Marine Viruses and Its Biogeochemical Implications [PDF]

mBio, 2023
Viruses are the most abundant biological entities in the ocean and show great diversity in terms of size, host specificity, and infection cycle. Lytic viruses induce host cell lysis to release their progeny and thereby redirect nutrients from higher to ...

Revisiting giant virus-host dynamics in brown algae: old stories and new perspectives [PDF]

The EMBO Journal
The recent discovery of widespread giant virus sequences integrated into the genomes of diverse eukaryotes, and in particular marine lineages, has reignited interest in the molecular mechanisms underlying giant virus–host interactions.

Evolutionarily conserved grammar rules viral factories of amoeba-infecting members of the hyperdiverse <i>Nucleocytoviricota</i> phylum. [PDF]

Proc Natl Acad Sci U S A
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. Regardless, it is unclear how these viruses achieve such a level of functional conservation without clear ...
