Lineage-specific expansions of polinton-like viruses in photosynthetic cryptophytes [PDF]
MicrobiomeBackground Polinton-like viruses (PLVs) are diverse eukaryotic DNA viral elements (14–40 kb) that often undergo significant expansion within protist genomes through repeated insertion events. Emerging evidence indicates they function as antiviral defense

The Expanding Family of Virophages [PDF]
Viruses, 2016 Virophages replicate with giant viruses in the same eukaryotic cells. They are a major component of the specific mobilome of mimiviruses. Since their discovery in 2008, five other representatives have been isolated, 18 new genomes have been described ...

Virophages and retrotransposons colonize the genomes of a heterotrophic flagellate
eLife, 2020 Virophages can parasitize giant DNA viruses and may provide adaptive anti-giant-virus defense in unicellular eukaryotes. Under laboratory conditions, the virophage mavirus integrates into the nuclear genome of the marine flagellate Cafeteria burkhardae ...

Virophages, polintons, and transpovirons: a complex evolutionary network of diverse selfish genetic elements with different reproduction strategies [PDF]
Virology Journal, 2013 BackgroundRecent advances of genomics and metagenomics reveal remarkable diversity of viruses and other selfish genetic elements. In particular, giant viruses have been shown to possess their own mobilomes that include virophages, small viruses that ...

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.

Viral dynamics in a high-rate algal pond reveals a burst of Phycodnaviridae diversity correlated with episodic algal mortality [PDF]
mBioThis study explores virus-host dynamics in a unique environment: an industrial high-rate algal pond (HRAP). A wealth of novel DNA algal viruses are revealed, including members of Nucleocytoviricota “giant viruses” and the enigmatic Preplasmiviricota (e.g.
