, 2022 Abstract This study approaches a high rate algal pond (HRAP) culture by metagenomic sequencing of the viral DNA fraction, this includes the so-called giant virus fraction (phylum Nucleocytoviricota ), with the goal of revealing viruses coexisting within an intensified algal culture.

Metagenomic Analysis of Virus Diversity and Relative Abundance in a Eutrophic Freshwater Harbour
Viruses, 2019 Aquatic viruses have been extensively studied over the past decade, yet fundamental aspects of freshwater virus communities remain poorly described. Our goal was to characterize virus communities captured in the >0.22 µm size-fraction seasonally ...

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution.
Frontiers in Microbiology, 2015 Genome gigantism occurs so far in Phycodnaviridae and Mimiviridae (order Megavirales). Origin and evolution of these Giant Viruses (GVs) remain open questions.

Novel virophages discovered in a freshwater lake in China
Frontiers in Microbiology, 2016 Virophages are small double-stranded DNA viruses that are parasites of giant DNA viruses that infect unicellular eukaryotes. Here we identify a novel group of virophages, named Dishui Lake virophages (DSLVs) that were discovered in Dishui Lake (DSL): an ...

New Isolates of Betachloroviruses Shed Light on the Diversity and Biological Complexity of an Unexplored Group of Giant Algal Viruses [PDF]
VirusesThe majority of giant algal viruses belong to the family Phycodnaviridae, class Algavirales, phylum Nucleocytoviricota. Among them, the genus Chlorovirus is the most studied, with three recognized groups based on genomics and host range, although many ...

Elucidating Viral Communities During a Phytoplankton Bloom on the West Antarctic Peninsula [PDF]
Frontiers in Microbiology, 2019 In Antarctic coastal waters where nutrient limitations are low, viruses are expected to play a major role in the regulation of bloom events. Despite this, research in viral identification and dynamics is scarce, with limited information available for the

Remarkable sequence similarity between the dinoflagellate-infecting marine girus and the terrestrial pathogen African swine fever virus [PDF]
Virology Journal, 2009 Heterocapsa circularisquama DNA virus (HcDNAV; previously designated as HcV) is a giant virus (girus) with a ~356-kbp double-stranded DNA (dsDNA) genome. HcDNAV lytically infects the bivalve-killing marine dinoflagellate H. circularisquama, and currently
