Evolution and Phylogeny of Large DNA Viruses, Mimiviridae and Phycodnaviridae Including Newly Characterized Heterosigma akashiwo Virus [PDF]
Frontiers in Microbiology, 2016 Nucleocytoplasmic DNA viruses are a large group of viruses that harbor double-stranded DNA genomes with sizes of several hundred kbp, challenging the traditional concept of viruses as small, simple ‘organisms at the edge of life’.

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.

The Phycodnaviridae: The Story of How Tiny Giants Rule the World [PDF]
Current Topics in Microbiology and Immunology, 2009 The family Phycodnaviridae encompasses a diverse and rapidly expanding collection of large icosahedral, dsDNA viruses that infect algae. These lytic and lysogenic viruses have genomes ranging from 160 to 560 kb.

GENETIC EXCHANGES OF INTEINS BETWEENPRASINOVIRUSES(PHYCODNAVIRIDAE) [PDF]
Evolution; International Journal of Organic Evolution, 2013 Phylogenetic diversity in the Phycodnaviridae (double-stranded DNA viruses infecting photosynthetic eukaryotes) is most often studied using their DNA polymerase gene (PolB). This gene and its translated protein product can harbor a selfish genetic element called an "intein" that disrupts the sequence of the host gene without affecting its activity ...

Hybrid sequencing reveals the genome of a Chrysochromulina parva virus and highlight its distinct replication strategy [PDF]
BMC GenomicsChrysochromulina parva (C. parva) is a eukaryotic freshwater haptophyte algae found in lakes and rivers worldwide. It is known to be infected by viruses, yet knowledge of the diversity and activity of these viruses is still very limited.

Covariance of Marine Nucleocytoplasmic Large DNA Viruses with Eukaryotic Plankton Communities in the Sub-Arctic Kongsfjorden Ecosystem: A Metagenomic Analysis of Marine Microbial Ecosystems [PDF]
Microorganisms, 2023 Nucleocytoplasmic large DNA viruses (NCLDVs) infect various marine eukaryotes. However, little is known about NCLDV diversity and their relationships with eukaryotic hosts in marine environments, the elucidation of which will advance the current ...

Chlorovirus : a genus of Phycodnaviridae that infects certain chlorella‐like green algae
Molecular Plant Pathology, 2005 SUMMARY Taxonomy: Chlorella viruses are assigned to the family Phycodnaviridae, genus Chlorovirus , and are divided into three species: Chlorella NC64A viruses, Chlorella Pbi

Phycological Research, 2002 SUMMARY The process by which Ectocarpus fasciculatus virus type 1 (EfasV-1) infects zoospores of its brown algal host was studied by electron microscopy. Upon virus attachment to the target cell, the integral membrane component of the viral capsid fuses with the host plasma membrane, and the 140-nm viral DNA-protein core enters the cytosol. Within 5

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 ...
