Simultaneous Giant Virus and Virophage Quantification Using Droplet Digital PCR [PDF]
Viruses, 2022 Viruses are an abundant component of aquatic systems, but their detection and quantification remain a challenge. Virophages co-replicate with giant viruses in the shared host cell, and can inhibit the production of new giant virus particles, thereby ...

Giant virus vs amoeba: fight for supremacy [PDF]
Virology Journal, 2019 Since the discovery of mimivirus, numerous giant viruses associated with free-living amoebae have been described. The genome of giant viruses can be more than 2.5 megabases, and virus particles can exceed the size of many bacteria.

Genome-resolved year-round dynamics reveal a broad range of giant virus microdiversity [PDF]
mSystemsGiant viruses are crucial for marine ecosystem dynamics because they regulate microeukaryotic community structure, accelerate carbon and nutrient cycles, and drive the evolution of their hosts through co-evolutionary processes.

Diverse Trajectories Drive the Expression of a Giant Virus in the Oomycete Plant Pathogen Phytophthora parasitica [PDF]
Frontiers in Microbiology, 2021 Giant viruses of amoebas, recently classified in the class Megaviricetes, are a group of viruses that can infect major eukaryotic lineages. We previously identified a set of giant virus sequences in the genome of Phytophthora parasitica, an oomycete and ...

Near-atomic architecture of Singapore grouper iridovirus and implications for giant virus assembly. [PDF]
Nat Commun, 2023 Singapore grouper iridovirus (SGIV), one of the nucleocytoviricota viruses (NCVs), is a highly pathogenic iridovirid. SGIV infection results in massive economic losses to the aquaculture industry and significantly threatens global biodiversity. In recent

Giant Virus Infection Signatures Are Modulated by Euphotic Zone Depth Strata and Iron Regimes of the Subantarctic Southern Ocean. [PDF]
mSystems, 2023 The biology and ecology of marine microbial eukaryotes is known to be constrained by oceanic conditions. In contrast, how viruses that infect this important group of organisms respond to environmental change is less well known, despite viruses being ...

Near-atomic, non-icosahedrally averaged structure of giant virus Paramecium bursaria chlorella virus 1. [PDF]
Nat Commun, 2022 Giant viruses are a large group of viruses that infect many eukaryotes. Although components that do not obey the overall icosahedral symmetry of their capsids have been observed and found to play critical roles in the viral life cycles, identities and ...

Cryptic infection of a giant virus in a unicellular green alga. [PDF]
ScienceLatency is a common strategy in a wide range of viral lineages, but its prevalence in giant viruses remains unknown. Here we describe a 617 kbp integrated giant viral element in the model green alga Chlamydomonas reinhardtii.
