Defensive symbiosis against giant viruses in amoebae. [PDF]
Proc Natl Acad Sci U S A, 2022 Protists are important regulators of microbial communities and key components in food webs with impact on nutrient cycling and ecosystem functioning. In turn, their activity is shaped by diverse intracellular parasites, including bacterial symbionts and viruses. Yet, bacteria–virus interactions within protists are poorly understood.

Annual Review of Microbiology, 1999 ▪ Abstract Paramecium bursaria chlorella virus (PBCV-1) is the prototype of a family of large, icosahedral, plaque-forming, double-stranded–DNA-containing viruses that replicate in certain unicellular, eukaryotic chlorella-like green algae. DNA sequence analysis of its 330, 742-bp genome leads to the prediction that this phycodnavirus has 376 protein-

Marine Ecology Progress Series, 1992 Unusually large virus-hke particles (VLPs) with tails were found in water samples from Norwegian and Danish coastal waters. Size of the VLP heads were 340 to 400 nm and the tails were 2.2 to 2.8 vm long. The VLPs occurred at a maximum concentration of about 104 ml-'. The possible hosts are unknown.

Hidden diversity of soil giant viruses [PDF]
Nature Communications, 2018 Abstract Known giant virus diversity is currently skewed towards viruses isolated from aquatic environments and cultivated in the laboratory. Here, we employ cultivation-independent metagenomics and mini-metagenomics on soils from the Harvard Forest, leading to the discovery of 16 novel giant viruses, chiefly ...

Editorial: Large and Giant DNA Viruses [PDF]
Frontiers in Microbiology, 2019 Since the seminal studies involving bacteriophages, the DNA viruses have fascinated the scientific community. DNA viruses were essential not only for the understanding of viral biological process, but also were a fundamental tool for the discovery and expanding knowledge related to cellular processes, such as transcription, translation, DNA repair ...

Ancestrality and Mosaicism of Giant Viruses Supporting the Definition of the Fourth TRUC of Microbes
Frontiers in Microbiology, 2018 Giant viruses of amoebae were discovered in 2003. Since then, their diversity has greatly expanded. They were suggested to form a fourth branch of life, collectively named ‘TRUC’ (for “Things Resisting Uncompleted Classifications”) alongside Bacteria ...

Quantitative Infection Dynamics of Cafeteria Roenbergensis Virus
Viruses, 2018 The discovery of giant viruses in unicellular eukaryotic hosts has raised new questions on the nature of viral life. Although many steps in the infection cycle of giant viruses have been identified, the quantitative life history traits associated with ...
