A comparative study of flow cytometry‐sorted communities and shotgun viral metagenomics in a Singapore municipal wastewater treatment plant

iMeta, Volume 1, Issue 3, September 2022., 2022
This study elucidates the practical protocol of applying fluorescence‐activated cell sorting (FACS) and metagenomics on DNA and RNA viromes. This is the first systematic analysis of viral metagenomics in a municipal wastewater treatment plant with the Modified Ludzack–Ettinger (MLE) process.

A Glimpse of Nucleo-Cytoplasmic Large DNA Virus Biodiversity through the Eukaryotic Genomics Window

Viruses, 2017
The nucleocytoplasmic large DNA viruses (NCLDV) are a group of extremely complex double-stranded DNA viruses, which are major parasites of a variety of eukaryotes. Recent studies showed that certain eukaryotes contain fragments of NCLDV DNA integrated in

The Mimivirus L375 Nudix enzyme hydrolyzes the 5' mRNA cap.

PLoS ONE, 2021
The giant Mimivirus is a member of the nucleocytoplasmic large DNA viruses (NCLDV), a group of diverse viruses that contain double-stranded DNA (dsDNA) genomes that replicate primarily in eukaryotic hosts.

Adaptive evolution of viruses infecting marine microalgae (haptophytes), from acute infections to stable coexistence

Biological Reviews, Volume 97, Issue 1, Page 179-194, February 2022., 2022
ABSTRACT Collectively known as phytoplankton, photosynthetic microbes form the base of the marine food web, and account for up to half of the primary production on Earth. Haptophytes are key components of this phytoplankton community, playing important roles both as primary producers and as mixotrophs that graze on bacteria and protists.

Viral suppressor of RNA silencing in vascular plants also interferes with the development of the bryophyte Physcomitrella patens

Plant, Cell &Environment, Volume 45, Issue 1, Page 220-235, January 2022., 2022
Abstract Plant viruses are important pathogens able to overcome plant defense mechanisms using their viral suppressors of RNA silencing (VSR). Small RNA pathways of bryophytes and vascular plants have significant similarities, but little is known about how viruses interact with mosses. This study elucidated the responses of Physcomitrella patens to two

A vertically transmitted amalgavirus is present in certain accessions of the bryophyte Physcomitrium patens

The Plant Journal, Volume 108, Issue 6, Page 1786-1797, December 2021., 2021
Summary In the last few years, next‐generation sequencing techniques have started to be used to identify new viruses infecting plants. This has allowed to rapidly increase our knowledge on viruses other than those causing symptoms in economically important crops. Here we used this approach to identify a virus infecting Physcomitrium patens that has the

Phylogenetic evidence for extensive lateral acquisition of cellular genes by Nucleocytoplasmic large DNA viruses

BMC Evolutionary Biology, 2008
Background Nucleo-Cytoplasmic Large DNA viruses (NCLDV), a diverse group that infects a wide range of eukaryotic hosts, exhibit a large heterogeneity in genome size (between 100 kb and 1.2 Mb) but have been suggested to form a monophyletic group on the ...

Phylogenetic and phyletic studies of informational genes in genomes highlight existence of a 4 domain of life including giant viruses. [PDF]

PLoS ONE, 2010
The discovery of Mimivirus, with its very large genome content, made it possible to identify genes common to the three domains of life (Eukarya, Bacteria and Archaea) and to generate controversial phylogenomic trees congruent with that of ribosomal genes,

Virus Genomes from Deep Sea Sediments Expand the Ocean Megavirome and Support Independent Origins of Viral Gigantism

mBio, 2019
The nucleocytoplasmic large DNA viruses (NCLDV) of eukaryotes (proposed order, “Megavirales”) include the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae, Marseilleviridae, and Mimiviridae, as well as still unclassified ...

Dynamic genome evolution and complex virocell metabolism of globally-distributed giant viruses

Nature Communications, 2020
Nucleocytoplasmic large DNA viruses (NCLDV) exhibit a large genomic repertoire and complex evolutionary history. Here, the authors generate 501 metagenome-assembled genomes from diverse environments and show NCLDVs to harbor a wide range of potential ...
