Current capsid assembly models of icosahedral nucleocytoviricota viruses [PDF]

, 2020
Nucleocytoviricota viruses (NCVs) belong to a newly established phylum originally grouped as Nucleocytoplasmic large DNA viruses. NCVs are unique because of their large and complicated genomes that contain cellular genes with homologs from all kingdoms of life, raising intensive debates on their evolutional origins.

A rapid genome‐wide analysis of isolated giant viruses using MinION sequencing

Environmental Microbiology, Volume 25, Issue 11, Page 2621-2635, November 2023., 2023
We evaluated performance of MinION sequencing for giant virus genomics. Re‐sequencing of a prototype marseillevirus by MinION alone provided high‐quality genomes. As a proof of concept, we sequenced genomes of newly isolated giant viruses. Collectively, we concluded that MinION sequencing is an effective approach to rapidly perform a genome‐wide ...

Metatranscriptomics reveals a shift in microbial community composition and function during summer months in a coastal marine environment

Environmental DNA, Volume 5, Issue 5, Page 920-933, September 2023., 2023
The composition and microbial activity of marine water is expected to vary with seasons and abiotic variables. To characterize both the microbial compositional and functional changes associated with abiotic factors such as pH, temperature, alkalinity, aragonite, calcite and pCO2, here we generate a reference metatranscriptome from the Strait of Georgia,

The seminal plasma microbiome of men with testicular germ cell tumours described by small RNA sequencing

Andrology, Volume 11, Issue 4, Page 756-769, May 2023., 2023
Abstract Background It has been estimated that microorganisms are involved in the pathogenesis of approximately 20% of all cancers. Testicular germ cell tumours (TGCTs) are the most common type of malignancy in young men and arise from the precursor cell, germ cell neoplasia in situ (GCNIS).

Insights into the potential for mutualistic and harmful host–microbe interactions affecting brown alga freshwater acclimation

Molecular Ecology, Volume 32, Issue 3, Page 703-723, February 2023., 2023
Abstract Microbes can modify their hosts' stress tolerance, thus potentially enhancing their ecological range. An example of such interactions is Ectocarpus subulatus, one of the few freshwater‐tolerant brown algae. This tolerance is partially due to its (un)cultivated microbiome.

Genomics discovery of giant fungal viruses from subsurface oceanic crustal fluids

ISME Communications, 2023
The oceanic igneous crust is a vast reservoir for microbial life, dominated by diverse and active bacteria, archaea, and fungi. Archaeal and bacterial viruses were previously detected in oceanic crustal fluids at the Juan de Fuca Ridge (JdFR).

Megaviruses contain various genes encoding for eukaryotic vesicle trafficking factors

Traffic, Volume 23, Issue 8, Page 414-425, August 2022., 2022
Giant viruses enter their eukaryotic host cells by phagocytosis. For reproduction, they hijack the host cell's membranes by an unknown mechanism. Here, we found that giant viruses express several core factors of the eukaryotic vesicle fusion machinery, including SNARE, Rab, SM proteins, and the disassembly protein NSF.

The expanding Asgard archaea and their elusive relationships with Eukarya

mLife, Volume 1, Issue 1, Page 3-12, March 2022., 2022
Abstract The discovery of Asgard archaea and the exploration of their diversity over the last 6 years have deeply impacted the scientific community working on eukaryogenesis, rejuvenating an intense debate on the topology of the universal tree of life (uTol). Here, we discuss how this debate is impacted by two recent publications that expand the number
