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.

Assessing the biogeography of marine giant viruses in four oceanic transects

ISME Communications, 2023
Viruses of the phylum Nucleocytoviricota are ubiquitous in ocean waters and play important roles in shaping the dynamics of marine ecosystems. In this study, we leveraged the bioGEOTRACES metagenomic dataset collected across the Atlantic and Pacific ...

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

Comparative Genomics and Environmental Distribution of Large dsDNA Viruses in the Family Asfarviridae

Frontiers in Microbiology, 2021
The family Asfarviridae is a group of nucleo-cytoplasmic large DNA viruses (NCLDVs) of which African swine fever virus (ASFV) is well-characterized. Recently the discovery of several Asfarviridae members other than ASFV has suggested that this family ...

Giant Virus Infection Signatures Are Modulated by Euphotic Zone Depth Strata and Iron Regimes of the Subantarctic Southern Ocean

mSystems, 2023
Viruses can alter the abundance, evolution, and metabolism of microorganisms in the ocean, playing a key role in water column biogeochemistry and global carbon cycles. Large efforts to measure the contribution of eukaryotic microorganisms (e.g., protists)

Discovery of Viral Myosin Genes With Complex Evolutionary History Within Plankton

Frontiers in Microbiology, 2021
Nucleocytoplasmic large DNA viruses (NCLDVs) infect diverse eukaryotes and form a group of viruses with capsids encapsulating large genomes. Recent studies are increasingly revealing a spectacular array of functions encoded in their genomes, including ...

Giant Virus-Eukaryote Interactions as Ecological and Evolutionary Driving Forces

mSystems, 2021
Giant DNA viruses of eukaryotes are notable for their extraordinary genome size and coding capacity. Once thought to be oddities in the virus world, these elusive microbes have turned out to be widely occurring in marine, freshwater, and terrestrial ...
