Genome-resolved biogeography of Phaeocystales, cosmopolitan bloom-forming algae [PDF]

Nature Communications
Phaeocystales, comprising the genus Phaeocystis and an uncharacterized sister lineage, are nanoplanktonic haptophytes widespread in the global ocean. Several species form mucilaginous colonies and influence key biogeochemical cycles, yet their underlying

Guarani Virophage, a New Sputnik-Like Isolate From a Brazilian Lake

Frontiers in Microbiology, 2019
Virophages are critical regulators of viral population dynamics and potential actors in the stability of the microbial networks. These small biological entities predate the replicative cycle of giant viruses, such as the members of the Mimiviridae family

Open questions in the social lives of viruses

Journal of Evolutionary Biology, Volume 36, Issue 11, Page 1551-1567, November 2023., 2023
Social interactions among viruses are diverse and pervasive, with the potential to affect every stage of the viral lifecycle. Here, we explore some of the challenges and opportunities that these interactions present for evolutionary biology. Abstract Social interactions among viruses occur whenever multiple viral genomes infect the same cells, hosts ...

Metabolic reconstruction of the near complete microbiome of the model sponge Ianthella basta

Environmental Microbiology, Volume 25, Issue 3, Page 646-660, March 2023., 2023
Abstract Many marine sponges host highly diverse microbiomes that contribute to various aspects of host health. Although the putative function of individual groups of sponge symbionts has been increasingly described, the extreme diversity has generally precluded in‐depth characterization of entire microbiomes, including identification of syntrophic ...

Presence of CRISPR CAS‐Like Sequences as a Proposed Mechanism for Horizontal Genetic Exchanges between Trichomonas vaginalis and Its Associated Virus: A Comparative Genomic Analysis with the First Report of a Putative CRISPR CAS Structures in Eukaryotic Cells

BioMed Research International, Volume 2023, Issue 1, 2023., 2023
Introduction. Trichomonas vaginalis genome is among the largest genome size and coding capacities. Combinations of gene duplications, transposon, repeated sequences, and lateral gene transfers (LGTs) have contributed to the unexpected large genomic size and diversity. This study is aimed at investigating genomic exchange and seeking for presence of the

Bacteriophages pass through candle‐shaped porous ceramic filters: Application for the collection of viruses in soil water

MicrobiologyOpen, Volume 11, Issue 5, October 2022., 2022
This study proposes to use porous candles as a new tool for collecting soil water viruses. In the first step, the passage of model viruses through the ceramic part of the candles was investigated. Regarding the field application, the experiments carried out showed a successful recovery of viruses, demonstrating the relevance and efficiency of such a ...

Infection by dsRNA viruses is associated with enhanced sporulation efficiency in Saccharomyces cerevisiae

Ecology and Evolution, Volume 12, Issue 1, January 2022., 2022
Sporulation in yeast is induced by starvation; resource exploitation by endosymbiont should induce earlier sporulation. We find that the presence of two dsRNA viruses is linked to enhanced sporulation in Saccharomyces cerevisiae. However, further research is required to determine whether high sporulation leads to infection or infection leads to higher ...

Ancient saltern metagenomics: tracking changes in microbes and their viruses from the underground to the surface

Environmental Microbiology, Volume 23, Issue 7, Page 3477-3498, July 2021., 2021
Summary Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral and prokaryotic assemblages present in the hypersaline springs that dissolve Triassic‐Keuper evaporite rocks and feed the ...

Micro-eukaryotic diversity in hypolithons from Miers Valley, Antarctica [PDF]

, 2013
The discovery of extensive and complex hypolithic communities in both cold and hot deserts has raised many questions regarding their ecology, biodiversity and relevance in terms of regional productivity.
