Transcriptional landscape of the cell cycle in a model thermoacidophilic archaeon reveals similarities to eukaryotes Open
Similar to many eukaryotes, the thermoacidophilic archaeon Saccharolobus islandicus follows a defined cell cycle program, with two growth phases, G1 and G2, interspersed by a chromosome replication phase (S), and followed by genome segrega…

New groups of highly divergent proteins in families as old as cellular life with important biological functions in the ocean Open
Background Metagenomics has considerably broadened our knowledge of microbial diversity, unravelling fascinating adaptations and characterising multiple novel major taxonomic groups, e.g. CPR bacteria, DPANN and Asgard archaea, and novel v…

Interspecific interactions and aging: Prediction of gerogenic bacteria and critical human protein targets of microbial infections Open
Bacteria permeate every niche of the human body with major consequences on our health and senescence that have not been fully described. Here, we predict which bacteria and which bacterial proteins could interfere with proteins associated …

Transcriptional landscape of the archaeal cell cycle is broadly conserved in eukaryotes Open
The cell cycle is a series of events that occur from the moment of cell birth to cell division. In eukaryotes, cell growth, genome replication, genome segregation, and cytokinesis are strictly coordinated, defining discrete cell cycle phas…

The ageing virus hypothesis: Epigenetic ageing beyond the Tree of Life Open
A recent thought‐provoking theory argues that complex organisms using epigenetic information for their normal development and functioning must irreversibly age as a result of epigenetic signal loss. Importantly, the scope of this theory co…

The evosystem: A centerpiece for evolutionary studies Open
In this paper, we redefine the target of evolutionary explanations by proposing the “evosystem” as an alternative to populations, lineages and species. Evosystems account for changes in the distribution of heritable variation within indivi…

A broadly distributed new class of quorum sensing signals mediate bacterial intercellular signaling Open
The gram-positive bacteria use quorum sensing secreted peptides to communicate and control critical bacterial phenotypes. All the bacterial peptides are produced in a longer inactive form that is secreted and processed into shorter active …

Bursts of novel composite gene families at major nodes in animal evolution Open
A molecular level perspective on how novel phenotypes evolve is contingent on our understanding of how genomes evolve through time, and of particular interest is how novel elements emerge or are lost. Mechanisms of protein evolution such a…

Large-Scale Identification of Known and Novel RRNPP Quorum-Sensing Systems by RRNPP_Detector Captures Novel Features of Bacterial, Plasmidic, and Viral Coevolution Open
Gram-positive Firmicutes bacteria and their mobile genetic elements (plasmids and bacteriophages) encode peptide-based quorum-sensing systems (QSSs) that orchestrate behavioral transitions as a function of population densities. In their si…

Interactomics: Dozens of Viruses, Co-evolving With Humans, Including the Influenza A Virus, may Actively Distort Human Aging Open
Some viruses (e.g., human immunodeficiency virus 1 and severe acute respiratory syndrome coronavirus 2) have been experimentally proposed to accelerate features of human aging and of cellular senescence. These observations, along with evol…

Proximate Drivers of Population-Level Lizard Gut Microbial Diversity: Impacts of Diet, Insularity, and Local Environment Open
Diet has been suggested to be an important driver of variation in microbiota composition in mammals. However, whether this is a more general phenomenon and how fast changes in gut microbiota occur with changes in diet remains poorly unders…

Hundreds of Out-of-Frame Remodeled Gene Families in the<i>Escherichia coli</i>Pangenome Open
All genomes include gene families with very limited taxonomic distributions that potentially represent new genes and innovations in protein-coding sequence, raising questions on the origins of such genes. Some of these genes are hypothesiz…

For consideration as an Article in the Discoveries section of MBE Aging at evolutionary crossroads: longitudinal gene co-expression network analyses of proximal and ultimate causes of aging in bats Open
How, when and why do organisms, their tissues and their cells age remain challenging issues, although researchers have identified multiple mechanistic causes of aging, and three major evolutionary theories have been developed to unravel th…

Gram-positive bacteria (e.g. Firmicutes) and their mobile genetic elements (plasmids, bacteriophages) encode peptide-based quorum sensing systems (QSSs) that regulate behavioral transitions in a density-dependent manner. In their simplest …

Large-scale identification of viral quorum sensing systems reveals density-dependent sporulation-hijacking mechanisms in bacteriophages Open
Communication between viruses supported by quorum sensing systems (QSSs) were found to optimize the fitness of temperate bacteriophages of Bacilli by guiding the transition from the host-destructive lytic cycle to the host-protective lysog…

The Epistemic Revolution Induced by Microbiome Studies: An Interdisciplinary View Open
Many separate fields and practices nowadays consider microbes as part of their legitimate focus. Therefore, microbiome studies may act as unexpected unifying forces across very different disciplines. Here, we summarize how microbiomes appe…

Interspecific interactions that affect ageing: Age-distorters manipulate host ageing to their own evolutionary benefits Open
Genetic causes for ageing are traditionally investigated within a species. Yet, the lifecycles of many organisms intersect. Additional evolutionary and genetic causes of ageing, external to a focal species/organism, may thus be overlooked.…
