Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Dynamic disorder is crucial for mitochondrial protein import

Protein Science, Volume 35, Issue 6, June 2026.
Abstract The import of proteins into mitochondria poses fundamental mechanistic challenges: aggregation‐prone precursor proteins must be maintained in aqueous compartments and threaded through narrow pores without becoming stuck or mislocalized. Recent evidence from mitochondrial protein import studies and other chaperone systems underscores the ...

The structures of two archaeal type IV pili illuminate evolutionary relationships

, 2020
International audienceWe have determined the cryo-electron microscopic (cryo-EM) structures of two archaeal type IV pili (T4P), from Pyrobaculum arsenaticum and Saccharolobus solfataricus, at 3.8 Å and 3.4 Å resolution, respectively.

Genomic Map of Escherichia coli and Single Nucleotide Polymorphism Markers in Colorectal Cancer

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
This study identified colorectal cancer‐associated SNPs in Escherichia coli using PacBio full‐genome sequencing, establishing a highly accurate SNP‐based model for non‐invasive colorectal cancer risk prediction. ABSTRACT Gut microbial single nucleotide polymorphisms (SNPs) offer stable, specific genetic markers for disease diagnosis.

Archaeal Viruses and Their Interactions with CRISPR-Cas Systems

, 2020
Our knowledge of archaeal viruses has increased rapidly over the past four decades since the discovery of the archaeal domain. Most surprising has been the morphological diversity of crenarchaeal viruses that generate several forms not previously ...

The infection cycle of the haloarchaeal virus HFTV1 is tightly regulated and strongly inhibits motility of its host

mSystems
Although viruses have been shown to infect all domains of life, our understanding of the genetic program behind the exploitation of host resources to produce progeny virions is thus far limited to several bacterial viruses.

CRISPR-mediated gene silencing reveals involvement of the archaeal S-layer in cell division and virus infection

Nature Communications, 2019
The S-layer is a proteinaceous envelope often found in bacterial and archaeal cells. Here, the authors use CRISPR-based technology to silence slaB, encoding the S-layer membrane anchor, to show that an intact S-layer is important for cell division and ...

Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

New archaeal viruses discovered by metagenomic analysis of viral communities in enrichment cultures

, 2018
International audienceViruses infecting hyperthermophilic archaea of the phylum Crenarchaeota display enormous morphological and genetic diversity, and are classified into 12 families.
