Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, Volume 3, Issue 3, September 2026.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Evidence tiers for strain‐resolved long‐read metagenomics

iMetaOmics, Volume 3, Issue 3, September 2026.
Long‐read metagenomics links variants, repeats, and mobile elements across individual molecules and can reveal lineage turnover that is obscured at the species level. The strength of the resulting inference, however, depends on the type and genomic span of the recovered linkage. We distinguish four evidence units—strain profiles, local haplotype blocks,

Revealing Functional Traits of Insect Pest Suppressive Rhizobacterial Strains Through Comparative Genomics

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Inoculation of select rhizobacterial strains to enhance crop health is a growing field in sustainable agriculture. This study conducts a comparative genomic analysis of five plant‐beneficial rhizobacterial strains (Acidovorax radicis N35, Bacillus subtilis B171, Bacillus velezensis FZB42 Rhizobium radiobacter F4 and Pseudomonas simiae WCS417r ...

Atmospheric Microbial Transport to Antarctica and Its Ecological Implications: A Systematic Review

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Atmospheric transport to Antarctica operates via long‐range advection, marine aerosolization, and local resuspension, acting as a strict ecological filter. This selective barrier could actively shape local ecosystems by seeding them with functionally distinct, stress‐adapted microbial pioneers capable of surviving extreme conditions.

Characterization of Prophages and Their Genetic Cargo in Clinical M. abscessus Isolates

Microorganisms
Limited data exist regarding lysogenic phages carried by M. abscessus, as well as regarding their roles played in diseases. Strains identified as M. abscessus from patients were collected.

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, Volume 251, Issue 5, Page 2799-2817, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

A universe of human gut-derived bacterial prophages: unveiling the hidden viral players in intestinal microecology

Gut Microbes
Prophages, which are an existing form of temperate phages that integrate into host genomes, have been found extensively present in diverse bacterial species. The human gut microbiome, characterized by its complexity, dynamism, and interconnectivity among

Prophages and satellite prophages are widespread in Streptococcus and may play a role in pneumococcal pathogenesis

Nature Communications, 2019
Prophages are viral genomes integrated within bacterial genomes. Here, Rezaei Javan et al. identify nearly 800 prophages and satellite prophages in > 1300 Streptococcus genomes, and show that a satellite prophage is associated with virulence in a mouse ...

Comprehensive discovery and functional characterization of diverse prophages in the pig gut microbiome

Frontiers in Microbiology
Prophages, viruses integrated into bacterial or archaeal genomes, can carry cargo that confers beneficial phenotypes to the host. The porcine gut microbiota constitutes a complex, dynamic, and interconnected ecosystem, yet the distribution of prophages ...

Bacteriophages Contribute to Shaping Clostridioides (Clostridium) difficile Species

Frontiers in Microbiology, 2018
Bacteriophages (phages) are bacterial viruses that parasitize bacteria. They are highly prevalent in nature, with an estimated 1031 viral particles in the whole biosphere, and they outnumber bacteria by at least 10-fold. Hence, phages represent important
