Diversity of FAAL enzymes and prediction of their substrate specificity using FAALPred

Protein Science, Volume 35, Issue 2, February 2026.
Abstract FAALs (fatty acyl‐AMP ligases) recruit and incorporate fatty acids during the biosynthesis of secondary metabolites. Their diversity, distribution, and substrate specificity remain poorly understood, which limits functional predictions from sequence data.

Antimicrobial Peptides, Polymorphic Toxins, and Self-Nonself Recognition Systems in Archaea: an Untapped Armory for Intermicrobial Conflicts

mBio, 2019
Numerous, diverse, highly variable defense and offense genetic systems are encoded in most bacterial genomes and are involved in various forms of conflict among competing microbes or their eukaryotic hosts.

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Structures of Saccharolobus solfataricus initiation complexes with leaderless mRNAs highlight archaeal features and eukaryotic proximity

Nature Communications
The archaeal ribosome is of the eukaryotic type. TACK and Asgard superphyla, the closest relatives of eukaryotes, have ribosomes containing eukaryotic ribosomal proteins not found in other archaea, eS25, eS26 and eS30.

Navigating the archaeal frontier: insights and projections from bioinformatic pipelines

Frontiers in Microbiology
Archaea continues to be one of the least investigated domains of life, and in recent years, the advent of metagenomics has led to the discovery of many new lineages at the phylum level.

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

Airborne Bacterial Communities: Diversity, Survival Strategies and Functional Roles in the Atmosphere

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This mini‐review synthesises evidence on the taxonomic patterns of airborne microorganisms and the selective pressures they face. We highlight key conserved physiological traits, such as DNA repair and desiccation tolerance, which enable stress‐tolerant members to survive and suggest their potential for activity within the atmospheric environment ...

Nuclear DNA of plastid origin (NUPTs), neglected driver of genome variation and evolutionary innovation

The Plant Journal, Volume 125, Issue 3, February 2026.
Significance Statement Contrary to expectation, NUPTs do not necessarily have a deleterious or ultimately neutral impact, nor are they necessarily purged from the genome. Instead, they can proliferate and eventually become fixed, generating new and novel genes, gene regions and regulatory elements, thereby significantly contributing to plant nuclear ...
