The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Beyond Biodiversity: Incorporating Uncertainty Into Metabarcoding Data for Improved Inference of Ecological Relationships

Molecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Metabarcoding sequence data from environmental DNA (eDNA) is rapidly expanding as a powerful method for biodiversity surveys. In order to interpret these data, tools are needed that account for the uncertainty associated with eDNA sampling, sequencing and analysis.

Biowaste Composting as a Sustainable Platform for Bacterial CO Production: Evidence From cooS Gene Expression and Microbial Community Profiling

GCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates, for the first time, the expression of the cooS gene during composting, confirming microbial CO production under mesophilic conditions. The results highlight composting as a novel waste‐to‐biochemicals process, offering a sustainable, low‐carbon pathway for generating carbon monoxide via bacterial CO dehydrogenase activity ...

Spatial Distributions of Active Pico- and Nano-Haptophytes (Eukaryota, Hacrobia) in the Tropical and Subtropical Western Pacific Ocean

Microorganisms
Haptophytes are ubiquitous single-celled eukaryotic plankton in coastal and open oceans that play a key role in marine biogeochemical cycling. Understanding the size structure and community composition of active haptophytes is crucial for elucidating ...

The Morphology and Small Subunit rDNA Gene Phylogeny of the Novel Goniomonad Genus Ebisugoniomonas and Two Novel Poseidogoniomonas Species

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Goniomonads are representatives of Cryptista. They are morphologically and genetically diverse, comprising nine genera described so far. 18S rDNA data has revealed at least one more monophyletic genus‐level lineage, as well as novel species within currently described genera. The molecular diversity of goniomonads is not fully investigated, and

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts

Advanced Science, Volume 13, Issue 24, 27 April 2026.
We present the Microbial General Model (MGM), a transformer‐based foundation model pretrained on over 260,000 microbiome samples. MGM learns contextualized microbial representations via self‐supervised language modeling, enabling robust transfer learning, cross‐regional generalization, keystone taxa discovery, and prompt‐guided generation of realistic,

Ancient and novel small RNA pathways compensate for the loss of piRNAs in multiple independent nematode lineages.

PLoS Biology, 2015
Small RNA pathways act at the front line of defence against transposable elements across the Eukaryota. In animals, Piwi interacting small RNAs (piRNAs) are a crucial arm of this defence.

The early-acting glycosome biogenic protein Pex3 is essential for trypanosome viability

Life Science Alliance, 2019
This study reports the identification of trypanosome Pex3, the master regulator of glycosome biogenesis. Trypanosome Pex3 is essential for glycosome assembly and trypanosome viability and is distinct from human Pex3.

Demographic History and Genetic Diversity of Rātā Moehau (Metrosideros bartlettii; Myrtaceae), a Critically Endangered Aotearoa New Zealand Endemic Tree

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Rātā Moehau (Metrosideros bartlettii), a critically endangered tree endemic to Aotearoa New Zealand, is represented by only 14 wild individuals. We assembled its first genome, analysed genetic diversity in wild and cultivated individuals and found long‐term population decline and reduced diversity in cultivated plants—providing key insights to support ...
