Tracing the paths of modular evolution by quantifying rearrangement events of protein domains

open access: yesBMC Ecology and Evolution
Background Protein evolution is central to molecular adaptation and largely characterized by modular rearrangements of domains, the evolutionary and structural building blocks of proteins.

The largest reservoir of mitochondrial introns is a relic of an ancestral split gene [PDF]

open access: yes, 2010
In eukaryotes, introns are located in nuclear and organelle genes from several kingdoms (ref. 1-4). Large introns (0.1 to 5 kbp) are frequent in mitochondrial genomes of plant and fungi (ref.

Mass Spectrometry in the Elucidation of the Glycoproteome of Bacterial Pathogens [PDF]

open access: yes, 2010
Presently some three hundred post-translational modifications are known to occur in bacteria in vivo. Many of these modifications play critical roles in the regulation of proteins and control key biological processes.

Mouse genome engineering uncovers 18 genes dispensable for male reproduction

open access: yesAndrology, Volume 14, Issue 3, Page 833-846, March 2026.
Abstract Background Male infertility is an intricate multifactorial disease involving the interplay between genetic and environmental factors. Genetic anomalies account for more than 15% of all male infertility cases; however, diagnosing them exhibits enormous challenges due to variable symptomatic presentations and limited knowledge of gene functions.

River Microbiomes as Sentinels of National‐Scale Freshwater Ecosystems

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
River biofilms are complex microbial assemblages that underpin aquatic food webs and play a central role in biogeochemical cycling. By responding to environmental signals over space and time, biofilm microbial communities can act as sensitive indicators of river health.

Genetic Features of the Scuticociliate Pathogen Philaster sp. Isolate FWC2 That Causes Sea Urchin Mass Mortality

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT A scuticociliate most closely related to Philaster apodigitiformis caused mass mortalities of diadematoid sea urchins and was cultured as Philaster sp. isolate FWC2. We sequenced the metagenomic content of this isolate, which was predicted to represent ≤ 56% of the complete genome.

Skin Colour in Salamanders Is Modulated by Both Epitranscriptomic Methylation and Gene Expression

open access: yesMolecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Animal colouration is a key trait in organismal biology, being involved in natural and sexual selection, competition, and communication. Amphibians use their highly diverse colouration in many ecological interactions, but the molecular bases of their colour variation are less well understood than in other vertebrate systems. While the genetic,

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

open access: yesPLoS 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 Rhus chinensis Genome Provides Insights Into Tannin, Flavonoid Biosynthesis, and Glandular Trichome Development

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 988-1013, March 2026.
ABSTRACT The “salt tree”, Rhus chinensis, holds significant economic and medicinal value due to its ability to produce Galla chinensis (Chinese gall/gallnut), a plant‐derived medicinal material used in both traditional Chinese and modern medicine that is rich in tannins and flavonoids. It is also renowned for its remarkable stress tolerance.
