The need for high-resolution gut microbiome characterization to design efficient strategies for sustainable aquaculture production

This study evaluates microbiota-directed fibers (MDFs) in Atlantic salmon diets, finding negligible effects on gut microbiome and host physiology, but identifying potential endogenous lactic acid bacteria for future MDF strategies.

The role of transposon activity in shaping cis-regulatory element evolution after whole genome duplication

This study investigates how transposon activity and whole genome duplication interact to shape cis-regulatory element evolution in Atlantic salmon, finding a strong link between TE insertions during WGD and TE-CRE evolution.

The Salmon Microbial Genome Atlas enables novel insights into bacteria-host interactions via functional mapping

The paper presents the Salmon Microbial Genome Atlas, a collection of bacterial genomes from Atlantic salmon, and functionally characterizes key gut microbiota populations involved in nutrient processing and health.

High radiosensitivity in the conifer Norway spruce (Picea abies) due to lesscomprehensive mobilisation of protection and repair responses compared to the radiotolerant Arabidopsis thaliana

This study compares radiosensitivity between Norway spruce and Arabidopsis thaliana, finding that Norway spruce has less comprehensive mobilization of protection and repair responses to gamma radiation.

Metabolic influence of core ciliates within the rumen microbiome

The paper investigates the metabolic roles of core ciliates in the rumen microbiome, finding that they contribute significantly to volatile fatty acid production and hydrogen metabolism, particularly in high methane-emitting animals.

Functional validation of transposable element derived cis-regulatory elements in Atlantic salmon

The paper evaluates the gene regulatory functions of transposable elements (TEs) in Atlantic salmon, finding that some TE-derived cis-regulatory elements significantly increase gene expression.

What can cold-induced transcriptomes of Arctic Brassicaceae tell us about the evolution of cold tolerance?

The paper compares cold-induced transcriptomes of three Arctic Brassicaceae species to Arabidopsis thaliana to understand cold tolerance evolution and find shared and species-specific gene responses.

Identification of new growth regulators using cross-species network analysis in plants

Cross-species network analysis identifies and validates new growth regulators in Arabidopsis by integrating transcriptional networks and functional orthologs.

Populus ERF85 balances xylem cell expansion and secondary cell wall formation in hybrid aspen

This study identifies ERF85's role in balancing xylem cell expansion and secondary cell wall formation in hybrid aspen through ectopic expression analysis and transcriptomic profiling.

A novel dual enrichment strategy provides soil- and digestate- competent N2O-respiring bacteria for mitigating climate forcing in agriculture

The paper develops a dual enrichment strategy to isolate N2O-respiring bacteria capable of functioning in both soil and digestate, showing their effectiveness in reducing N2O emissions.

Microbiota-directed fibre activates both targeted and secondary metabolic shifts in the distal gut.

This study shows that a tailored acetylated galactoglucomannan fibre selectively activates butyrate-producing gut bacteria and triggers secondary metabolic shifts in neighboring microbial populations in pigs.

Comparative regulomics reveals pervasive selection on gene dosage following whole genome duplication

The paper uses comparative phylogenetic analysis of transcriptomic data to show pervasive expression evolution in ohnologs following salmonid WGD, driven by regulatory divergence and gene dosage shifts.

Integration of absolute multi-omics reveals translational and metabolic interplay in mixed-kingdom microbiomes.

The paper integrates absolute multi-omics data to study metabolic and translational interactions in a mixed-kingdom microbiome, revealing population-specific transcriptome-proteome relationships.

From proteins to polysaccharides: lifestyle and genetic evolution of Coprothermobacter proteolyticus.

This study reveals that Coprothermobacter proteolyticus acquires carbohydrate-active enzymes via horizontal gene transfer to degrade polysaccharides, explaining its dominance in thermophilic microbial communities.

Evolution of cold acclimation in temperate grasses (Pooideae)

This study investigates cold acclimation in early diverging Pooideae lineages and finds that while cold acclimation exists, regulatory genes are not conserved and show lineage-specific evolution.

Ethylene signaling induces gelatinous layers with typical features of tension wood in hybrid aspen

This study shows ethylene induces gelatinous layers in hybrid aspen, linking ethylene signaling to wood formation through transcription factors.

Subfunctionalization versus neofunctionalization after whole-genome duplication

This paper shows that differing conclusions about gene regulatory divergence after whole-genome duplication are due to analysis methods, not data differences.

Life stage associated remodeling of lipid metabolism regulation in the duplicated Atlantic salmon genome

The paper investigates how diet shifts between freshwater and seawater affect lipid metabolism regulation in Atlantic salmon, identifying gene expression changes and evolutionary impacts of whole-genome duplication.

AspWood: High-spatial-resolution transcriptome profiles reveal uncharacterized modularity of wood formation in Populus tremula

The paper generates high-spatial-resolution transcriptome data from Populus tremula wood-forming tissues and identifies novel gene modules and expression patterns involved in cambial growth and wood formation.
