A single transcriptional regulator is crucial for the adaptation of Staphylococcus aureus to diverse niches

Adaptation of bacterial pathogens to new hosts often involves the exchange of mobile genetic elements, or generally the highly variable accessory genome. However, adaptation to different niches is often plastic, mediated by conserved pathways in the core genome. The general stres...

Shared household environment structures the gut microbiota in a large family cohort with central areolar choroidal dystrophy

Central areolar choroidal dystrophy (CACD) is a rare monogenic hereditary retinal dystrophy characterised by progressive retinal pigment epithelium and choriocapillaris atrophy, photoreceptor loss, oxidative stress, and chronic inflammation. Emerging evidence suggests that the gu...

Synergistic Insecticidal Efficacy of the Natural Fumigant Methyl Benzoate Against Phosphine-Resistant Sitophilus oryzae

The widespread emergence of phosphine-resistant populations of stored-product pests, such as the rice weevil (Sitophilus oryzae), poses a significant challenge to effective grain protection. This study investigated the fumigation toxicity of methyl benzoate (MBe), an eco-friendly...

Gut microbial metabolism of peanuts generates immunoregulatory metabolites

Background. Complementary feeding practices and timing are thought to significantly influence early life immune development, with the early introduction of allergenic foods being especially important for prevention of food allergy. We hypothesized that allergen-containing foods s...

Informing afforestation decisions with expert knowledge on forest biodiversity

Biodiversity underpins the ecosystem services provided by forests, yet for several planting scenarios expected to play an increasing role in future afforestation, the absence of comparable biodiversity data constrains ecosystem service modelling, natural capital accounting and as...

Fermented protein foods as modulators of the gut-muscle axis: mechanisms, evidence, and future directions

Skeletal muscle has a profound influence on metabolic health, functional capacity and resilience across the lifespan. Beyond dietary protein and physical activity, the gut microbiome may have the capacity to impact skeletal muscle mass and function through the bidirectional netwo...

Examining challenges and uncertainties associated with using water table management to reduce greenhouse gas emissions from grassland peat soils

Countries with significant areas of grassland on organic soils must accurately estimate the extents of these lands to estimate greenhouse gas (GHG) emissions from them. These areas are often targeted for management change to reduce emissions reported under the Land Use, Land Use...

Genome-wide prediction and association mapping of potato common scab with historical data

Abstract Common scab, caused by Streptomyces spp., is worldwide an important skin disease of potato, capable of significant reductions in marketable value. Resistant varieties developed through phenotypic selection have been the most effective strategy thus far. Previous studies...

High-Resolution Taxonomic Assessment Using PacBio 16S rRNA Sequencing of Farm Animal Slurry, Broiler Waste and Anaerobically Digested Wastewater Treatment Sludge and Description of Soil Microbiota

The application of organic wastes as fertilisers is important for sustainable agriculture, provided that resulting changes in microbial communities do not disrupt nutrient cycling or soil fertility. To the authors’ knowledge, this study was the first to use PacBio 16S rRNA sequen...

Daily administration of Limosilactobacillus mucosae DPC 6426 had negligible effects on blood lipids in mildly hypercholesterolaemic adults

Abstract Among the recommendations to prevent heart disease is the maintenance of normal blood cholesterol levels, through the consumption of a cardioprotective diet, and if necessary, the use of therapeutics such as statins. Alterations in the gut microbiota have previously been...

Quantification of nitrous oxide (N2O) emissions in a managed grassland following nitrogen fertilisation: A comparative analysis of cumulative emissions determined by automated and manual chamber methods

Accurate quantification of nitrous oxide (N 2 O) emissions from grasslands remains challenging owing to their episodic, spatially heterogeneous and diurnally variable nature. This study compared automated chamber (AC) and manual chamber (MC) methods to evaluate the influence of c...

Use of Chondrus crispus Stakehouse Hydrolysate for Functional, Nutritional, and Potential Bioactive Health Benefits and Demonstration of Use as an Emulsifier in Selected Baked Goods

An increase in flexitarians, vegetarians, and vegan consumers coupled with soaring egg prices post covid has increased demand in the food industry for alternative ingredients, including emulsifier products. Plant-derived emulsifiers, including chickpea aquafaba and oat proteins,...

Reconsidering the importance of M etopolophium dirhodum ( W alker) ( H emiptera: A phididae) as a crop pest

Abstract Barley yellow dwarf virus (BYDV) causes major yield losses in temperate cereals. In many regions, management of BYDV has focused on Rhopalosiphum padi as the primary vector of BYDV‐PAV and Sitobion avenae as the primary vector of BYDV‐MAV. By contrast, the significance o...
