Despite extensive research on tillage and its impact on nematode communities, little is known about the impact of occasional tillage within no-tillage practices. Occasionally tilling the soil can minimize the negative effects of conventional tillage and no-tillage practices especially in clayey soils. A tillage system that maximizes all the economic and environmental benefits but increases herbivore nematodes while reducing beneficial free-living nematodes may pose long-term agronomic challenges.

Pervasive but biome-dependent relationship between fragmentation and resilience in forests.

Nat Ecol Evol

September 2025

State Key Laboratory for Ecological Security of Regions and Cities, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, China.

The relationship between landscape fragmentation and vegetation resilience is uncertain. Here we use multiple satellite-based tree cover data and vegetation indices to quantify the apparent effects of fragmentation on global forest resilience and potential mechanisms thereof. We measure fragmentation as edge density, patch density and mean patch area of tree cover patches, and measure resilience as one-lag temporal autocorrelation of vegetation indices.

Overexpression of the ABA Synthesis Gene OsABA2 Enhances Seed Storability in Rice.

Rice (N Y)

July 2025

State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Rice Research Institute, Sichuan Agricultural University, Chengdu, 611130, China.

Seed storability is critical for seed production and germplasm conservation. Numerous studies have linked seed storability to abscisic acid (ABA) metabolism; however, the use of biotechnological approaches to strategically and rapidly enhance seed storability in rice through manipulation of ABA biosynthesis genes remains unexplored. In the current study, we developed overexpression lines (OE) of OsABA2, which encodes a XANTHOXIN DEHYDROGENASE, a key enzyme in the ABA synthesis pathway.

Through mechanistic analyses of protein structure and interfacial properties, this study revealed that both pasteurization and freeze-thaw treatments decreased the foaming capacity (FC) of egg white to 265 % and 95 %, respectively, by inducing protein aggregation due to thermal or ice crystal damage. To address this, trypsin and papain hydrolysis were employed to depolymerize pasteurized egg white (PEW) and five freeze-thaw cycles treated egg white (FT-5). The maximum FC (403 %) achieved with a 60-min trypsin treatment.

Apple replant disease (ARD) describes a phenomenon of reduction of crop productivity in the early years of orchard establishment on sites previously planted with apple. Currently, manipulation of the soil microbiome through (bio)fumigation is the primary approach to alleviate ARD. An alternative approach to combat ARD, could involve adjusting the rootstock microbiome to better cope with biotic stress present in orchard soil.

Iron supplementation has been an important and complicated health topic. Available iron preparations generally have issues such as instability, inadequate absorption, and low consumer acceptability. This study provided a novel ferric pyrophosphate (FePP) delivery system, the FePP-casein-phosphopeptide-dextran (FCD) complex, with sodium pyrophosphate (NaPP) as a solvent promoter and casein-phosphopeptide (CPP) and β-glucan as wall materials.

Strain CNRZ32 of Lactobacillus helveticus was grown in chemically defined medium or milk, and its exopolysaccharide (EPS) was isolated from the supernatant or the whole culture and purified by TCA and acetone precipitations and solvent extractions. Purity was checked by gel permeation chromatography. The molecular mass determined by size-exclusion chromatography was 6.

: Sustained drug exposure is a key factor in the treatment of patients infected with human immunodeficiency virus (HIV) or hepatitis B virus (HBV) in order to achieve the intended virological response. Although influenced also by other parameters, adherence to the treatment scheme is the most important for adequate drug exposure. This can be assessed by therapeutic drug monitoring (TDM).

: Rivaroxaban, an oral anticoagulant, shows poor aqueous solubility, posing significant challenges to its bioavailability and therapeutic efficiency. The present study investigates the improvement of rivaroxaban's solubility through the formation of different inclusion complexes with three cyclodextrin derivatives, such as β-cyclodextrin (β-CD), methyl-β-cyclodextrin (Me-β-CD), and hydroxypropyl-β-cyclodextrin (HP-β-CD) prepared by lyophilization in order to stabilize the complexes and improve dissolution characteristics of rivaroxaban. : The physicochemical properties of the individual compounds and the three lyophilized complexes were analysed using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA).

Consumers' confidence in products of animal origin is highly subjected to the quality guarantees offered by the manufacturing and retail industries. Traditionally, meat quality evaluation has been conducted through destructive, time-consuming and chemical-dependent protocols. Smart methodologies based on the non-destructiveness and/or non-contact with the samples, such as spectroscopy-based technologies, arise as an alternative promising tool.

Potyviridae is the largest family of plant-infecting RNA viruses. All members of the family (potyvirids) have single-stranded positive-sense RNA genomes, with polyprotein processing as the expression strategy. The 5'-proximal regions of all potyvirids, except bymoviruses, encode two types of leader proteases: the serine protease P1 and the cysteine protease HCPro.

This study identified genomic variants and potential candidate genes associated with 11 primal cut traits (back fat, belly fat, total fat, loin fat, ham fat, picnic fat, butt fat, loin intramuscular fat content, ham side fat, shoulder dorsal fat, and belly side fat thicknesses) in Canadian commercial crossbred pigs. Genome-wide association studies using whole genome sequencing data were conducted using genotyping data from 1118 commercial crossbred pigs. This analysis revealed multiple QTLs across chromosomes SSC1, 2, 3, 6, 7, 9, 14, 15, and 17, associated with fat traits.

The One Health (OH) approach recognizes the interconnectedness of the health of people, animals, plants/crops and ecosystems, and is central to addressing antimicrobial resistance (AMR). The 7th Environmental Dimension of Antimicrobial Resistance Conference (EDAR7), held in Montreal in May 2024, exemplified this approach by convening international experts and stakeholders to discuss AMR research and policy progress. EDAR7 workshop #8 focused on (1) barriers to establishing effective OH AMR research programs, (2) gaps in OH AMR research priorities, and (3) potential solutions/approaches or "tools" to ensure programs develop in accordance with OH principles and generate insightful data that maximizes limited resources.
