A GacS-mediated regulatory framework coordinates bacterial competition and rhizosphere microbiome remodeling in Pseudomonas fluorescens

Plant growth-promoting Pseudomonas bacteria are promising biocontrol agents whose regulatory and effector genes shape bacterial traits involved in interactions with host plants and soil microorganisms. However, previous research has predominantly examined individual genes or trai...

Intelligent Greenhouse Temperature Management: A Closed-Loop Perspective on Sensing, Modeling, Control, and Deployment

Greenhouse cultivation plays an important role in food security, resource-use efficiency, and sustainable agricultural development. Temperature management is particularly critical because it directly affects crop growth, yield and quality, energy consumption, and environmental co...

Synthetic DNA Tracers Enable Ultra-High-Reproducibility Characterization of Aquifer Hydraulic Conductivity and Contaminant Transport

Abstract Reliable characterization of aquifer hydraulic conductivity (K) via tracer-based methods remains a major challenge due to environmental background noise. We report that synthetic DNA tracers, free of background-noise interference, enable highly reproducible tomographic i...

Detection of Mitochondrial Respiratory Chain Complexes by BN‐PAGE and Its Applications

ABSTRACT Blue native polyacrylamide gel electrophoresis (BN‐PAGE) is a core technique for separating and characterizing plant mitochondrial respiratory chain complexes. Under mild, nondenaturing conditions, Coomassie brilliant blue G‐250 binds to membrane protein complexes, impar...

Effects of Sulfur Dioxide on Disease Resistance and Storage Quality of Durian (Durio zibethinus L.): A Comprehensive Analysis Integrating GC-IMS, HTS, Physiological and Biochemical Parameters

In this study, we examined the multifaceted effects of sulfur dioxide (SO2) on the postharvest preservation of durian and the underlying potential mechanism of disease resistance. Our results show that 2% SO2 preserved the good quality of durian by inhibiting its respiration rate...

Hukou system reform, agricultural production transformation and China’s food security

This paper explores how accelerated agricultural labour migration affects China’s grain output and how its underlying channels differ in the short and long run. Launched in 2011, the hukou system reform eased restrictions on rural labourers settling in urban areas. Using provinci...

Revolutionizing drought defense: The water-plant-microbe synergy in climate-smart agriculture

Global warming-induced water scarcity threatens agricultural sustainability. While precision irrigation and microbial inoculants are recognized as effective individual strategies, their synergistic potential remains under-explored. This review synthesizes recent advances in the "...

Assessing Deep Maturity of Compost: Relative Cotyledon Chlorophyll as a Complementary Indicator in Full-Scale Cow Manure Composting

Compost maturity is commonly assessed using the seed germination test, which mainly reflects below-ground radicle growth. However, composts that meet conventional maturity criteria may still inhibit above-ground seedling development. This study assessed the deep maturity of compo...

Evaluating Greenhouse Tomato Responses to High Temperature Using AquaCrop-OSPy with Sequential Sensitivity Analysis and GLUE Calibration

How to precisely depict the effects of high temperature on greenhouse crop growth and yield formation and derive optimal irrigation schedules remains an emerging challenge for current crop models. To address this issue, our study focused on drip-irrigated tomato plants grown in a...

The Function of C-Terminal Pentapeptide in Allatostatin Type-C: Regulating Growth and Development by Affecting Juvenile Hormone Biosynthesis in Ostrinia furnacalis

Abstract Allatostatin Type-C (AstC) is an insect neuropeptide involved in developmental regulation, but whether its conserved C-terminal pentapeptide, PISCF, remains bioactive as an isolated fragment is unclear. Herein, the synthetic PISCF was evaluated on the Asian corn borer, O...

A Tocopherol-Related Methyltransferase SlVTE3(2) Regulates Tomato Fruit Ripening and Tocopherol Accumulation

Abstract Tomato fruit ripening is a critical developmental process that determines the fruit quality. However, the regulatory mechanisms underlying the ripening initiation remain incompletely understood. Here, we characterized SlVTE3(2), a tocopherol-biosynthesis-related methyltr...

Platelet‐rich plasma exhibits antibacterial and anti‐inflammatory effects in an in vitro donkey endometritis model

Abstract Background Infectious endometritis, mainly caused by Escherichia coli ( E. coli ) and Streptococcus equi subsp. zooepidemicus ( SEZ ), significantly impairs donkey reproductive performance. Platelet‐rich plasma (PRP) shows promise as an anti‐inflammatory and antibiotic a...

Process-Model-Supported Offline Reinforcement Learning for Water–Fertilizer Management: Two-Model Closed-Loop Production–Nitrogen-Loss Trade-Offs

Nitrogen leaching threatens groundwater quality, making production retention and efficient water–fertilizer use joint management priorities. Field trials evaluate a limited set of treatments, while adaptive policies generate long sequences of decisions. We propose counterfactual...

Dynamic Assessment and Synergistic Reconfiguration of Rural Territorial System Resilience: A Case Study of Quzhou County, China

Rapid urbanization is widely regarded as a major pathway to rural development through improved market accessibility, infrastructure provision, and urban–rural functional linkages. Yet long-term empirical evidence has not sufficiently tested whether urban proximity enhances or ero...

Composting rural kitchen waste for nutrient recovery and runoff pollution mitigation: a Bayesian modeling approach

In China’s ecologically sensitive Erhai Basin, open-dumped rural kitchen waste causes both nutrient loss and water quality degradation. Here we integrate household surveys, on-site composting experiments, and a Bayesian dual-pool wash-off model in a pilot case study of six villag...

Stability and Hopf Bifurcation Analysis of an Age-Structured SVIRS Epidemic Model with Temporary Immunity

In this paper, we investigate an SVIRS epidemic model that incorporates both temporary immunity and an age-structured recovery process. By reformulating the system as a nondensely defined abstract Cauchy problem, we establish the existence and uniqueness of solutions and derive t...

Endoplasmic reticulum-associated NcDYRK2 regulates Ca2⁺ dynamics, motility, and development gene expression in Neospora caninum

Neospora caninum is an obligate intracellular apicomplexan parasite and a leading cause of bovine abortion worldwide, imposing substantial economic losses on the cattle industry. Dual-specificity tyrosine phosphorylation-regulated kinases (DYRKs) are highly conserved serine/threo...

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

ABSTRACT Ethanol‐induced acute gastric mucosal injury (AGMI) remains a prevalent clinical problem, while current therapies are constrained by adverse effects and the immunogenicity of animal‐derived collagens. Here, we evaluate orally administered recombinant human type III colla...

SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

ABSTRACT Food allergies affect over 8% of children globally, with a 3.5‐fold increase in incidence in the past two decades. However, disease‐modifying therapies remain limited due to incomplete understanding of the underlying metabolic mechanisms. Thus, in this study, we aimed to...
