OSAIN: An Ontology-Guided Sparse Additive-Interaction Network for Interpretable Multi-Horizon Forecasting of Diamondback Moth (Plutella xylostella) Abundance

Forecasting diamondback moth (Plutella xylostella) abundance months ahead could support timely crop protection, but short monitoring records challenge both accuracy and interpretability. We examined whether ecological structure could improve multi-horizon forecasts while making t...

Lateral flow immunoassay for highly sensitive antibody detection of Clostridium perfringens ε toxin

ε-toxin, secreted by Clostridium perfringens , causes severe enterotoxemia in sheep and goats, resulting in substantial economic losses in the small ruminant industry. Monitoring ε-toxin-specific antibody levels is essential for early disease surveillance, vaccine-induced immunit...

Biochar–Straw Interaction Drives Soil Carbon Accrual by Modulating Microbial Metabolic Pathways

Abstract Straw and biochar additions can enhance long-term carbon storage, yet how their interactions regulate carbon mineralization and allocation remains unclear. We conducted a 360-day microcosm incubation employing a reciprocal 13C-labeling design that paired 13C-labeled stra...

Motion sickness incidence estimation incorporating back-measured torso biodynamic response: Modeling and real-vehicle evaluation

Accurate estimation of motion sickness incidence (MSI) is important for vehicle comfort optimization and motion-sickness mitigation. Conventional vibration-based functional models generally use vehicle acceleration directly and therefore do not account for mechanical transmission...

Auditory–Olfactory Integration in Simulated Natural Environments Dissociates Neural and Subjective Responses in Visually Impaired Individuals

Visually impaired individuals rely on cross-modal plasticity to compensate for absent visual input, yet the neurophysiological mechanisms underlying naturalistic auditory–olfactory integration remain poorly characterized. This study investigated how combined auditory and olfactor...

Size‐Resolved Particle Effective Density in the Free Troposphere at Mt. Hua, China: Influence of Chemical Aging and Sources

Abstract Effective density ( ρ eff ) is a key physical property of atmospheric particles, yet it has rarely been investigated in free tropospheric environments. It is largely determined by chemical compositions and particle morphology, providing valuable insights into atmospheric...

Single-Cell Insights into Virus–Microbe Interactions in Emerging Contaminant Degradation

Abstract Viruses are increasingly recognized as critical regulators of microbial ecology, yet their roles in pollutant degradation remain largely unexplored. Here, we integrate Raman-activated cell sorting–stable isotope probing (RACS-SIP) and single-cell genomics to elucidate vi...

Environmental Occurrence, Toxicity Concerns, Degradation Behavior, and Plant Resistance of Glufosinate-Ammonium

The market for traditional non-selective herbicides has undergone dramatic changes over the past decade. As an emerging herbicide, glufosinate-ammonium’s market share has been steadily increasing. However, with its widespread use, glufosinate-ammonium residues have been detected...

Robust slip-ratio regulation for agricultural tractors with transformer-enhanced speed estimation

In heavy-draft field operations such as plowing, spatially varying soil properties and traction-load fluctuations can cause excessive tractor wheel slip, complicating longitudinal-speed estimation and slip-ratio regulation. To address this issue, this study proposes a robust slip...

The laccase gene CcLac2 is essential for the summer‐form to winter‐form transition in the Chinese pear psyllid

Abstract BACKGROUND The Chinese pear psyllid ( Cacopsylla chinensis ), a vector of the bacterial pathogen Erwinia amylovora , displays seasonal polyohenism, transitioning from a summer‐form to a winter‐form in response to temperature fluctuations. Although the winter‐form phenoty...

Plant growth regulator diethyl aminoethyl hexanoate suppresses Aspergillus flavus growth and aflatoxin biosynthesis through disruption of redox homeostasis

ABSTRACT Aflatoxin B₁ (AFB₁), produced by Aspergillus flavus , is a major threat to food safety and human health. In this study, we report that diethyl aminoethyl hexanoate (DA-6), a plant growth regulator, exhibits strong antifungal and anti-aflatoxigenic activities against A. f...

The LrAN2-LrSOS3 regulatory module enhances salt tolerance and anthocyanin accumulation in Lycium ruthenicum

Abiotic stress-induced anthocyanin accumulation enhances stress tolerance and improves the quality of fruits, vegetables, and other horticultural crops. The promising natural blue colorant petanin, mainly derived from the wild resource of Lycium ruthenicum fruit, has attracted co...

Evaluation of Ornamental Traits and Their Associations with Genomic Simple Sequence Repeat Markers in Globba sherwoodiana

Globba spp. is a perennial herbaceous plant of the Zingiberaceae family, characterized by its unique floral architecture and diverse coloration with high ornamental and medicinal value. However, research on the genetic basis of Globba is still insufficient, and only a limited num...

Cytological and Transcriptomic Profiling Reveals the Developmental Basis of Stem Diameter Variation in Luffa

Stem diameter is an important agronomic trait determining plant architecture, lodging resistance and yield formation, yet its cytological and molecular mechanisms in the major cucurbit crop Luffa remain largely unclear. Herein, two Luffa inbred lines, S1174 (Luffa acutangula, thi...

Genome-Wide Analysis of the Longan HB/HD-ZIP Gene Family and Heterologous Functional Analysis of DlHB22 Associated with Fruit Energy Metabolism

The HB (homeobox) transcription factor family plays important roles in plant growth, development, morphogenesis, and stress responses; however, its involvement in longan (Dimocarpus longan Lour.) fruit energy metabolism remains unclear. In this study, 32 DlHB family members were...

Volatilomic and transcriptomic analyses uncover the mechanisms underlying flavor-related VOC changes during the harvest period of Citrus reticulata ‘Chachi’

Harvest timing is a critical determinant of the quality of Citrus reticulata ‘Chachi’ (CRC), the sole raw material for Guang Chenpi. However, the molecular mechanisms underlying the dynamics of flavor-related volatile organic compounds (VOCs) across the commercial harvest period...

Metabolic profiling reveals spatially-distinct reprogramming of host central carbon metabolism during Trichinella spiralis infection

The metabolic interplay between Trichinella spiralis (Ts) and its host remains a critical but underexplored aspect of trichinosis pathogenesis. Understanding how the parasite manipulates host metabolism is key to developing new diagnostic and therapeutic strategies. We employed t...

Identification of reference genes for real-time quantitative PCR in different development stage in chili pepper fruits(Capsicum annuum and Capsicum chinense)

Abstract The selection of appropriate reference genes is a fundamental prerequisite for reliable gene expression analysis using real-time quantitative polymerase chain reaction (RT-qPCR). To date, no systematic study has identified reference genes for normalizing RT-qPCR data in...

From Cotton to Wheat–Maize: Farmer Decision-Making and Cropping Structure Transformation in a Smallholder County of China

Adjusting cropping structure is a key way smallholder agriculture adapts to changing labor availability, production costs, mechanization, and agricultural services. Most studies explain such change through macro-level factors—prices, policies, and resource endowments—and pay less...

Spinetoram‐based seed‐pelleting with synergistic mixtures enhances control of the diamondback moth

BACKGROUND: The diamondback moth, Plutella xylostella, is one of the most destructive pests of cruciferous crops worldwide. Its high fecundity, stress tolerance and seasonal migration often render traditional spray control ineffective. In this study, we propose an alternative met...
