Development and Genomic Validation of a Population-Specific SNP Panel for Parentage Verification in Chinese Holstein Cattle

Accurate pedigree information is essential for genetic evaluation and genomic selection in dairy cattle. However, the performance of SNP-based parentage verification depends on marker informativeness, genomic distribution, and compatibility with the target population. In this stu...

Effects of Tillage Practices and Plastic Film Mulching on Soil Temperature, Dry Matter Production, and Yield Formation of Maize in a Cool Region

Limited thermal resources in the cool regions of Northeast China restrict maize growth and yield formation. A two-year field experiment was conducted in Dunhua, Jilin Province, China, during 2024–2025 using four tillage practices—deep rotary tillage (SX), deep harrowing (SB), dee...

Electron transport chain: a crucial target of luteolin in combating Trueperella pyogenes

ABSTRACT Trueperella pyogenes is an opportunistic pathogen capable of causing infections in both domestic and wild animals. Furthermore, the dissemination of resistance genes has resulted in varying degrees of antimicrobial resistance among T. pyogenes isolates. Therefore, it is...

Odorant Receptors Mediating Benzaldehyde Detection in Mythimna separata: Functional Identification and Ligand Selectivity

Benzaldehyde (BA) is a ubiquitous aromatic volatile produced by both plants and insects. In Mythimna separata, it also serves as a male-emitted pheromonal signal that mediates male–male competition by antagonizing the pheromone receptor MsepPR3 and disrupting the perception of th...

Searching for a Vanishing Fish: Development of an eDNA-Based Digital PCR Assay and Field Surveys for the Critically Endangered Chinese Bahaba

The critically endangered Chinese bahaba (Bahaba taipingensis) is difficult to monitor via conventional methods due to its low abundance and estuarine habitat. We developed a species-specific microfluidic digital PCR assay targeting the mitochondrial COI gene for environmental DN...

A Corn Ear Mass Prediction Method Based on TS-YOLO and Random Forest

Accurate estimation of corn ear mass is an essential component of intelligent harvesting. To achieve automated mass measurement of large-scale corn ears, this study developed a dual-view prediction platform and proposed a corn ear mass prediction method based on TS-YOLO and Rando...

Straw-to-biochar shift in alternate wetting and drying paddies: Unlocking carbon sequestration and net GWP reduction synergies

Straw return and straw-derived biochar amendment are widely used to enhance soil carbon sequestration and fertility. However, few studies have compared their effects on soil carbon sequestration and net global warming potential (GWP) in paddy fields under equivalent straw inputs,...

An ovary‐enriched lipase gene, LOC118266188 , is required for embryonic development and female fertility in Spodoptera frugiperda

Abstract BACKGROUND The regulatory functions of ovary‐enriched genes in female reproduction are well characterized in model insects, but remain largely unexplored in agricultural pests such as the fall armyworm (FAW), Spodoptera frugiperda . This study aimed to identify ovary‐enr...

Mass-Rearing of Insects on Food Waste to Produce Chitosan—A Bio-Based Plastic Alternative

Mass-rearing of insects is being promoted to meet demands for sustainable sources of livestock and pet feed, protein, oils, pharmaceutical precursors and more. Here, we describe an industrial symbiosis, in which insect mass-rearing is based on food waste, and chitin extracted fro...

Visual Perception and Autonomous Navigation Control for Orchard Robots: From Scene Understanding to Closed-Loop Motion Execution

Autonomous navigation is essential for orchard robots performing spraying, weeding, inspection, harvesting, and transport, yet semi-structured orchards combine repeatable tree-row geometry with canopy occlusion, uneven illumination, weak road boundaries, terrain variation, and in...

Comparative Analysis of Fatty Acid Composition in Skeletal Muscles and Serum of Tianfu Goats

Fatty acid composition contributes to the nutritional characteristics of goat meat, but its variation among anatomical muscles remains insufficiently characterized. This exploratory study determined fatty acid profiles in six skeletal muscles and serum from nine 10-month-old cast...

The influence of vapor pressure deficit changes on global terrestrial evapotranspiration

Abstract. Vapor pressure deficit (VPD) is increasingly recognized as the primary driver of uncertainty in future global evapotranspiration (E) trends. Accurately characterizing the spatiotemporal dynamics of VPD and clarifying its mechanisms of influence on terrestrial E are cruc...

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...

Chronic Nitrite Nitrogen Responses in Penaeus monodon: From Growth Phenotypes to Metabolic Hub Signaling

Nitrite nitrogen is a prevalent environmental stressor in intensive shrimp aquaculture that impairs growth and health, yet its chronic effects and underlying molecular mechanisms in Penaeus monodon remain incompletely understood. To address this, we exposed juvenile P. monodon (i...

Multi-objective optimization of subsurface drip fertigation for winter wheat in the North China Plain: balancing grain yield, resource use efficiency, and soil quality

Drip fertigation has been adopted to conserve water resources and improve water-nitrogen use efficiency. However, the optimal irrigation level and nitrogen application rate for drip-fertigated winter wheat in the North China Plain (NCP) are still unclear. To promote synergies amo...

Design and Performance Evaluation of a Blockchain-Based Agricultural Product Traceability System Using Hyperledger Fabric

Agricultural product safety incidents highlight trust deficits in supply chain management. This study designs and evaluates a Hyperledger Fabric-based agricultural traceability prototype in which public product data, enterprise farming details, and regulatory cost data are manage...

A helix-loop-helix gene orchestrates male fate in common carp

Fish show exceptional diversity in sex-determination mechanisms, making them a powerful system for studying how these pathways evolve. However, no definitive master sex-determining gene has yet been identified in Cyprinidae, a widely distributed and species-rich fish family. Here...

Growth and Metal Partitioning of the High-Biomass Grass Cultivar Minmu 6 Under Graded Cadmium and Lead Exposure

Phytoremediation requires plants that combine high biomass production with tolerance to metal stress. The responses of Pennisetum americanum (L.) Leeke × Pennisetum purpureum Schumach. ‘Minmu 6’ were evaluated in separate pot experiments with Cd at 0 (CK), 1.5 (L-Cd), 10 (M-Cd),...

Cover crop diversity generates complex rhizo-microbiome networks by improving soil properties

Agricultural soils face significant microbial disruption due to chemical inputs and continuous cropping. Cover crops offer a potential strategy to restore soil microbial health, yet the influence of cover crop species richness on root and rhizosphere microbiomes remains poorly un...
