Mechanism and parameter optimization method for ordered vibration conveying of maize ears

Ordered conveying of maize ears is critical for non-destructive handling of seed samples in plant breeding. However, the traditional response surface methodology (RSM) struggles to fit the strongly nonlinear characteristics of this process, and the underlying mechanism of ordered...

Time-varying and nonlinear effects of climate policy uncertainty on air pollution and carbon emissions in China: combination of TVP-VAR and QQA

Climate policy uncertainty (CPU) can alter the predictability of mitigation pathways, yet its environmental benefits may differ across time horizons and transition stages for pollutants or carbon emissions. Because air pollutants and CO 2 are often co-emitted through fossil-fuel...

Unlocking the genetic potential of sugarcane: gene discovery for molecular breeding

Sugarcane is a globally important crop for sugar production and bioenergy generation. However, its highly complex allopolyploid genome has greatly hindered conventional breeding, making cultivar development a lengthy and labor-intensive process that often requires more than a dec...

Response of Soil Ammonia−Oxidizing Microorganisms to Biochar Amendment Under Continuous Cropping and Crop Rotation Systems

Ammonia−oxidizing archaea (AOA), ammonia−oxidizing bacteria (AOB), and Comammox are key drivers of soil nitrification and play crucial roles in soil nitrogen cycling, with distinct functional contributions. AOA and AOB primarily drive the first step of nitrification by oxidizing...

Design and implementation of sheep posture estimation algorithm based on skeletal keypoint localization

Automated sheep posture recognition can provide posture-related behavioural information for precision livestock monitoring. Manual video observation is labour-intensive, and contact sensor-based methods may require specialized installation. This study developed a non-contact shee...

Baseflow dominates river flow during droughts across the global streamflow network

Hydrological droughts occur when rainfall shortages reduce water storage in catchments, leading to delayed and prolonged low-flow conditions. How strongly baseflow supports river flow during droughts and whether this buffering remains stable under climate warming remain uncertain...

Spatiotemporal dynamics of China’s cropland carbon budget from 2000 to 2020: incorporating harvested carbon and straw return

Agroecosystems play a crucial role in regulating the terrestrial carbon cycle, especially in China where there are about 128 million hectares of cropland, accounting for about 10% of the global cropland area. Previous regional-scale studies have primarily used net ecosystem produ...

N-enriched biochar with an optimized C:N ratio enhances crop growth by regulating enzymatic activities, soil properties, and photosynthetic efficiency under varying N fertilization

Biochar is widely used to enhance soil fertility and productivity, but the role of its C:N ratio and its interaction with varying nitrogen (N) application rates remains poorly understood. This study evaluated the effects of N-enriched biochar (NB) with different carbon-to-nitroge...

Life History Traits of Mythimana loreyi (Lepidoptera: Noctuidae) on Two Transformation Events (DBN9936 and Ruifeng 125)

Mythimna (=Leucania) loreyi (Lepidoptera: Noctuidae) is an important pest of summer maize (Zea mays) in China’s Huang–Huai–Hai region. The approved transformation events DBN9936 (Cry1Ab) and Ruifeng 125 (Cry1Ab/Cry2Aj) were primarily developed to target Ostrinia furnacalis, and 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...

Effects of body size, temperature, and salinity on survival and growth of Oncorhynchus mykiss during salinity acclimation

This study investigated the individual and interactive effects of body size, water temperature, and ambient salinity on survival and weight gain of Oncorhynchus mykiss during salinity acclimation using a three-factor, three-level orthogonal design to identify optimal acclimation...

A decision-making method for light regulation of cucumber seedlings considering changes of temperature and CO2 in protected agriculture

Light serves as the primary energy source for photosynthesis and significantly influences plant morphology and biomass accumulation. In protected agricultural systems, light environment parameters (intensity and spectral quality) critically determine crop productivity. A data-dri...

Elucidating flavor formation molecular mechanisms in peanut roasting through multi-omics analysis

Oilseeds are an important global agricultural resource, as one of the world’s three major oilseed crops, peanuts ( Arachis hypogaea L .) exhibit a complex flavor formation process during roasting, which remains poorly understood. The molecular pathways and interactions underlying...

Effects of Different Light Spectra on Growth Performance, Body Coloration, and Pigmentation-Related Gene Expression in Koi Carp (Cyprinus carpio var. koi)

Light is a critical environmental factor in aquaculture, directly or indirectly regulating the growth, reproduction, body coloration, and biological rhythms of cultured animals. However, in koi farming, spectral composition is often overlooked or arbitrarily selected. This study...

Arachidonic Acid Enhances Reproductive Performance and Oocyte Quality of Female Blotched Snakehead (Channa maculata) via Activation of the TGF-β/Smad Signaling Pathway

Arachidonic acid (ARA) is an indispensable fatty acid for aquatic organisms, playing critical roles in reproductive physiology. This study aimed to evaluate the effects of graded dietary ARA levels on the reproductive performance, tissue fatty acid profiles, plasma sex hormone an...

Common-Garden Transcriptomes Distinguish Leaf-Form-Associated from Site-Associated Expression in Zygophyllum xanthoxylum

Zygophyllum xanthoxylum (Bunge) Maxim. is a dominant, deep-rooted shrub of the temperate deserts of north-western China whose leaflets range from comparatively flat and broad to slender and terete, but the molecular basis of this variation has rarely been reported. We compared th...
