Winter Dietary Composition of Black Francolin (Francolinus francolinus) in Totali Public Game Reserve, Pakistan

The winter diet of Black Francolin (Francolinus francolinus) is poorly documented in Totali Public Game Reserve, Pakistan. We examined crop contents from 24 legally harvested birds (14 males and 10 females) collected during 2022–2024. Thirty-three identifiable food taxa were reco...

Genome-Wide Association Study of Body Measurement Traits at Birth in Cattle

Hexi cattle are an indigenous beef breed developed through multigenerational crossing of Simmental and Mongolian cattle, exhibiting exceptional adaptability to arid and semi-arid environments alongside robust growth performance. To investigate the genetic architecture underlying...

Aridity regulates scale-dependent effects of multiple resource additions on productivity stability in Eurasian grasslands

Increasing the supply of multiple limiting resources generally reduces biodiversity and community stability in grasslands. Aridity is known to modify biodiversity-stability relationships, yet it remains unclear whether the effects of multiple resource supply on biodiversity and s...

Effects of Relative Humidity on the Development, Survival, and Reproduction of Paralipsa gularis (Zeller) (Lepidoptera: Pyralidae), a Pest of Stored Grains and Maize

Paralipsa gularis (Zeller) (Lepidoptera: Pyralidae) is a storage pest native to Southeast Asia that has now become a major agricultural pest affecting maize during the late growth stage in the border regions of southern Yunnan, China, adjacent to Southeast Asia. The typical tropi...

Effects of Red and Blue Light on Steady-State and Dynamic Photosynthesis of Cucumber Seedlings

Our previous study revealed a significant effect of red and blue light on steady-state and dynamic photosynthesis in cucumber seedlings. To further investigate the mechanism by which red and blue light affect photosynthesis, cucumber (Cucumis sativus L. cv. Jinyou 365) seedlings...

Knockout of odourant receptor co-receptor HvarOrco compromises reproductive fitness in the ladybird Hippodamia variegata

Abstract The predatory ladybird, Hippodamia variegata , relies critically on olfaction for host location, oviposition site selection, and predator avoidance. Here, we employed CRISPR/Cas9-mediated genome editing to generate a stable, heritable odourant receptor co-receptor ( Orco...

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...

Porcine Reproductive and Respiratory Syndrome Virus: Adaptive Immunity, Immune Evasion and Emerging Strategies for Disease Control

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically important pathogens affecting the global swine industry. This review summarizes current knowledge of PRRSV-induced suppression of adaptive immune responses, with particular emphasis on imp...

Toward Iron-Biofortified Rice: Integrating BRUTUS-Family Regulation and Iron Chaperone Biology

Abstract Rice is both a leading model for cereal molecular genetics and one of the world’s most important staple foods, which makes it a decisive crop for iron (Fe) biofortification. However, the breeding goal is not simply to increase total plant Fe or even total grain Fe. For p...

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...

Developmental exposure to amitraz impairs reproductive development and metabolic homeostasis in honey bee (Apis mellifera) queens

Chemicals used within managed pollinator systems can become developmental stressors for non-target organisms, yet their effects on reproductively specialized individuals remain insufficiently understood. Here, we examined the developmental ecotoxicity of the in-hive acaricide ami...

Single-cell epigenomics in plants

Abstract Single-cell technologies enable epigenomics characterization at single-cell resolution, offering novel insights into gene expression regulation and a wide range of biological processes, including cell fate determination, developmental differentiation, and environmental a...

Integrated lncRNA and mRNA Transcriptome Analysis Reveals Candidate Regulatory Networks Associated with Postnatal Longissimus Dorsi Muscle Development in Hanper Sheep

Skeletal muscle development is a key determinant of meat production and meat-quality traits in sheep, but the coordinated long non-coding RNA (lncRNA) and messenger RNA (mRNA) co-expression landscape underlying postnatal muscle development in Hanper sheep remains unclear. In this...

Depth-dependent response functions and rainfall transition zones of soil-profile activation under varying antecedent moisture in the Shandian River Basin, northern China

Translating event rainfall into soil-profile wetting requires more than recording whether soil moisture increased; it requires estimating how activation response functions change with depth and antecedent moisture. We analyzed 955 rainfall site-events from 20 co-located rainfall...

SAMSN1 restricts Japanese encephalitis virus replication by recruiting TRIM21 to degrade viral proteins and activate the interferon pathway

Abstract Japanese encephalitis virus (JEV), a zoonotic mosquito-transmitted flavivirus, induces human encephalitis and swine reproductive diseases. No antiviral drugs or treatments exist for flavivirus infections, which cause severe symptoms. Even though some host proteins can su...

Dual-Edged Roles of Fungal Chlamydospores in Plant Protection: Research Progress and Application Potential

Chlamydospores are thick-walled, dormant propagules formed by fungi in response to environmental stress. They play contrasting roles in plant protection: serving as persistent inocula of soil-borne pathogenic fungi that contribute to recurrent disease outbreaks, while also acting...

Contagious caprine pleuropneumonia: a review and gap analysis of its impact, epidemiology, pathogenesis, and control

Contagious caprine pleuropneumonia (CCPP), caused by Mycoplasma capricolum subsp. capripneumoniae ( Mccp ), remains one of the most important small ruminant diseases and a major transboundary disease. Although primarily affecting goats, infections have also been reported in sheep...

Rhizosphere microbiome-dependent metabolic reprogramming enhances potato salt tolerance in saline soils

Soil salinization is increasing globally, causing yield losses, especially in irrigated agriculture. Rhizosphere microorganisms can improve plant salt tolerance, but evidence in potato remains limited. In this study, rhizosphere microbial community diversity and structure differe...
