Genome-Wide Marker–Trait Analysis of Agronomic and Biomass-Related Traits in an Interspecific Miscanthus F1 Population Grown on Reclaimed Mine Land

Miscanthus is a perennial bioenergy crop suited to marginal and degraded land, yet relatively little is known about the genetic basis of biomass-related variation in interspecific hybrids across years. We evaluated 100 F1 genotypes from Miscanthus sacchariflorus × M. lutarioripar...

Manganese Dioxide Modified Low-Temperature Pyrolytic Carbon Rich in Oxygen-Containing Functional Groups for Efficient Vanadium Ion Adsorption

Vanadium-bearing wastewater threatens aquatic ecosystems and human health, calling for efficient, low-cost adsorbents. In this study, low-temperature pyrolytic carbon rich in oxygen-containing functional groups is prepared from Camellia oleifera fruit shells (COS) and modified wi...

Dihydromyricetin Alleviates Reserpine-Induced Depression by Modulating the Microbiota–Gut–Brain Axis

Abstract Dihydromyricetin (DMY) is a natural flavonoid with neuroprotective and antidepressant potential, but its role in the microbiota–gut–brain axis remains unclear. Using a reserpine-induced depression rat model, we integrated behavioral, inflammatory, histological, microbiot...

Genome-wide association analyses reveal genetic loci associated with cold responses in Miscanthus under non-acclimated and cold-acclimated conditions

Miscanthus species are C4 perennial bioenergy crops with broad environmental adaptability, yet episodic freezing events can constrain establishment and productivity. We evaluated cold-response variation in a 144-accession panel comprising 73 M. sacchariflorus and 71 M. lutariorip...

Variable-Dimension Differential Evolution for Ring-Count-Optimized Sparse Concentric Ring Array Synthesis

This communication proposes a variable-dimension differential evolution (VDDE) algorithm for synthesizing uniform amplitude sparse concentric ring arrays (CRAs) with minimized peak sidelobe level (PSL). Different from conventional fixed-ring-count methods, the VDDE simultaneously...

Tungsten in Agricultural Soil Triggers Coordinated Bioenergetic Responses and Gut Microbiome Dysbiosis in Earthworms: Implications for Agricultural Soil Health

Abstract Tungsten (W) can accumulate in agricultural soils near mining, smelting, industrial, and waste-disposal sites, yet its chronic effects on beneficial soil fauna remain poorly understood. Eisenia fetida were exposed for 28 d to soil W concentrations selected with reference...

Multi-Stage Transcriptomics Reveals TF- and lncRNA-Mediated Regulatory Networks Governing Glyphosate Resistance in Cyperus rotundus

Abstract Glyphosate resistance in Cyperus rotundus, a globally invasive weed, is increasingly threatening crop production, yet its molecular mechanisms remain unclear. Here, we performed multi-stage RNA sequencing of tubers from glyphosate-resistant and -susceptible populations a...

Extracellular Vesicle‐Encapsulated Small RNAs From Clostridium Butyricum Modulate Host Intestinal Lipid Metabolism

ABSTRACT The gut microbiota plays a critical role in regulating intestinal lipid metabolism, yet the mechanisms governing microbiota–host interactions during lipid uptake remain unclear. Here, we examined the relationship between fat digestibility and gut microbial composition, a...

Causal inference maps the sex-dimorphic genetic architecture and inflammatory-metabolic networks underpinning perceived aging in UK Biobank

Self-perceived facial aging is an externally observable aging-related phenotype that may reflect both biological and psychosocial dimensions of aging. However, its genetic and molecular determinants, sex-specific heterogeneity, and relationship with systemic aging-related pathway...

Pleiotropic effects of arnT deletion on colistin resistance, virulence, and stress tolerance in Aeromonas hydrophila are associated with impaired outer membrane homeostasis

Aeromonas hydrophila is a widespread zoonotic and aquatic pathogen posing growing challenges in aquaculture and public health due to increasing antimicrobial resistance and virulence. The arnT gene has been regarded primarily as a mediator of colistin resistance via lipopolysacch...

Comparative analysis of taste profiles and metabolic characteristics in white tea processed from wild and cultivated tea plants

Abstract BACKGROUND Wild tea trees represent valuable germplasm resources, with distinctive chemical characteristics and environmental resilience, but the biochemical basis underlying their flavor characteristics and potential contribution to white tea quality remain poorly under...

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...

Recombinant humoral immune proteins differentially modulated Cry1Ac susceptibility in Plutella xylostella

The insect immune system is closely associated with Bt resistance. Our previous studies have shown that silencing humoral immune genes (PxPGRP2, PxIMD, PxSPN1 and PxPPO1) in Plutella xylostella significantly affected larval susceptibility to Cry1Ac and also impacts fecundity. How...

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

ABSTRACT The proliferation of antibiotic resistance genes (ARGs) in aquaculture ecosystems poses substantial ecological and public health risks. This study conducted a cross‐provincial investigation of intestinal ARG profiles in American bullfrogs ( Aquarana catesbeiana ) from se...

Microbiota Structure and Functional Variation Across Intestinal Segments of Spinibarbus caldwelli

Spinibarbus caldwelli is an important commercial aquaculture species in China. To investigate gut microbiota composition, inter-species interactions, and their correlation with intestinal function across different gut segments, we analyzed 18 gut samples from six wild S. caldwell...

Assessing the contribution of nuclear energy to the ecological footprint in China: the role of natural resource consumption and agricultural productivity dynamics

China’s rapidly expanding ecological footprint poses a critical threat to environmental sustainability. Yet the combined roles of natural resource use, nuclear energy, and agricultural inputs in driving this footprint remain insufficiently explored within a unified analytical fra...

Design and Optimization of a Vibratory Device for Embryo-Oriented Single-Row Conveying of Rice Seeds
