How do multidimensional land use conflicts shape rural multifunctionality? An empirical study of the Yangtze River Delta from a conflict–coordination perspective

In the context of urban–rural integration, how multidimensional land use conflict (LUC) differentially shapes rural multifunctionality is a key question for sustainable rural development. Existing studies, however, have largely treated the two independently, with limited systemat...

Acyl-CoA Oxidase-Mediated β-Oxidation Regulates the Lifestyle Transition of Metarhizium rileyi from Insect Pathogen to Plant Mutualist

Abstract Metarhizium rileyi as a widely distributed insect pathogenic fungus, has a promising application prospect in pest control. This study investigates M. rileyi strain XSBN200920 following its endophytic colonization of Nicotiana benthamiana. The fungus establishes systemic...

Enhanced antimicrobial activities of nicotine-enriched hydrothermal liquids from tobacco wastes

Hydrothermal carbonization (HTC) offers a promising pathway to convert alkaloid-rich tobacco wastes into functional carbon materials and bioactive liquids. However, the release behavior of nicotine during HTC and the relationship between nicotine occurrence and the antimicrobial...

Physiological regulation of flower bud differentiation in Bougainvillea under different drought stress intensities

Flowering in Bougainvillea is closely associated with plant water status; however, the optimal drought level for floral induction and the underlying physiological regulatory mechanisms remain unclear. In this study, Bougainvillea glabra ‘Mrs. Eva White’ was used to evaluate the e...

Coordination of cyclic electron flow and alternative electron sinks adjusts photosynthetic regulation in maize under fluctuating light during combined heat and drought stress

Field-grown maize is frequently exposed to fluctuating light (FL) combined with heat and drought during summer, yet the underlying photosynthetic regulatory mechanisms remain poorly understood. We examined chlorophyll fluorescence, the P700 redox state, and electrochromic shift s...

Establishment and application of a real-time fluorescence quantitative PCR assay for detecting EAPV in Passiflora edulis

East Asian Passiflora virus (EAPV) is a significant viral pathogen prevalent across passionfruit cultivation regions in China and causes substantial economic losses to the passionfruit industry. The development of a sensitive, rapid, and accurate diagnostic method is essential fo...

Genomic and phenotypic characterization of phosphate-solubilizing strain YNK-FB0058, which potentially represents a novel species within the genus Phyllobacterium

Phosphate-solubilizing bacteria are soil-dwelling probiotics that promote plant growth and convert unavailable phosphorus into absorbable forms for plants. A phosphate-solubilizing strain, YNK-FB0058, which potentially represents a novel species within the genus Phyllobacterium ,...

Prolonged Sublethal Imidacloprid Exposure Reduces the Functional Response and Searching Efficiency of Orius similis Against Frankliniella occidentalis

ABSTRACT Neonicotinoid residues can compromise biological control in integrated pest management, yet the role of exposure duration is rarely quantified for predatory bugs. Here, we compared short‐term (24 h) and long‐term sublethal exposure to imidacloprid (LC 10 and LC 20 ) on t...

Partner of bursicon Regulates Pheromone Gland Development and Sex Pheromone Biosynthesis in Helicoverpa armigera

Bursicon, a heterodimeric neuropeptide composed of Burs-α and its binding subunit Partner of bursicon (Pburs), is primarily known to regulate insect cuticle tanning and also participates in wing expansion, reproduction and immunity. Pburs is highly expressed during pheromone glan...

Molecular Characterization of a Novel Monopartite Begomovirus Infecting Weeds and Important Crops in Yunnan, China

The genus Begomovirus constitutes a group of devastating plant viruses causing significant economic losses in the production of agricultural crops. In the present study, conducted in Yunnan province, China, a novel monopartite begomovirus was identified from Bidens pilosa, Crasso...

Biostimulatory Effect of 3-Acetonyl-3-Hydroxyoxindole on the Growth and Secondary Metabolites of Khaya senegalensis: UPLC–MS/MS Profiling and Molecular Docking Insights

Developing sustainable agricultural biostimulants that simultaneously optimize vegetative growth and specialized metabolic pathways is critical for maximizing plant growth, photosynthetic efficiency, and metabolome reprogramming. In this study, for the first time, the effects of...

Genetic Diversity and Phylogeny of Chilli Veinal Mottle Virus in Yunnan Tobacco-Planting Regions Based on the CP Gene

Chilli veinal mottle virus (ChiVMV, Potyvirus capsivenamaculae) can infect various Solanaceae crops, causing a decrease in yield and quality. In recent years, ChiVMV has become one of the most prevalent viruses affecting tobacco production, but its diversity and genetic structure...

Genetic architecture of node-specific leaf length and candidate gene identification in maize revealed by a temperate–tropical multiparental population

Abstract Background Optimizing leaf morphology is essential for improving maize plant architecture, plant density tolerance, and yield. Leaf length is a key agronomic trait controlled by complex genetic mechanisms. In this study, upper leaf length (ULL), ear leaf length (ELL) and...

First Report of Leaf Rot on Chinese Chive ( Allium tuberosum Rottler ex Spreng.) Caused by Phytophthora heterospora in Yunnan Province, China

Chinese chives (Allium tuberosum Rottler ex Spreng.), an economically important aromatic vegetable, are widely cultivated worldwide. In May 2025, a severe leaf rot disease was observed on Chinese chives in Mile (24.45°N, 103.4°E), Yunnan Province, China. Following consecutive day...
