Selenium Alleviates Mercury Toxicity in Ophiocordyceps sinensis: Mechanistic Insights from Integrated Phenotypic and Transcriptomic Analyses

Ophiocordyceps sinensis, a valuable medicinal and nutritional resource, faces significant mercury (Hg) contamination risks. Total Hg content in some samples from key producing regions exceeds the 0.2 mg/kg limit set by the Chinese Pharmacopoeia, raising ecological and food safety...

Photoaging-driven amplification of polystyrene microplastic toxicity in wheat: physiological and multi-omics insights

Microplastics (MPs) in agroecosystems displayed phytotoxicity; however, the differential effects of pristine and photoaged MPs remain unclear. Herein, we examined the effects and mechanisms of polystyrene (PS) MPs on wheat ( Triticum aestivum L .) based on pristine and photoaged...

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...

Identification and functional analysis of transcription factor MhWRKY71-like from Malus halliana in response to low temperature

Late spring coldness and late frost during bud burst are major low-temperature disasters in apple production, which seriously hinder the sustainable development of the apple industry. WRKY transcription factors play central regulatory roles in plant responses to abiotic stresses....

Phenyl- O -β- d -ribofuranoside Derivatives from the Plant Endophytic Fungus Neofusicoccum sp. LZUC-S1 and Their Herbicidal Activity

Abstract Seven novel phenyl-O-β-d-ribofuranoside derivatives (1–7), along with four known naphthalenones (8–11), were isolated from the endophytic fungus Neofusicoccum sp. LZUC-S1 using a bioactivity-guided isolation. Their chemical structures were elucidated through an integrate...

Topological Reinforcement of Rhizosphere Microbial Networks Facilitates the Invasive Superiority of Spartina anglica

Rhizosphere microbial interaction patterns underpin the resilience and dominance of invasive plants in fluctuating coastal salt marshes. We compared the rhizosphere microbial communities of the invasive Spartina anglica and the native Spartina maritima across varying distances fr...

Integration of physiological and transcriptomic analyses unveils the drought resistance mechanism in Solanum tuberosum L.

Drought constitutes a significant limiting factor globally, impacting plant growth and development while constraining productivity, with its influence intensifying under global climate change. China’s primary potato-producing regions predominantly lie within arid and semi-arid zo...

Fulvic acid and hydrogen sulfide synergistically mitigate chromium stress in tobacco seedlings by regulating oxidative stress indicators and antioxidant defense mechanisms

Chromium (Cr) toxicity poses a significant threat to crop growth and agricultural productivity. Fulvic acid (FA) and hydrogen sulfide (HS) have emerged as promising agents for mitigating metal-induced toxicity; however, their combined effects on physiological and biochemical resp...

Mild deficit irrigation: A water-saving strategy for enhancing fruit quality and water production of wolfberry

Soil salinization, exacerbated by water scarcity in arid and semi-arid regions, represents a major constraint on the sustainable intensification of commercial wolfberry production. Appropriate irrigation management offers an approach to reducing water demand, mitigating salt stre...

Ammonium-Nitrate Ratio and Soil Moisture Jointly Regulate Early-Spring Nitrogen Acquisition Through Root Architectural Plasticity in Apple

Abstract Early-spring nitrogen (N) acquisition in perennial fruit trees represents a critical physiological bottleneck determining vegetative-reproductive balance, as remobilized woody-tissue N supports initial growth but excessive depletion compromises reproductive performance....

Proteomics- and Metabolomics-Based Investigation of the Effects of Astragalus membranaceus Powder on Meat Quality and Molecular Profiles of Longissimus dorsi Muscle in Ao-Hu Crossbred Rams

Astragalus membranaceus is a traditional Chinese medicinal herb commonly used as a feed additive in livestock production; however, the molecular mechanisms by which it influences meat quality in sheep remain poorly understood. In this study, 96 Ao-Hu crossbred rams were randomly...
