Characteristics of microbial communities in the rhizosphere soil of potato (Solanum tuberosum L.) under different Cd contents in high-Cd geochemical background areas

Microorganisms play an important role in soil contamination remediation, yet the characteristics of soil microbial communities under different soil Cd concentrations in areas with a high-Cd geological background remain poorly understood. Here, we determined Cd content in low Cd p...

Identification and Expression Analysis of the CLE Gene Family in Sesame

The CLE (CLAVATA3/EMBRYO SURROUNDING REGION-related) small peptides constitute a large supergene family in plants and are extensively involved in plant stress responses and the regulation of growth and development. Light, water, gravity, and mechanical trauma play critical roles...

Tsukamurella tyrosinosolvens P9 enhances drought tolerance and recovery in peanut via regulation of stress resistance and rhizosphere microbiome

Plant growth-promoting rhizobacteria (PGPR) have been widely reported to enhance crop drought tolerance; however, mechanisms of rare actinomycetes across the drought-rewatering-maturation continuum in peanut remain unclear. Here, we investigated the effects of inoculation with Ts...

Ecological risk assessment of migratory bird feces in plateau wetland: Phosphorus speciation, ARGs, and pathogens

Plateau wetlands are critical habitats for migratory birds, but the potential ecological risks from the large-scale accumulation of migratory bird feces (MBF) remain poorly understood. This study focused on seven wintering waterbird species, including the Grus nigricollis , Grus...

Apolipoprotein D3 is required for long‐chain cuticular hydrocarbon accumulation and water retention in Acyrthosiphon pisum

BACKGROUND: The pea aphid, Acyrthosiphon pisum, is a damaging phloem-feeding pest of legume crops, and RNA interference (RNAi)-based targeting of stress-adaptation genes offers a promising route for target-specific pest management. Apolipoprotein D (ApoD) proteins are putative li...

Fabrication of Mg/Al-Layered Double Hydroxide–Biochar for Reducing Cadmium and Arsenic Uptake in Soil-Covered Morchella sextelata Cultivation

Cadmium and arsenic accumulation during soil-covered cultivation of Morchella sextelata limits its production in contaminated soils. Two Mg/Al-layered double hydroxide–biochar (LB) composites were prepared using grinding-assisted and coprecipitation procedures and denoted as LB1...

QTL mapping for spike length and candidate gene identification in wheat spike development (Triticum aestivum L.)

Spike length (SL) is a crucial factor influencing yield in wheat ( Triticum aestivum L.). In this study, a recombinant inbred line (RIL) population derived from the cross between Guixie 3 and Avocet S was utilized for genetic mapping of quantitative trait loci (QTL) controlling s...

Carbon Quantum Dots and Ectoine Foliar Application Enhance Heat Tolerance of Gentiana rhodantha

Heat stress exerts detrimental effects on the survival, growth, and productivity of Gentiana rhodantha Franch. ex Hemsl., a medicinal herb endemic to Southwestern China. The application of exogenous protective substances has been widely recognized as an effective and economical s...

Transcriptome profiling analysis of heat-adapted and heat-sensitive breeder hen jejunal mucosal tissues in response to acute heat stress

<title>Abstract</title> Background Heat stress impairs intestinal integrity in poultry, compromising nutrient digestion and absorption. Nevertheless, the individual variation in heat tolerance suggests distinct molecular responses that are still not well understood. Materials and...

Constructing co-assembly derived smart lipid nanoparticles for enhanced antimicrobial potency with plant growth-promoting potential

Lipid nanoparticles (LNP) are widely used in biomedical applications due to their biocompatibility and safety, yet their translation to plant systems remains limited. Here, we establish a unified strategy integrating antibacterial compound discovery, plant-adapted nanocarrier des...
