Biochar mediated alleviation of cadmium stress in crop plants

-
  Biochar-mediated alleviation of cadmium stress in crop plants has emerged as an effective and sustainable strategy to improve plant health and productivity in contaminated soils. Biochar, a carbon-rich material derived from the pyrolysis of organic biomass, enhances soil physicochemical properties while immobilizing cadmium through adsorption, complexation, and precipitation mechanisms. Its high surface area, porous structure, and abundance of functional groups reduce cadmium bioavailability in the rhizosphere, thereby limiting metal uptake and translocation in crop plants. In addition, biochar application improves soil pH, cation exchange capacity, and nutrient retention, which collectively promote root growth and microbial activity. At the physiological level, biochar mitigates cadmium-induced oxidative stress by enhancing antioxidant enzyme activities, stabilizing membrane integrity, and improving photosynthetic efficiency. It also supports better water use efficiency and nutr...

Substantial amounts of soil organic carbon and macronutrients are stored in deep soil layers under bamboo plantations

-
  Substantial amounts of soil organic carbon and essential macronutrients are stored in deep soil layers under bamboo plantations, highlighting the hidden yet critical role of bamboo ecosystems in long-term soil fertility and carbon sequestration. Unlike many shallow-rooted vegetation systems, bamboo develops extensive and deep root–rhizome networks that actively transport organic matter and nutrients such as nitrogen, phosphorus, and potassium into subsoil horizons. These deep layers act as stable reservoirs, protecting carbon from rapid microbial decomposition and nutrient loss while enhancing soil structure, water-holding capacity, and ecosystem resilience. The accumulation of carbon and nutrients at depth not only supports sustained bamboo productivity but also strengthens the potential of bamboo plantations as nature-based solutions for climate change mitigation, sustainable land management, and restoration of degraded soils. #SoilOrganicCarbon #BambooPlantations #DeepSoilCar...

Microbial volatile organic compounds reshape plant hormonal networks and root herbivore defense

-
  Microbial volatile organic compounds (mVOCs) act as powerful airborne signals that reshape plant hormonal networks and enhance defense against root herbivores. Emitted by beneficial soil bacteria and fungi, these low-molecular-weight compounds can be perceived by plant roots and shoots, triggering complex hormonal crosstalk involving jasmonic acid, salicylic acid, ethylene, auxins, and abscisic acid. Through this hormonal reprogramming, mVOCs prime plants for faster and stronger defensive responses, including the activation of secondary metabolites, reinforcement of cell walls, and modulation of root architecture that limits herbivore feeding and performance. By fine-tuning growth–defense trade-offs without direct microbial contact, microbial volatiles represent an ecologically efficient strategy for belowground plant protection and highlight their potential application in sustainable pest management and climate-smart agriculture. #MicrobialVolatiles #PlantHormones #RootHerbivor...

Harnessing plant natural products for enhanced biotic stress resistance

-
  Harnessing plant natural products offers a sustainable and eco-friendly strategy to enhance biotic stress resistance in crops. Plants naturally produce a wide array of secondary metabolites—such as alkaloids, terpenoids, phenolics, flavonoids, and phytoalexins—that play crucial roles in defense against pathogens and herbivores. These compounds can directly inhibit the growth of fungi, bacteria, insects, and nematodes, or indirectly strengthen plant immunity by activating defense signaling pathways like salicylic acid, jasmonic acid, and ethylene networks. Advances in metabolomics, genomics, and synthetic biology have enabled the identification, optimization, and targeted application of these natural products through breeding, biostimulants, or bio-based pesticides. By reducing reliance on synthetic agrochemicals, harnessing plant-derived natural products not only improves crop resilience and yield stability but also supports environmental health and sustainable agricultural syste...

Multisource grassland evidence for plant functional traits in predicting soil biota biodiversity and functions

-
  Multisource grassland evidence shows that plant functional traits are powerful predictors of soil biota biodiversity and ecosystem functioning. By integrating field observations, trait databases, remote sensing, and experimental data across diverse grassland systems, studies reveal that traits such as specific leaf area, root depth, nutrient acquisition strategies, and litter quality strongly shape soil microbial and faunal communities. These plant traits influence the quantity and quality of carbon inputs, root exudation patterns, and microhabitat conditions, thereby regulating soil food web structure, microbial diversity, enzymatic activities, and nutrient cycling processes. The convergence of multiple data sources highlights consistent trait–biota–function linkages, emphasizing that plant functional composition, rather than species identity alone, governs belowground biodiversity and functions in grassland ecosystems under environmental change. #GrasslandEcosystems #PlantFunc...

Pesticide residues in ornamental plants marketed as bee friendly: Levels in flowers, leaves, roots and soil

-
  Pesticide residues have been widely detected in ornamental plants marketed as bee-friendly , raising concerns about unintended risks to pollinators. Analyses of flowers, leaves, roots, and associated potting soils reveal that multiple systemic and contact pesticides—particularly neonicotinoids, fungicides, and insect growth regulators—can persist across plant tissues. Flowers often contain residues at levels capable of exposing bees through nectar and pollen, while leaves and roots frequently show even higher concentrations due to systemic uptake and long-term accumulation. Soil and growing media act as reservoirs, enabling continuous transfer of pesticides into plant tissues even when foliar applications have ceased. These findings highlight a critical gap between “bee-friendly” labeling and actual chemical safety, emphasizing the need for stricter regulations, transparent labeling, and residue-free production practices to truly protect pollinators in urban and garden ecosystems...
