To assess the ecological risk of microplastics (MPs) in agricultural systems, it is critical to simultaneously focus on MP-mediated single-organism response and different trophic-level organism interaction. Herein, we placed earthworms soils contaminated with concentrations (0.02% 0.2% w/w) polyethylene (PE) polypropylene (PP) MPs investigate effect tomato against

Nanomaterials (NMs) have demonstrated enormous potential to improve agricultural production. Ten mg L–1 of customized manganese ferrite (MnFe2O4) NMs was selected as the optimal dose based on its outstanding effects promoting tomato flowering and After foliar application before flowering, MnFe2O4 increased leaf chlorophyll content by 20 percent, significantly upregulated expressions ferredoxin, PsaA, PsbA in leaves, likely serving an electron donor, leading a significant increase photosynthesis efficiency 13.3%. Long distance transport sucrose then confirmed upregulation transporter SUT1 SUT2 NM-treated leaves meristems. The genes associated with gibberellin biosynthesis, including GA20ox2, GA20ox3, SIGAST, induction gene SFT, were also upregulated. Importantly, time 13 days earlier over control. At reproductive stage, pollen activity ovule size, fruit number per plant, single weight, weight plant 50%, 30%, 75%, respectively. Metabolically, glucose-6-phosphate, phenylalanine, rutin, ascorbic acid (vitamin C), well decrease tomatine methionine, demonstrates nutritional value fruits. A verified companion field experiment showed 84.1% total production NM amendment. These findings provide support for early yield improvement nano-enabled systems.

Nanosilicon applications have been shown to increase plant defenses against both abiotic and biotic stresses. Silicon quantum nanodots (Si NDs), a form of nanosilicon, possess excellent biological physiochemical properties (e.g., minimal size, high water solubility, stability, biocompatibility), potentially making them more efficient in regulating responses stress than other forms silicon. However, date, we still lack mechanistic evidence for how soil-applied Si NDs alter the regulation physical chemical insect herbivores. To address this gap, compared effect fluorescent amine-functionalized (5 nm) conventional fertilizer sodium silicate on maize (Zea mays L.) oriental armyworm (Mythimna separata, Walker) caterpillars. We found that 50 mg/kg additions inhibited growth caterpillars most (35.7% 22.8%, respectively) as application doses (0, 10, 150 mg/kg). Both addition activated biosynthesis genes responsible (benzoxazinoids) (lignin) defense production. Moreover, upregulated gene expression antioxidant enzymes (SOD, CAT, POD) promoted metabolism (flavonoids) leaves under M. separata attack. Finally, show that, field conditions, ND increased cob weight (28.7%), grain (40.8%), 100-grain (26.5%) control, so silicon fertilizer. Altogether, our findings highlight potential be used an effective ecofriendly crop protection strategy agroecosystems.

AbstractDue to the frequent occurrence of extreme weather and severe environmental pollution, food security human survival are at risk. Silicon, a key element in plant nutrition remediation, has variety applications combatting various forms abiotic biotic stress fostering healthy plants soils. To establish silicon-based defense barrier for plants, we firstly summarized grouped mechanisms silicon functioning plants: 1) molecular regulation overall strengthening, 2) physical apoplastic obstruction, 3) energy conservation. Additionally, types materials as soil remediation fertilizers were discussed. Then, challenges build up such analyzed terms absorption transportation, deposition aggregation, perception regulation. An "external + internal" strategy was proposed accelerate establishment enhance plants' resistance including high temperatures, drought, ultraviolet radiation, salt, heavy metals, nutrient deficiencies, new pollutants, stress. Finally, this paper emphasized contribution Soil-Plant-Atmosphere system that eventually benefit health. This highlights current understanding future perspectives silicon-related research system, providing reference application agricultural fields.Keywords: pollutionplant healthSiliconsoil healthstress resistanceHandling Editors: Dan Tsang Lena Q.

Silicon (Si) is a widely recognized beneficial element in plants. With the emergence of nanotechnology agriculture, silicon nanoparticles (SiNPs) demonstrate promising applicability sustainable agriculture. Particularly, application SiNPs has proven to be high-efficiency and cost-effective strategy for protecting plant against various biotic abiotic stresses such as insect pests, pathogen diseases, metal stress, drought salt stress. To date, rapid progress been made unveiling multiple functions related mechanisms promoting sustainability agricultural production recent decade, while comprehensive summary still lacking. Here, review provides an up-to-date overview synthesis, uptake translocation, alleviating aiming reasonable usage nano-enabled The major points are listed following: (1) can synthesized by using physical, chemical, biological (green synthesis) approaches, green synthesis wastes raw materials more suitable large-scale recycling (2) translocation plants differs significantly from that Si, which determined factors properties SiNPs. (3) Under stressful conditions, regulate stress acclimation at morphological, physiological, molecular levels growth stimulator; well deliver pesticides regulating chemicals nanocarrier, thereby enhancing yield. (4) Several key issues deserve further investigation including effective approaches modification, basis SiNPs-induced resistance, systematic effects on ecosystem.

Plant diseases that affect crop production and productivity harm both quality quantity. To minimize loss due to disease, early detection is a prerequisite. Recently, different technologies have been developed for plant disease detection. Hyperspectral imaging (HSI) nondestructive method the of based on spatial spectral information images. Regarding detection, HSI can predict disease-induced biochemical physical changes in plants. Bacterial infections, such as Pseudomonas syringae pv. tabaci, are among most common areas soybean cultivation, implicated considerably reducing yield. Thus, this study, we used new analysis disease. We performed leaf reflectance with effect infected bacterial wildfire during growth stage. This study aimed classify accuracy leaves. Two varieties were experiment, Cheongja 3-ho Daechan, control (noninoculated) treatment (bacterial wildfire), respectively. inoculation was 18 days after planting, imagery data collected 24 h following inoculation. The signature revealed significant difference between diseased healthy leaves green near-infrared regions. two-way variance results obtained using Python package algorithm incidence two varieties, Daechan 3-ho, could be classified second third day inoculation, values 97.19% 95.69%, respectively, thus proving his useful technique Therefore, creating wide range research platforms various feasible.
