Article
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 and physiochemical properties (e.g., minimal size, high water solubility, stability, and biocompatibility), potentially making them more efficient in reg...
Article
A multifunctional nanomaterials-based agrochemical delivery system could supply a powerful tool for the efficient use of pesticides. Redox-responsive carriers as novel delivery systems of pesticide application in agriculture could promote the pest control and reduce plant pesticide residues due to the controllable release of agrochemicals. Herein,...
Article
To promote the sustainable and safe application of nanotechnology employing engineered nanoparticles (NPs) in agroecosystems, it is crucial to pay more attention to the NP-mediated biological response process and environmental impact assessment simultaneously. Herein, 50 mg kg-1 La2O3 NPs were added to soils without and with earthworms for cherry r...
Article
Chitosan, as a natural non-toxic biomaterial, has been demonstrated to enhance plant defense against oxidative stress. However, the general pattern and mechanism of how chitosan application modifies the amelioration of oxidative stress in plants have not been elucidated yet. Herein, we performed a meta-analysis of 58 published articles up to Januar...
Article
The exposure risk of nano-enabled products towards plants and related food safety has attracted great attention. Here, particle concentrations and the size distribution of nanoparticles (NPs) in five plants (rice, maize, cucumber, amaranth and kidney bean) after foliar exposure to CeO2, La2O3, Fe3O4, and MnFe2O4 NPs at a concentration of 10 mg L⁻¹...
Article
In this study, Bright Yellow 2 (BY-2) tobacco (Nicotiana tabacum L.) cell suspensions exposed to manganese ferrite nanoparticles (nMnFe2O4) or nitrogen-doped carbon dots (N-CDs) were analyzed for hormonal pathways. The dose response trial (0.05-1 mg L⁻¹, 2-72 h) showed that N-CDs (2.9 ± 0.5 nm) at 0.1 mg L⁻¹ and nMnFe2O4 (28.7 ± 7.7 nm) at 1 mg L⁻¹...
Article
Alleviating the adverse effects of abiotic and biotic stress factors on crop plants is essential to achieve higher productivity for satisfying the future food demands of the rapidly-growing global human population. The application of Si nanomaterials (Si NMs) could be an ecologically-sound alternative, as there is evidence that Si NMs could positiv...
Article
Nanoplastics (NPs) are widely detected in aquatic ecosystems and attracting considerable attention. Although ecotoxicological impacts of NPs on aquatic biota are increasingly identified, the extent and magnitude of these detrimental effects on fish and aquatic invertebrates still lack systematic quantification and mechanistic interpretation. Here,...
Article
Silicon, in its nanoscale form, has shown plant-promoting and insecticidal properties. To date, however, we lack mechanistic evidence for how nanoscale silicon influences the regulation of plant chemical defenses against herbivore attacks. To address this gap, we compared the effect of Si nanodots and sodium silicate, a conventional silicate fertil...
Article
Improving plant resistance against various environmental stresses is crucial to gain higher agricultural productivity for meeting future food demands of the fast-growing global population. Nanozymes, nanomaterials (NMs) with enzyme-like activity, have shown the potential to defend environmental stresses via scavenging reactive oxygen species (ROS)...
Article
The use of engineered nanomaterials (NMs) for agricultural applications is becoming increasingly interesting because NMs have been shown to promote crop yield, and also to some extent, protection against insect...

Entomopathogenic nematodes (EPNs) have been extensively studied as potential biological control agents against root-feeding crop pests. Maize roots under rootworm attack have been shown to release volatile organic compounds, such as (E)-β-caryophyllene (Eβc) that guide EPNs toward the damaging larvae. As yet, it is unknown how belowground ecosystem...
Article
The molecular and physiological mechanisms of how rare earth oxide nanoparticles (NPs) alter radish (Raphanus sativus L.) taproot formation and cracking were investigated in the present study. We compared plants that received suspensions of 10, 50, 100, 300 mg L⁻¹ of La2O3 NPs, 300 m L⁻¹ La2O3 bulk-particles (BPs), 0.8 m L⁻¹ La³⁺, or only water for...

Two greenhouse experiments using soils from long-term field plots were carried out to test whether and how soil factors modulated by organic amendments feed back to rice plant growth and defense against an aboveground herbivore, the planthopper Nilaparvata lugens. Using factorial combinations of sterilized soil and soil inocula obtained from chemic...

Pollution of toxic heavy-metal ions such as mercury ions (Hg²⁺) is well known to severely threaten ecological environment and human health. Correspondingly, development of a fast and sensitive method for detecting heavy-metal ions is urgently needed and has been received widespread attention in recent years. In this study, carbon nanodots (CDs) wit...
Article
Nitrogen (N) cycling by soil microbes can be estimated by quantifying the abundance of microbial functional genes (MFG) involved in N-transformation processes. In agro-ecosystems, biochars are regularly applied for increasing soil fertility and stability. In turn, it has been shown that biochar amendment can alter soil N cycling by altering MFG abu...
Article
The growing application of nanotechnology causes the release of engineered nanoparticles (NPs) into the aquatic environment. With increasing concerns on the potential effect of NPs to the aquatic organisms, investigations on NPs toxicity to algae are rising. To date, the overall algal responses to cope with NPs toxicity are still uncertain. In this...
Article
How plants cope with herbivore attack is partially modulated by the biotic and abiotic environment where the plant lives. For instance, theory predicts that soil fertility should drive patterns of plant resource allocation and defensive strategies. Earthworms, by their burrowing and casting activities, modify soil physicochemical properties and soi...
Article
The increasing occurrence of engineered nanoparticles (NPs) in soils may decrease water uptake in crops, followed by lower crop yield and quality. As one of the most common rare earth oxide NPs, lanthanum oxide (La2O3) NPs may inhibit the relative expressions of aquaporin genes, thus reduce water uptake. In the present study, maize plants were expo...
Article
Full-text available
Subterranean detritivores such as earthworms can increase soil nutrient availability through their burrowing and casting activities. A number of recent studies have explored whether these changes caused by earthworms may in turn affect plant performance and resistance to herbivores, but no formal synthesis of this literature has been conducted to d...

Sustainable agriculture is certainly one of the most important challenges at present, considering both human population demography and evidence showing that crop productivity based on chemical control is plateauing. While the environmental and health threats of conventional agriculture are increasing, ecological research is offering promising solut...
