Abstract With the rapidly changing global climate, agricultural systems are confronted with more unpredictable and harsh environmental conditions than before which lead to compromised food production. Thus, ensure safer sustainable crop production, use of advanced nanotechnological approaches in plants (phytonanotechnology) is great significance. In this review, we summarize recent advances phytonanotechnology that can assist meet ever-growing demands sustainability. The application change traditional systems, allowing target-specific delivery biomolecules (such as nucleotides proteins) cater organized release agrochemicals pesticides fertilizers). An amended comprehension communications between crops nanoparticles (NPs) improve production by enhancing tolerance towards stresses optimizing utilization nutrients. Besides, like nanoliposomes, nanoemulsions, edible coatings, other kinds NPs offer numerous selections postharvest preservation for minimizing spoilage thus establishing phtonanotechnology a tool architect modern practices.

Abstract Background Salinity is a big threat to agriculture by limiting crop production. Nanopriming (seed priming with nanomaterials) an emerged approach improve plant stress tolerance; however, our knowledge about the underlying mechanisms limited. Results Herein, we used cerium oxide nanoparticles (nanoceria) prime rapeseeds and investigated possible behind nanoceria improved rapeseed salt tolerance. We synthesized characterized polyacrylic acid coated (PNC, 8.5 ± 0.2 nm, −43.3 6.3 mV) monitored its distribution in different tissues of seed during imbibition period (1, 3, 8 h priming). Our results showed that compared no nanoparticle control, PNC nanopriming germination rate (12%) biomass (41%) ( Brassica napus ) under (200 mM NaCl). During hours, were located mostly coat, nevertheless intensity cotyledon radicle was increased alongside increase hours. amount absorbed water (52%, 14%, 12% at 1, priming, respectively) activities α-amylase significantly higher (175%, 309%, 295% treatment than control. primed lower content MDA, H 2 O , • − both shoot root control stress. Also, stress, enabled K + retention (29%) Na accumulation (18.5%) /K ratio (37%) Conclusions suggested besides more activities, improves tolerance through alleviating oxidative damage maintaining ratio.

Abstract Background Heavy metals repress tobacco growth and quality, engineered nanomaterials have been used for sustainable agriculture. However, the underlying mechanism of nanoparticle-mediated cadmium (Cd) toxicity in remains elusive. Results Herein, we investigated effects Fe 3 O 4 ZnO nanoparticles (NPs) on Cd stress cultivar ‘Yunyan 87’ ( Nicotiana tabacum ). severely repressed growth, whereas foliar spraying with NPs promoted plant as indicated by enhancing height, root length, shoot fresh weight under toxicity. Moreover, increased, including Zn, K Mn contents, roots and/or leaves facilitated seedling stress. Metabolomics analysis showed that 150 76 metabolites were differentially accumulated stress, respectively. These significantly enriched biosynthesis amino acids, nicotinate nicotinamide metabolism, arginine proline flavone flavonol biosynthesis. Interestingly, restored 50% 47% roots, while they 70% 63% to normal levels, thereby facilitating growth. Correlation further these metabolites, proline, 6-hydroxynicotinic acid, farrerol quercetin-3- -sophoroside, correlated Conclusions results collectively indicate metal can serve regulators provide insights into using them improving crops heavy metal-contaminated areas.

The use of nanotechnology has emerged in the agricultural sector. In recent years, several nano-enabled materials have been reported for weed control. Nano-enabled herbicides (also called nanoherbicides) can be designed from organic, inorganic, or hybrid materials. These unique properties such as small size, specific surface area, and ability to control release metal ions organic molecules field. Some studies nanoherbicides provide better management compared non-nanoformulations. However, regarding environmental risk assessment mechanisms action plants are still incipient. Nevertheless, they essential ensure a safe application human health environment. this review, we outlined current understanding well some strategic design fabricate nanostructures Also, critical discussion fate, behavior effects was addressed order achieve products environmentally friendly sustainable agriculture.

Salinity is a global issue limiting efficient agricultural production. Nano-enabled plant salt tolerance hot topic. However, the role of nanoparticles induced possible early stimulation on antioxidant system in its improved still largely unknown. Here, poly (acrylic) acid coated nanoceria (cerium oxide nanoparticles) (PNC, 7.8 nm, -31 mV) with potent ROS (reactive oxygen species) scavenging ability are used. Compared control, no significant difference H2O2 and O2•─ content, MDA (malondialdehyde) relative electric conductivity, Fv/Fm was found leaves and/or roots cucumber before onset salinity stress, regardless leaf or root application PNC. While, compared activities SOD (superoxide dismutase, up to 1.8 folds change), POD (peroxidase, 2.5 change) CAT (catalase, 2.3 content GSH (glutathione, 3.0 ASA (ascorbic acid, 2.4 PNC spray were significantly increased. RNA seq analysis further confirmed that foliar upregulates more genes over than application. These results showed sprayed have stronger effect applied one sensitive root. After plants better improvement one. Also, higher whole cerium after stress. In summary, we optimal terms improving tolerance, this associated plants.
