Special Issue Information

Dear Colleagues,

With the rapidly changing global climate, our agricultural systems are being confronted with more unpredictable and harsh environmental conditions than before, leading to compromised food production. Thus, to ensure safer and more sustainable crop production, the use of advanced nanotechnological approaches when it comes to plants is of great significance. In this Special Issue, our aim is to offer up-to-date scientific evidence and the potential for future research to improve our knowledge of the mechanisms that control the development of modern agriculture through advanced nanotechnology.

We warmly invite you and your colleagues to submit original research articles and reviews that address issues related to the recent advances in nanotechnology in agricultural systems that can assist to meet ever-growing demands of food sustainability. The application of nanotechnology can change traditional agricultural systems, allowing the target-specific delivery of biomolecules (such as nucleotides and proteins) and cater to the organized release of agrochemicals (such as pesticides and fertilizers). An amended comprehension of the communications between crops and nanoparticles (NPs) can improve the production of crops by enhancing tolerance toward environmental stresses and optimizing the utilization of nutrients. Additionally, approaches like nanoliposomes, nanoemulsions, edible coatings, and other kinds of NPs offer numerous methods in the post-harvest preservation of crops for minimizing food spoilage, thus establishing nanotechnology as a sustainable tool to improve modern agricultural practices. Submissions with a particular focus on an innovative and comprehensive approach to the topic or current unmet needs in strategies are particularly encouraged and appreciated.

Soil salinization poses a threat to the sustainability of agricultural production and has become a global issue. Cotton is an important cash crop and plays an important role in economic development. Salt stress has been harming the yield and quality of many crops, including cotton, for many years. In recent years, soil salinization has been increasing. It is crucial to study the mechanism of cotton salt tolerance and explore diversified materials and methods to alleviate the salt stress of cotton for the development of the cotton industry. Nanoparticles (NPs) are an effective means to alleviate salt stress. In this study, zinc oxide NPs (ZnO NPs) were sprayed on cotton leaves with the aim of investigating the intrinsic mechanism of NPs to alleviate salt stress in cotton. The results show that the foliar spraying of ZnO NPs significantly alleviated the negative effects of salt stress on hydroponic cotton seedlings, including the improvement of above-ground and root dry and fresh weight, leaf area, seedling height, and stem diameter. In addition, ZnO NPs can significantly improve the salt-induced oxidative stress by reducing the levels of MDA, H2O2, and O2− and increasing the activities of major antioxidant enzymes, such as superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT). Furthermore, RNA-seq showed that the foliar spraying of ZnO NPs could induce the expressions of CNGC, NHX2, AHA3, HAK17, and other genes, and reduce the expression of SKOR, combined with the CBL-CIPK pathway, which alleviated the toxic effect of excessive Na+ and reduced the loss of excessive K+ so that the Na+/K+ ratio was stabilized. In summary, our results indicate that the foliar application of ZnO NPs can alleviate high salt stress in cotton by adjusting the Na+/K+ ratio and regulating antioxidative ability. This provides a new strategy for alleviating the salt stress of cotton and other crops, which is conducive to the development of agriculture. Full article
