摘要:

盐分是威胁全球粮食安全的重大问题。在各种不同的策略中,纳米技术在非生物逆境下,如盐胁迫下的作物生产中显示出巨大潜力。在本综述中,我们讨论了与纳米材料应用的不同方法相关的环境挑战,包括种子纳米引发、叶面和土壤/根系施用。基于先前的研究,纳米引发使用较少的纳米材料,对环境安全和食物链的影响较小。我们基于纳米材料在农业上的安全、可持续利用的应用方法,详细讨论了预防措施。此外,还总结了抗氧化酶触发纳米材料和直接清除活性氧(ROS)的纳米材料(纳米酶)在植物耐盐性中的作用。纳米材料通过各种解剖、生理和分子机制改善钠(Na+)和钾(K+)的稳态,从而提高植物的耐盐性。然而,纳米材料在调节植物光合作用和激素平衡方面的作用在很大程度上被忽视。我们明确了当前的研究空白,并为今后的研究工作提供了指导。本综述旨在为研究者在利用纳米颗粒进行植物抗逆性研究时,更好地理解纳米颗粒和不同植物相关因子的合理设计提供指导。这将有助于提高纳米颗粒进入植物体内的递送效率。此外,在获得足够的科学知识和更好的理解之后,纳米颗粒可以成为可持续农业的组成部分,节约成本,减少生物安全问题和环境污染。

Abstract:

Salinity is a major issue threatening global food security.  Among the different strategies, nanotechnology has shown tremendous potential for improving crop production under abiotic stresses such as salinity.  In this review, we discuss the environmental challenges associated with the different methods of nanomaterial application, including seed nanopriming, as well as foliar and soil/root application.  Based on previous research, nanopriming uses less nanomaterials and has minimal concerns regarding environmental safety and the food chain.  We discuss in detail the preventive measures for the safe and sustainable use of nanomaterials in agriculture based on the application methods.  Furthermore, we summarize the role of antioxidant enzyme-triggering nanomaterials and direct reactive oxygen species (ROS) scavenging nanomaterials (nanozymes) in plant salt tolerance.  Nanomaterials can improve sodium (Na+) and potassium (K+) homeostasis through various anatomical, physiological, and molecular mechanisms while improving plant salt tolerance.  The role of nanomaterials in modulating plant photosynthesis and hormonal balance has been largely overlooked.  We also identify research gaps and provide guidelines for future research work.  This review provides guidelines for helping researchers to understand the proper design of nanoparticles (NPs) and different plant-related factors while using NPs for plant stress tolerance.  These considerations will help to improve the efficient delivery of NPs into plants.  Furthermore, after gaining sufficient scientific knowledge and better understanding, NPs can be integral to sustainable agriculture, while saving costs and reducing biosafety concerns and environmental pollution.
