摘要

干旱胁迫是一项重大的全球性挑战，它严重影响植物的生长、光合作用和养分吸收，导致大量减产。因此，有必要开发新的农业技术，而纳米技术就是其中之一。最近，纳米二氧化硅因其在缓解干旱和养分胁迫方面的重要作用而变得越来越重要。纳米二氧化硅的叶面/土壤施用和种子处理已证明可通过调节形态、生理和生化参数对干旱和养分胁迫下的植物产生积极影响。本综述旨在通过展示纳米二氧化硅对植物生长、气体交换属性、植物水分状态、膜稳定性、抗氧化活性和硅介导的养分吸收的有益影响，探讨纳米二氧化硅在提高植物抗干旱和养分胁迫能力方面的影响。此外，报告还概述了作物纳米硅营养方面的最新进展，并提出了未来的研究方向，以了解纳米硅在缓解干旱和养分胁迫方面的作用。

Fascinating role of nanosilica in mitigating drought and nutrient stress – A review

Drought stress is a major global challenge that severely impacts plant growth, photosynthesis and nutrient uptake, leading to significant yield losses. This necessitates the need for developing new agricultural technologies and one such advancement is nanotechnology. Recently, nanosilica has gained importance due to its significant role in mitigating drought and nutrient stress. The foliar/soil application and seed priming with nanosilica has shown to have positive impacts on plants under drought and nutrient stress by modulating morphological, physiological and biochemical parameters. This review aims to explore the impact of nanosilica in enhancing drought and nutrient stress tolerance in plants by demonstrating its beneficial effects on growth, gas exchange attributes, plant water status, membrane stability, antioxidant activity and silicon mediated uptake of nutrients. Further it also provides an overview of recent developments in nanosilica nutrition of crops and suggests future research directions to understand the role of nanosilica in alleviating drought and nutrient stress.

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
