Abstract
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.
