عنوان Mechanisms of Nanoparticle-Mediated Stress Alleviation in Plants

نویسندگان ّFatemeh Amini

چکیده Abiotic stresses, such as drought, salinity, temperature extremes, and heavy metal toxicity, are significant limiting factors for plant growth and agricultural productivity worldwide. With climate change exacerbating the frequency and intensity of these stresses, innovative solutions are urgently needed to enhance plant resilience. Nanotechnology, particularly the use of metal oxide nanoparticles (NPs), has emerged as a promising strategy for improving plant tolerance to abiotic stresses. This review discusses the potential of nanoparticles, specifically titanium dioxide (TiO₂) and zinc oxide (ZnO) nanoparticles, in mitigating the effects of environmental stressors. These nanoparticles exert their effects through various mechanisms, including enhancing water and nutrient uptake, modulating plant hormone levels, boosting antioxidant defenses, and improving root growth. The review also highlights the application of TiO₂ and ZnO nanoparticles in alleviating specific stresses, such as salinity, drought, and heat, while addressing the challenges associated with their use in agriculture. Despite promising results, further research is needed to optimize nanoparticle formulations and ensure their safe and effective application in sustainable agricultural practices.
