Nanotechnological Interventions in Agriculture

Abstract

Agriculture is an important sector that plays an important role in providing food to both humans and animals. In addition, this sector plays an important role in the world economy. Changes in climatic conditions and biotic and abiotic stresses cause significant damage to agricultural production around the world. Therefore, the development of sustainable agricultural techniques is becoming increasingly important keeping in view the growing population and its demands. Nanotechnology provides important tools to different industrial sectors, and nowadays, the use of nanotechnology is focused on achieving a sustainable agricultural system. Great attention has been given to the development and optimization of nanomaterials and their application in the agriculture sector to improve plant growth and development, plant health and protection and overall performance in terms of morphological and physiological activities. The present communication provides up-to-date information on nanotechnological interventions in the agriculture sector. The present review deals with nanoparticles, their types and the role of nanotechnology in plant growth, development, pathogen detection and crop protection, its role in the delivery of genetic material, plant growth regulators and agrochemicals and its role in genetic engineering. Moreover, the role of nanotechnology in stress management is also discussed. Our aim in this review is to aid researchers to learn quickly how to use plant nanotechnology for improving agricultural production.

Mycosynthesis of Silica Nanoparticles Using Aspergillus niger: Control of Alternaria solani Causing Early Blight Disease, Induction of Innate Immunity and Reducing of Oxidative Stress in Eggplant

“…The increase of phenolic compounds is an adaptive approach against disease [ 104 ]. Through our results, a significant increase in the content of proline and phenol was observed due to the addition of silica nanoparticles, especially concentration (100 ppm), which confirms the role of SiO 2 -NPs in inducing plant immunity, as the accumulation of proline in plants prevents damage to photosynthetic pigments by capturing free radicals that cause damage and failure in the photosynthesis process [ 105 , 106 ]. In these results, a clear and positive link to the use of SiO 2 -NPs in terms of improving vegetative growth characteristics, increasing the level of photosynthetic pigments, and raising the content of proline and phenol in infected plants cells, which supports the role of silicon in strengthening plant immunity against stress, which was confirmed by many previous studies [ 14 , 107 , 108 ].…”

Special Issue Physiological and Molecular Responses of Plants to Engineered Nanomaterials

“…The second review, written by Zishan Ahmad and coworkers [ 9 ], describes how nanoparticles and nanotechnology can play a significant role in plant growth, development, pathogen detection and crop protection, the delivery of genetic material, plant growth regulators and agrochemicals, and plant genetic engineering. They argue that agriculture has to face changes in climatic conditions, biotic and abiotic stresses that cause significant damages around the world, and the growing population demands.…”
