Nanotechnology a tool for Sustainable Agriculture against stress: An assessment

Abiotic and biotic factors are the major causes that affect the productivity of crops. Many tools of modern science have been widely applied for crop improvement under environmental stress. In this way, nanotechnology is the major green technologies which are provided to the protection of plants against stress. Under various stress condition nanoparticles are the major contributor to increasing germination, seedling growth, physiological activities including photosynthesis and nitrogen metabolism, leaf activities of CAT, POX, and APX, chlorophyll contents, protein, carbohydrate contents, and yield, and also positive changes in gene expression indicating their potential use in crop improvement. Therefore, selection of nanotechnology for crops improvement will be very useful tool. Nanoparticles enhances root hydraulic conductance and water uptake in plants and showing differential abundance of proteins involved in oxidation-reduction, ROS detoxification, stress signaling, and hormonal pathways. The mobility of the nanoparticles is very high, which leads to rapid transport of the nutrient to all parts of the plant. In particular, the most actual is to find ways to increase the adaptation potential of cultivated plants with the use of Nano particles in stressful conditions
