Plant growth and productivity are greatly impacted by temperature stress, both high and low. These stresses impair biochemical, physiological, and molecular processes in the plant, eventually affecting plant growth, development, and productivity. Consequently, novel approaches are needed to overcome these problems and achieve sustainability.
Nanotechnology is one such novel approach to improving crop production, by using nanoscale products. Nanoparticle size, nature, application mode, environmental conditions, rhizospheric and phyllospheric environments, and the species of plant make a significant impact on their action. With their easily soluble nature, smaller size, excellent ability to penetrate plants, and ability to cross cellular barriers, nanoparticles have become an increasingly popular agricultural tool. It has recently been observed that silver, silicon, titanium, and selenium nanoparticles can alter the physiological and biochemical response of plants in order to counteract high or low-temperature stress.
In this review, a description is provided of how nanoparticles are absorbed in different plant parts and how they are translocated along with the factors that influence their uptake and translocation. Also how plants respond to nanoparticles in temperature stress and the various types of physiological, morphological, anatomical, biochemical, and molecular modifications caused by nanoparticles. The review is going to provide researchers in agricultural sciences a glimpse into how to discover new nanoparticles to deal with heat stress.
