Plant Responses to Nanoparticle Stress

Abstract

With the rapid advancement in nanotechnology, release of nanoscale materials into the environment is inevitable. Such contamination may negatively influence the functioning of the ecosystems. Many manufactured nanoparticles (NPs) contain heavy metals, which can cause soil and water contamination. Proteomic techniques have contributed substantially in understanding the molecular mechanisms of plant responses against various stresses by providing a link between gene expression and cell metabolism. As the coding regions of genome are responsible for plant adaptation to adverse conditions, protein signatures provide insights into the phytotoxicity of NPs at proteome level. This review summarizes the recent contributions of plant proteomic research to elaborate the complex molecular pathways of plant response to NPs stress.

Interaction of metal oxide nanoparticles with higher terrestrial plants: Physiological and biochemical aspects

“…Previous reports have stated that MONPs are phytotoxic to various plant species (Ma et al 2015a). Perusal of all these phytotoxicity studies reveal that plant stress responses to MONPs have been evaluated extensively at physiological and biochemical levels (Hossain et al, 2015). In addition, summarized the impact of engineered nanomaterials in fruit/grain production of terrestrial plants grown until full maturity.…”

TiO2 and ZnO Nanoparticles Toxicity in Barley (Hordeum vulgare L.)

“…It is well known that nanoparticles can be transported by or can travel in aquatic environment and accumulate in soil and pass through to the food chain via plants . The soil‐plant systems profile may change due to the interferences of nanoparticles in soil .…”

Sulfur Nanoparticles Improves Root and Shoot Growth of Tomato

“…These methods have many disadvantages due to the difficulty of scale up the process, separation and purification of nanoparticles from the micro emulsions and energy requirements. Several studies were conducted to investigate the role of metal nanoparticles on plants growth (Farghaly & Nafady, 2015;Salama, 2012;Hafeez et al, 2015;Du et al, 2011;Jayarambabu et al, 2014). In previous work (Salem et al, 2016) we have reported the effect of sulfur nanoparticles on the growth and development of Cucurbita pepo.…”
