Plant Response to Gold Nanoparticles
Springer Nature
In this book, overall plant and soil system are examined exclusively in terms of gold nanoparticles (Au-NPs) exposure. Au-NPs influence plant growth and yield performance. They also affect plant and soil system interactions. Au-NPs responses are primarily depends on the concentration, plant species or cultivars, exposure time, shape and size of NPs. Investigation have shown that the lower concentrations of Au-NPs increase seed germination, beneficial biochemical components, rate of photosynthesis, and overall growth, however, at higher concentrations, all these responses are declined in different plant species. At higher concentration, Au-NPs induce stress in plant, create phytotoxicity and produce reactive oxygen species which leads to the disruption of cellular metabolism. Further, at higher concentration, Au-NPs hampered the physico-chemical process of plant and soil system. Moreover, the molecular and physiological performance showed that the exposure of Au-NPs resulted in oxidative stress and induced antioxidative and defense responses. The energy production related to metabolic pathways were also influenced by Au-NPs exposure. Au-NPs exposure accelerated the number of…
