Abstract
Nanotechnology has the potential to revolutionize agriculture field. Towards this effort, carbon nanotubes have recently been reported to induce growth enhancement of tobacco cells. In this study, exposure to 24 nm size gold nanoparticles (GNPs) at 10 μg/ml concentration was found to enhance the total seed yield of Arabidopsis thaliana by 3 times over the control. In addition, 24 nm size GNP exposure at both 10 and 80 μg/ml concentrations has significantly improved seed germination rate, vegetative growth and free radical scavenging activity. A considerable correlation was found between expression of key plant regulatory molecules, microRNAs (miRs) and seed germination, growth and antioxidant potential of A. thaliana on GNP exposure. This is the first report showing GNPs as a promising tool to enhance seed yield of plants.
