dc.description.abstractBeneficial effects of silicon (Si) are well demonstrated for many crop species, although its essentiality is SI still not proven. Some mechanisms of Si-mediated alleviation of different stresses in plants have been proposed in the literature, however the molecular bases of these mechanisms are poorly understood. Metal toxicity It, considered as an important environmental problem in many agricultural soils worldwide. Copper (Cu) is an essential microelement for plant growth and development. As a redox-active transition metal, Cu is a cofactor in many proteins involved in electron transfer chains including respiration and photosynthesis. However, in excess Cu can induce oxidative stress via several proposed mechanisms, including direct generation of ro active oxygen species (ROS) through the Fenton reaction. The aim of th is study was to elucidate the molecular mechanism of Si-mediated alleviation of oxidative stress caused by excess Cu in cucumber. Hydroponically grown plants were subjected to different Cu concentrations, with or without Si supply. The high Cu-treated plants showed higher biomass and better root growth when Si was applied. The parameters of oxidative stress lipid peroxidation, total phenolics and tissue Cu concentrations were measured. Expressions of the genes involved in antioxidative defense and biosynthesis of phenolics were in accordance with the biochemical findings, clearly demonstrating the multiple role of Si in alleviation the harmful effects of ROS in cucumber.sr
