Annotation: The increased attention to the environmental contamination by heavy metals is paid over the last few decades. One of the potential environmental contaminants is antimony. Sb in large amounts enters the environment by anthropogenic activity. Nickel is considered as essential element that is toxic to most plants at higher concentrations. Ni is accumulated in soils mainly due to sewage sludge deposition, application of industrial compost or atmospheric fallout, near processing factories. In this project we will study the responses of maize plants stressed by Sb and Ni at the level of biomass production and at the biochemical (formation of ROS, activity of antioxidative enzymes) and physiological (membrane damage, changes in content and expression of proteins) level. We will determine whether the individual application of silicon or salicylic acid or their combination can protect maize plants from Sb or Ni toxicity by fine-tuning the antioxidative system of plants and/or improving plant growth and development.
