Heavy metals soil contamination is the global problem affecting plant growth and development and limiting successful plant´s distribution and crop production. Plants do not possess effective mechanisms to escape the polluted environment, therefore they should live and survive exposed directly to stress conditions.

How do the plants response to heavy metal exposure at the seedling stage?
Which are the symptoms of stress exposure and the mechanisms of heavy                metals phytotoxicity?
What is the role of antioxidant and hydrolytic enzymes in response to heavy                metals?
When are reactive oxygen species effective signalling molecules and when a                tool leading to cell death?
How are the enzymes producing reactive oxygen species involved in heavy                metals stress response?

The mission of our laboratory is to deal with similar questions and to contribute to general knowledge on stress-induced physiological processes.


We are particularly interested in examining:

  • the responses of aluminium and cadmium - exposed barley roots at the seedling stage
  • the changes in enzyme activities and isoenzyme pattern (enzymes involved in reactive oxygen species production, antioxidative and hydrolytic enzymes, ascorbate-related enzymes)
  • the activation and inhibition of proteins involved in heavy metal sequestration
  • the production of reactive oxygen species in root tissues and root border cells
  • the expression of genes involved in stress response
