Barbora Szotáková, Ph.D. Consultant: RNDr. Radka Podlipná, Ph.D. Title of diploma thesis: Modulation of expression and activity of selected plant detoxifying enzymes by anthelmintic Anthelmintics represent risk to environment as they may impact non-target organisms including plants, which come into contact with these pharmaceuticals in fields by fertilization with dung from treated animals or in pastures by excrements of treated animals. After uptake, these substances can increase the production of reactive oxygen species in plants, with the risk of oxidative stress and plant damage, and also affect the antioxidant enzymes. The aim of this work was to investigate the effect of two widely used anthelmintics ivermectin and fenbendazole on the activity and expression of selected antioxidant enzymes in soybean (Glycine max). Soybean was cultivated in a greenhouse and watered with a 10 µM solution of the selected drug. The changes of activity and gene expression of antioxidant enzymes were measured in root, leaf, pod and seed samples. Results showed that both anthelmintics caused significant decrease of superoxide dismutase, ascorbate peroxidase, glutathione...
