Originální abstrakt

Several transition metals are essential for plants as for most other organisms. These elements have been needed in the course of evolution because of their chemical properties such as redox activity under physiological conditions (Cu, Fe) or Lewis acid strength (Zn). The properties that make transition metal ions indispensable for life, however, are also the reason why they can easily be toxic when present in excess. The main threat lies in their ability to produce reactive oxygen species (ROS). Unfortunately, toxic metals such as cadmium, lead, mercury, etc., as well as the essential ones can also produce ROS. In the course of industrialization, emissions of metals have risen tremendously and significantly exceed those from natural sources for practically all metals. Due to this mobilization of metals into the biosphere, their circulation through soil, water, and air has greatly increased. The main aim of this chapter is to discuss the effects of metal ions on a plant cell, to summarize the current state of the art in the field of thiol-rich compounds like phytochelatins to detoxify metal ions.
