Genetically modified plants and strategies for treatment of soil with heavy metals

Heavy metals both these trace elements necessary for life , as well as those niepełniące any physiological functions constitute a serious threat to human and animal health . Human activities has led to the emergence of huge amounts of these metals in soils around the world. Due to the high toxicity of heavy metals , there is an urgent need to develop more efficient and cheaper methods of soil remediation . Conventional methods of soil remediation are inefficient and expensive , and often result in the destruction of natural habitats .

Characteristics of plant antyporterów cation / proton type CAX

Plants for proper growth and development require a certain concentration of macronutrients and micronutrients. However, high concentrations of metals , both necessary and ballast are very toxic to living organisms. Plants, as nieprzemieszczające organisms during the life cycle, generated collection mechanisms governing processing , distribution and storage of ions or other substances . In recent years in plant cells have been identified and characterized initially various systems involved in the active transport of metal ions moving across the cell membrane .

The role of the thiol compounds in plants under stress induced by heavy metals

Almost all soils has seen a steady increase in the content of heavy metals, mainly due to anthropogenic activities . The presence of elevated concentrations of metals has a number of adverse changes in the functioning of the plant cell.
