Heavy metals and toxic elements in plant cells: application of plants for remediation of polluted soil and their evaluations for food safety
Abstract
Present bilateral project is focused on detailed investigation of effects of various heavy metals and toxic elements on plant cells. Main targets of this project are to find out the cellular localization of particular heavy metals (Cd, Zn, Pb, Ni, Cu) and toxic metalloids (As, Sb), to describe the role of specific cell wall modifications in heavy metal and toxic element accumulation and plant tolerance, and to investigate physiological responses such as changes in the activity of pectin modifying enzymes, reactive oxygen species accumulation and MAPK signaling in three groups of plants: hyperaccumulators, widely used crops and model plant Arabidopsis. The establishment of bilateral cooperation, complementarity and combination of scientific methodologies used by Slovak and Austrian research teams would help to uncover the hidden aspects of heavy metals and toxic elements distribution and functioning in plant cells, and obtained results will provide a better insight into the actual topic of food safety and soil remediation.
