Progress of Phytoremediation: Focus on New Plant and Molecular Mechanism

Phytoremediation use plants to remove pollutants from the environment and render them harmless. It is an economically feasible and sustainable ways regarding to the remediation of our environment without introducing any new contaminants. Considering the vast diversity of pollutants and the different kinds of environmental conditions are two most important aspects that plants used for the remediation have to overcome, it is get more and more feasible for people looking for and developing new plants. Understanding the molecular mechanism of a plant’s responses to pollutant stress is the key to creating new plant species for this purpose through genetic engineering. In this review, we focus on the progress on searching for new plant species suitable for phytoremediation and the molecular mechanisms of their responses to pollutant stress. At the end, we propose some suggestions on how we can encourage the use of phytoremediation in the future.
