Brief Overview:

Several plant species have been identified and employed for years in bioremediation efforts (Peuke and Rennenberg, 2005). Among these the species Silene vulgaris (Moench.) has been utilized for similar purposes (especially for the up-take of copper and zinc from soils) in European countries. The purpose of this work consisted in reviewing current literature to learn the absorption modality of these ions by the plant under study, identify the genes involved in the process and locate the evolution of this trait in the phylogenetic tree of the species.
