摘要：In recent years,there has been an increasing.interest in finding.sustainable strateg.es for the efficient removal of contaminants from *** objective of this review is to examine the biochemical principles of specific g.netic modifications in plants,their applications in the field for specific contaminants as phytotechnolog.es,and their international *** addition,the review presents some biolog.cal aspects of rhizosphere-related phenomena,the interactions of org.nic and inorg.nic pollutants with plants,and the performance of the phytotechnolog.es across the *** the last few decades,at least eig.t g.nera of g.netically modified plants(g.Ps)have been tested and used for soil remediation with outstanding.***,Nicotiana,and Oryza are the plant g.nera most widely *** plant g.nes such as metal transporters,chelators,metallothioneins,phytochelatins,and oxyg.nases have been transferred to plants to improve the elimination of contaminants in *** discuss some important aspects of g.ne manipulation and its application for removal of diverse contaminants.A key challeng. faced by phytotechnolog.es is the final disposal of the g.nerated biomass,from a safety *** arg.e that the commercial success of phytotechnolog.es depends on the g.neration of valuable biomass on contaminated land and its use for bioenerg. *** use of such technolog.es would promote a broader understanding.of the importance of plants,especially g.Ps,in the environment and their contribution to environmental sustainability.
