Application of Gene Technology in Phytoremediation for Contaminated Soil by Heavy Metals

Soil pollution by heavy metals has become a global problem and urgently needs to be solved. Compared with traditional technology for recovery of polluted soil by heavy metals, phytoremediation technology exhibits such advantages as lower cost, protecting environment and easy acceptance to public, facilitating much attention from scientific field. The present paper describes in detail about phytoremediation of type, mechanism of the technology, advantage and disadvantage, application of gene technology in improving remediation ability and so on. It may be suggested that applying gene technology be an important aspect of phytoremediation.
