The wide spread presence of polycyclic aromatic hydrocarbons(PAHs) and their potential harm to various organisms has generated interest in efficiently eliminating these compounds from the *** is an efficient technology for cleaning up ***,unlike microorganisms,plants lack the catabolic pathway for complete degradation of these dangerous groups of *** way to enhance the potential of plants for remediation of these compounds is by transferring genes involved in xenobiotic degradation from microbes to *** initiation of the microbial degradation of PAHs is catalyzed by naphthalene dioxygenase system,a multienzyme system including an electron transport chain(ETC) and a terminal ***,ETC is composed of two proteins:a flavoprotein reductase and a ferredoxin,and the terminal oxygenase composed of large and small *** this study,for the first time,we have successfully transferred the complex naphthalene dioxygenase system of Pseudomonas into Arabidopsis and rice,the model dicot and monocot *** in bacteria,all four genes of the naphthalene dioxygenase system can be simultaneously expressed and assembled to an active enzyme in transgenic *** naphthalene dioxygenase system can develop the capacity of plants to tolerate a high concentration of phenanthrene and metabolize phenanthrene in *** a result,transgenic plants showed improved uptake of phenanthrene from the environment over wild-type *** addition,phenanthrene concentrations in shoots and roots of transgenic plants were generally lower than that of wild type *** the naphthalene oxygenase of Pseudomonas was replaced by the terminal oxygenase of Mycobacterium vanbaalenii PYR-1,transgenic Arabidopsis plants overexpressing the heterozygous naphthalene dioxygenase system exhibited enhanced tolerance toward 2–4 rings *** plants assimilated PAHs from the culture media faster and accumulated less in vivo than wi
