Conclusion 1. In this study we successfully transferred the cytochrome P450 2E1 gene into Petunia by using Agrobacterium rhizogenes transgenic technology and obtained transgenic plants with high CYP2E1 expression. 2. The transgenic plants with high levels of CYP2E1 were efficient in removing benzene and toluene, and these plants had obviously improved ability of resistance to formaldehyde. 3. Our study is the first one to report that the CYP2E1 gene enhances the resistance ability of plants to formaldehyde. 4. Furthermore, four plants transplanted into the soil could flower normally, but were incapable of forming seeds. Whether this phenomenon is related to CYP2E1 transgenis will have to be addressed in subsequent studies. Conclusion Thanks！ Transgenic plants of Petunia hybrida harboring the CYP2E1 gene efficiently remove benzene and toluene pollutants and improve resistance to formaldehyde School of Life Science LongShan Li Background and Significance Materials and Methods The results Conclusion Contents Background and Significance 1. Benzene and toluene are common chemical components in paints, dyes, adhesives, wallpapers, carpets, synthetic fibers and detergents. 2. Using plants to clean chemical air pollution is economic，effective and non-destructive. 3. Although some natural plants have the capacity to decompose and purify, this is usually extremely inefficient. 4. Nevertheless, efficiency can be effectively improved by way of the transgenic technique. 5. Cytochrome P450 2E1 is a decomposition enzyme in mammalian liver, with the strong and specific capacity of decomposing organic pollutants in animal bodies. Background and Significance 6. The Doty group at the University of Washington successfully transferred the cytochrome P450 2E1 gene (CYP2E1) into the model plants tobacco and poplar. （2008） 7. These studies opened the door to a new method of reducing environmental threats by air pollution. Background and Significance Background and Significance The QL
