Abstract/Contents:"In order to find new plant resources for remediation of heavy metal contaminated soil, this experiment, which was carried out under hydroponic culture conditions, was to study lead uptake and tolerance of tall fescue with foreign DREB1A. The materials of this experiment were transgenic and non-transgenic plants. A month later, tested plants were treated with lead stress and the seven sets concentrations of lead were 100 mg/L, 200 mg/L, 500 mg/L, 1000 mg/L, 1500 mg/L, and 2000 mg/L. Three weeks later six indexes were measured which were the content and distribution of lead, the withering rate, the index of root tolerance, the translocation rate, bioaccumulation factor and translocation factor. The results showed that the growth satus [status] of the transgenic tall fescue were better than non-transgenic plants at the same condition and it was the same with the enrichment ability and the transport capacity. Whereas whether it was in the growth status or in the content and distribution of lead, two kinds of tall fescue on lead stress has basically the same trend. This showed that DREB1A gene had not changed the tall fescue on the transport mechanism for the transfer of lead, but improved the enrichment ability and the tolerance of tall fescue. All these proved that transgenic tall fescue is fit for phytoremediation of lead."
