Beschreibung
Zusammenfassung:	The invention provides a mercury transporter gene merT from pseudomonas transferred into Arabidopsis. The transgenic plant can achieve an effect of improving the mercury resistance of the plant. The sequence of the gene merT is shown as the sequence 1, the sequence of proteins coded by the gene merT is shown as the sequence 2, the Arabidopsis is transformed by the gene, the expression amount of antioxidant enzymes of the obtained transgenic plant is improved by 2 times to tens times on a flat plate containing high-concentration Hg, and the root length is increased by over 45 percent compared with that of a non-transgenic plant. According to the genes disclosed by the invention, the plant can be promoted to take participate in degradation of Hg, so that the capacity of degrading Hg in the transgenic plant is improved, and a useful help is provided for recovering Hg pollution by using plants.
