Disclosed is a plant transformation construct comprising DNA having
(1) a ring-opening gene that encodes an enzyme that can open an aromatic ring,
(2) upstream of the ring-opening gene, a eukaryotic promoter, and
(3) downstream of said ring-opening gene, a polyadenylic acid addition site.
Also disclosed is a plasmid that contains the plant transformation construct and bacteria that contain the plasmid. A transgenic plant cell that contains, as part of its genome, the plant transformation construct is also disclosed, and a transgenic plant is grown from the transgenic plant cell. Also disclosed is a method of degrading aromatic compounds in soil by planting the transgenic plant in the soil.
本发明公开了一种植物转化构建体,其 DNA 具有以下特征
(1) 开环基因,该基因编码一种能打开芳香环的酶、
(2) 开环基因上游的真核启动子,以及
(3) 开环基因下游的多聚腺苷酸添加位点。
还公开了含有植物转化构建体的质粒和含有该质粒的细菌。还公开了一种转基因植物细胞,作为其基因组的一部分,该细胞含有植物转化构建体,并由该转基因植物细胞培养出转基因植物。还公开了一种通过在土壤中种植转基因植物来降解土壤中芳香化合物的方法。
