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.
