The production by genetic engineering and the use of plasmids and bacterial strains are described, which contain the tfdA gene or a gene practically identical to the latter on a short DNA sequence which can be characterized with precision. These new plasmids and microorganisms are suitable for the production of 2,4-D mono-oxygenase (2,4-dichlorophenoxy acetic acid) and as starting materials for the transmission, by genetic engineering to various organisms, of the characteristic degradation of 2,4-D that this enzyme has. |
