| 摘要 |
The present invention relates to modified tetracycline-inducible cassettes for controlling gene expression in organisms, particularly plants. Specifically, the invention provides novel tetracycline repressor and operator cassettes. The invention preferably provides a tetracycline-inducible expression cassette comprising both the tetracycline repressor and operator cassettes of the present invention wherein the repressor and operator cassettes are located on a single plasmid and/or vector. Also provided is a method of producing herbicide resistant plants using the modified tetracycline inducible cassettes of the present invention to control the expression of a herbicide resistance gene. Moreover, a method for identifying novel tetracycline analogs and/or functional equivalents using the modified tetracycline inducible cassettes of the present invention is also presented. |
