Abstract: Chemical-inducible promoters can activate or inactivate target gene expression at a particular developmental stage and for a specific duration. Several systems have been developed and used to analyze gene function， marker-free plant transformation， site specific DNA excision， restoration of male fertility and RNA silencing. Chemical-inducible expression systems will be powerful tools for basic research in molecular biology and biotechnological applications， which will dramatically increase the application of transgenic technology.
