A copper-inducible, Cre-loxP recombination-mediated DNA excision system has been developed in transgenic tobacco plants. The copper inducible system derived from yeast was used for the control of the expression of the Cre recombinase. Upon copper induction, the GVS reporter gene expression unit flanked by two direct lox sites was excised from the transgenic tobacco genome. Quantitative fluorometric GUS assays, Northern blot and PCR analyses showed a high-efficient, copper-dependent and Cre-loxP mediated DNA recombination in all the tested transgenic lines. The copper inducible foreign gene excision might be of great potential in genetic control of transgenic crops.
