Abstract: The present invention relates to inducible transcription control sequences for the regulation of gene expression. Specifically, it relates to an transcription control sequence comprising at least two tet operator sequence motifs allowing the binding of tetracycline-dependent transcriptional regulators, wherein each of the tetracycline-dependent transcriptional regulators binds with respect to its neighbor to an opposite face of the DNA helix, and a minimal promoter comprising a TATA box which is linked at its 5? end to a general transcription factor binding site. Further, the present invention relates to a vector, a host cell, a plant or a non-human transgenic animal comprising the transcription control sequence. Also contemplated is a method for regulating the expression of a nucleic acid sequence being operatively linked to the transcription control sequence of the present invention in a host cell, a plant or a non-human transgenic animal.
