GENE SWITCH

摘要

A gene promoter sequence which responds to application of an exogenous chemical inducer such as one of the plant herbicide safeners is utilised as a gene switch to enable external control of expression of a gene placed under control of the promoter. A specific example of the gene switch construct is the maize GSTII (glutathione-S-transferase isoform II) enzyme promoter sequence which is induced by external application of the safener N,N-diallyl-2,2-dichloroacetamide.
