Title:
TRANSGENIC CROP BEING SELECTIVELY KILLED, PREPARATION AND UTILIZATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/083598
Kind Code:
A1
Abstract:
A method for preparing transgenic gramineal plants that could be selectively killed by herbicides. The method comprises inhibiting the expression of detoxifying P450 genes and the degradation of the herbicides by using antisense RNA of P450 genes in the transgenic plants, thereby the resulting plants could be selectively killed by bentazon and sulfonylurea-type herbicides, and the spreading and mix of these plants into non-transgenic plants could be prevented.
