The present invention provides an RNAi plant expression vector for herbicide-dominant inhibition of HSL1 and application thereof, as well as a method for interfering with the expression of plant HSL1 (HIS1-Like) and a method for obtaining herbicide-dominant sensitive plants. Transforming the RNAi plant expression vector of the present invention into rice can successfully inhibit the expression of the gene HSL1, and change the rice from being resistant to herbicides to being sensitive, so that sensitive plants can be eliminated by applying herbicides, thereby cultivating a Herbicide-dominant sensitive rice. The rice has important application value in cultivating new transgenic varieties, producing hybrid rice seeds, and preventing transgenic escape. |
