Abstract: In order to probe the efficiency of the RNAi strategy in protection plants against GFLV,we cloned a conserved segment of coat protein gene of GFLV (310 bp) by RT-PCR,constructed a RNAi plant expression vector by introducing this fragment into the destination vector of pHELLSGATE12 by gateway technology,and transformed into Nicotiana benthamiana by Agrobaterium mediated method.RT-PCR identification showed that the target gene fragment was integrated into the tobacco genome and showed expression in RNA level.We also evaluated the virus-resistance of the plants by virus inoculation.The results showed that the rate of disease occurrence in the transgenic positive lines was obviously lower than the control,indicating that the expressed dsRNAs in the transgenic plants may interfere the infection of this virus.

Key words: Grapevine fanleaf virus, RNA interference, Vector construction, Transgenosis, Nicotiana benthamiana
