Abstract: The invention relates to a method to inactivate plant genes. In one embodiment, the method comprises the steps of providing a viral vector comprising a cDNA sequence reverse transcribed from RNA of Cymbidium mosaic virus; constructing a recombinant plasmid containing a homologous gene fragment of the plant and the viral vector; preparing transcripts of the plasmid through in vitro transcription; infecting the plant with the transcripts; and forming siRNA from the transcripts to inactivate the homologous gene.

Abstract: Disclosed is a viral vector, whose transcripts induce gene inactivation in plants, comprising a cDNA sequence reverse transcribed from RNA of Cymbidium mosaic virus. In addition, the invention provides a method to inactivate plant genes, which comprises the steps of: (a) providing a viral vector comprising a cDNA sequence reverse transcribed from RNA of Cymbidium mosaic virus; (b) constructing a recombinant plasmid containing a homologous gene fragment of the plant and the viral vector; (c) preparing transcripts of the plasmid through in vitro transcription; (d) infecting the plant with said transcripts; and (e) forming siRNA from said transcripts to inactivate the homologous gene. The viral vectors and the method provided in the present invention can ensure the studies of the function of plant genes in a short period, and can be applied in screening plants with properties of commercial values and changing the plant characteristics.
