  • Non-diffusing plant virus vector
    Patent number: 9018444
    Abstract: The present invention is to provide a novel non-diffusing plant virus vector wherein virus vector infection and proliferation are possible only in a recombinant plant transformed with a gene necessary for viral proliferation, thereby enabling avoidance of unintended diffusion of a recombinant virus, a selective and specific expression system therefor, and a method of expression thereof which comprises combining a non-diffusing virus vector lacking a gene involved in intercellular movement of a cucumber mosaic virus (CMV) genome and a transgenic plant transformed with the lacked gene involved in intercellular movement for the non-diffusing virus vector to establish infection and proliferation selectively and specifically in the transgenic plant.

  • Non-Diffusing Plant Virus Vector
    Publication number: 20110138497
    Abstract: The present invention is to provide a novel non-diffusing plant virus vector wherein virus vector infection and proliferation are possible only in a recombinant plant transfected with a gene necessary for viral proliferation, thereby enabling avoidance of unintended diffusion of a recombinant virus, a selective and specific expression system therefor, and a method of expression thereof which comprises combining a non-diffusing virus vector lacking a gene involved in intercellular movement of a cucumber mosaic virus (CMV) genome and a transgenic plant transfected with the lacked gene involved in intercellular movement for the non-diffusing virus vector to establish infection and proliferation selectively and specifically in the transgenic plant.
