VERFAHREN ZUR GENETISCHEN VERÄNDERUNG EINER VIRALEN WILDTYP-SEQUENZ |
摘要 |
The present invention concerns a method of genetic modification of a TGB-3 wild type viral sequence for reducing or suppressing the possible deleterious effects of the agronomic properties of a transformed plant or plant cell by said TGB-3 viral sequence, comprising the following successive steps : submitting said sequence to point mutation(s) which allow the substitution of at least one amino-acid into a different amino-acid, selecting genetically modified TGB-3 wild type viral sequences having said point mutation(s) and which are not able to promote cell-to-cell movement of a mutant virus having a dysfunctional TGB-3 wild type viral sequence, when expressed in trans from a replicon, further selecting among said genetically modified TGB-3 viral sequences, the specifically genetically modified sequence which inhibits infection with a co-inoculated wild type virus when the mutant form was expressed from a replicon, and recovering said specifically genetically modified TGB-3 viral sequence. |
