The invention relates to genetically modified TGB-3 viral sequences suitable to induce gene silencing. In particular, hairpin constructs based on such sequences proved highly efficient to induce a PTGS mechanism and degradation of the whole of RNA2 thereby. When plants are transformed accordingly, the spread of the virus in the plant is significantly reduced or blocked. The invention relates of the hairpin constructs, their use and to plants, plant cells and plant tissues harboring these constructs. |
