摘要:
A method for the transformation of sugar beet protoplasts includes obtaining protoplasts from stomatal guard cells isolated from a sugar beet plant. The protoplasts are transformed with a nucleic acid construct including a nucleotide sequence of interest and a selection marker sequence. One or more ALS inhibitors at a concentration that is lethal to the in vitro culture of the protoplasts are applied to an in vitro culture of the protoplasts. Sugar beet plants are regenerated from the surviving protoplasts having integrated the nucleic acid construct including the sequence of interest and the selection marker sequence. The selection marker sequence is the mutated BvALS113 sequence carrying in its sequence a mutation at amino acid 113 position from Alanine to Tyrosine.

A method for producing herbicide-resistant sugar beet plant includes obtaining protoplasts from stomatal guard cells isolated from a sugar beet plant. A composition having an ALS herbicide is applied to the cells at a concentration which is lethal to the cells. Sugar beet plants are regenerated from the surviving cells.

The present invention is related to a recombinant BMYV P0 viral nucleotide sequence when transcribed in a cell is capable of forming a double stranded self-complementary RNA sequence.

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.
