Abstract: The present invention include a recombinant BMYV P0 viral nucleotide sequence, which when transcribed in a cell, is capable of forming a double stranded self-complementary RNA sequence. The invention is related to a method for conveying viral resistance or tolerance to one or more virus(es), in particular to beet mild yellowing virus (BMYV) and to beet necrotic yellow vein virus (BNYVV) or to BMYV alone in a plant, in particular in a sugar beet plant. Furthermore, the present invention relates to the virus-resistant or -tolerant plant obtained according to this method, as well as to seeds and progeny derived therefrom.

Abstract: 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.

Abstract: 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.

Abstract: A method for 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 Transcription Activator-Like Effector Nucleases (TALEN) or one or more vectors including sequences encoding these Transcription Activator-Like Effector Nucleases (TALEN)sequences. The TALEN target and process a target sequence and replace the target sequence through homologous recombination with the nucleic acid construct including the nucleotide sequence of interest, -possibly applying to an in vitroculture of the protoplasts, a medium that is toxic, preferably lethal to the in vitroculture of the protoplasts.

Abstract: A herbicide resistant transformed sugar beet that is detectable by the specific primers developed to match the DNA sequences that flank the left and/or right border region of the inserted transgenic DNA and the method of identifying primer pairs containing plant genomic DNA/plasmid DNA. More specifically, the present invention covers a specific glyphosate resistant sugar beet plant having an insertion of the transgenic material identified as the T227-1 event. The present invention additionally covers primer pairs: plant genomic DNA/Plasmid DNA that are herein identified. Additionally, these primer pairs for either the left or the right flanking regions make an event specific test for the T227-1 insert of transgenic material.

Abstract: The present invention relates to fructan producing plants particularly to methods for the production of fructans having a low degree of polymerization. The invention is also directed to non-fructan producing plants which are transformed or crossed to contain at least two of three genes encoding a fructosyltransferase.

Abstract: The present invention concerns a method for inducing resistance to a virus comprising a TGB3 sequence with the proviso that it is not the potato virus X, into a plant cell or plant, comprising the following steps: preparing a nucleic acid construct comprising a nucleic acid sequence corresponding to at least 70% of the nucleic acid sequence of TGB3 of said virus or its corresponding cDNA, being operably linked to one or more regulatory sequence(s) active in a plant, transforming a plant cell with the nucleic acid construct, and possibly regenerating a transgenic plant from the transformed plant cell. The present invention is also related to the plant obtained.

Abstract: Plants may be regenerated from stomatal cells or protoplasts of such cells. Prior to regeneration the cells or protoplasts may be genetically transformed by the introduction of hereditary material most preferably by a DNA construct which is free of genes which specify resistance to antibiotics. The regeneration step may include callus formation on a hormone-free medium. The method is particularly suitable for sugar beet.
