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.

P0 gene silencing constructs and use

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.

Method to develop herbicide-resistant sugar beet plants

The present 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.

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.

T227-1 flanking sequence

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.

Double fructan beets

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.

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.
