  • Engineering of bolting resistance in sugar beet by means of the transgenic expression of the beet homologue of flowering time control gene FT
    Patent number: 8637737
    Abstract: This invention relates to the field of bolting and flowering time control in sugar beet, specifically to methods as well as nucleic acid molecules, chimeric constructs, and vectors for engineering bolting resistance in sugar beet by means of altering the expression of the Beta vulgaris homologues BvFT1 and BvFT2 of the FT gene. In particular, the present invention provides sugar beet plants having a phenotype of bolting resistance.

  • Transgenic plants and methods for controlling bolting in sugar beet
    Patent number: 8293977
    Abstract: This invention relates to the field of sugar beet bolting and flowering control, specifically methods and transgenic sugar beet plants for suppressing the vernalization response. In particular, the present invention includes sugar beet plants and methods for modulating sugar beet vernalization by over expression of an FLC gene or by suppressing AGL20 gene expression.

  • TRANSGENIC SUGAR BEET EVENT GM RZ13
    Publication number: 20120144516
    Abstract: A novel transgenic sugar beet event designated GM RZ13 is disclosed. The invention relates to nucleic acids that are unique to event GM RZ13. The invention also relates to assays for detecting the presence of the GM RZ13 event based on DNA sequences of the recombinant constructs inserted into the sugar beet genome that resulted in the GM RZ13 event and of genomic sequences flanking the insertion site. The invention further relates to sugar beet plants comprising the genotype of GM RZ13 and to methods for producing a sugar beet plant by crossing a sugar beet plant comprising the GM RZ13 genotype with itself or another sugar beet variety. Seeds of sugar beet plants comprising the GM RZ13 genotype are also objects of the present invention.
