  • METHOD FOR PRODUCING HAPLOID AND DOUBLED HAPLOID SUNFLOWER PLANTS BY MICROSPORE CULTURE
    Publication number: 20250268165
    Abstract: The present invention relates to a method for the production of haploid, polyhaploid and/or doubled haploid embryos, calli, seeds and/or plants of the species Helianthus annuus from isolated microspore cultures, more specifically to a method comprising contacting the isolated microspores with a histone deacetylase inhibitor (HDACi) and a complex protein composition. The present invention also provides a kit for producing a haploid, polyhaploid and/or doubled haploid embryo, callus, seed and/or plant of the species Helianthus annuus from at least one isolated microspore as well as the use of a histone deacetylase inhibitor (HDACi) and a complex protein composition for producing a haploid, polyhaploid and/or doubled haploid embryo, callus, seed and/or plant of the species Helianthus annuus. Finally, the present invention also relates to a population of haploid, polyhaploid and/or doubled haploid Helianthus annuus plants directly derived from at least one sunflower apical or lateral capitula.

  • ALS INHIBITOR HERBICIDE TOLERANT BETA VULGARIS MUTANTS
    Publication number: 20210054360
    Abstract: The present invention relates to an ALS inhibitor herbicide tolerant Beta vulgaris plant and parts thereof comprising a mutation of an endogenous acetolactate synthase (ALS) gene, wherein the ALS gene encodes an ALS polypeptide containing an amino acid different from tryptophan at a position 569 of the ALS polypeptide.
