  • Patent number: 9370149
    Abstract: Mutant rice resistant/tolerant to ACCase inhibiting herbicides, in particular FOP herbicides, are listed in Table 1. The ACCase inhibiting herbicides used for selection include quizalofop. An exemplary mutant rice tolerant to an ACCase herbicide is disclosed, with a rice genome having G2096S or the equivalent, in the carboxyl transferase domain of the ACCase coding gene, using the Black-Grass numbering system. This mutation shows differential response to FOPs vs. DIMs herbicides, and a greater differential with comparable non-resistant rice lines. Methods to control weeds and methods to produce herbicide resistant rice including transgenic rice, are disclosed.

  • Patent number: 9247706
    Abstract: Compositions and methods for reducing the level of nornicotine and N?-nitrosonornicotine (NNN) in tobacco plants and plant parts thereof are provided. The compositions comprise isolated polynucleotides and polypeptides for a root-specific nicotine demethylases, CYP82E10, and variants thereof, that are involved in the metabolic conversion of nicotine to nornicotine in these plants. Compositions of the invention also include tobacco plants, or plant parts thereof, comprising a mutation in a gene encoding a CYP82E10 nicotine demethylase, wherein the mutation results in reduced expression or function of the CYP82E10 nicotine demethylase. Seed of these tobacco plants, or progeny thereof, and tobacco products prepared from the tobacco plants of the invention, or from plant parts or progeny thereof, are also provided. Methods for reducing the level of nornicotine, or reducing the rate of conversion of nicotine to nornicotine, in a tobacco plant, or plant part thereof are also provided.

  • Patent number: 9234193
    Abstract: An isolated nucleic acid molecule encoding a 7-epizingiberene synthase, a chimeric gene comprising the nucleic acid molecule, vectors comprising the same, as well as isolated 7-epizingiberene synthase proteins themselves, are provided. In addition, transgenic plants and plant cells comprising a gene encoding a 7-epizingiberene synthase, optionally integrated in its genome, and methods for making such plants and cells, are provided. Especially Solanaceae plants and plant parts (seeds, fruit, leaves, etc.) with enhanced insect pest resistance are provided.

  • Patent number: 9175305
    Abstract: Compositions and methods for conferring hydroxyphenyl pyruvate dioxygenase (HPPD) herbicide resistance or tolerance to plants are provided. Compositions include amino acid sequences, and variants and fragments thereof, for mutant HPPD polypeptides. Nucleic acids that encode the mutant HPPD polypeptides are also provided. Methods for conferring herbicide resistance or tolerance, particularly resistance or tolerance to certain classes of herbicides that inhibit HPPD, in plants are further provided. Methods are also provided for selectively controlling weeds in a field at a crop locus and for the assay, characterization, identification and selection of the mutant HPPDs of the current invention that provide herbicide tolerance.
