  • Plants Producing 2N Gametes or Apomeiotic Gametes
    Publication number: 20210163972
    Abstract: The invention relates to plants wherein the protein OSD1, involved in the transition from meiosis I to meiosis II is inactive. These plants produce Second Division Restitution (SDR) 2n gametes. The invention further relates to plants wherein the inactivation of OSD1 is combined with the inactivation of a gene involved in meiotic recombination in plants, and of a gene involved in the monopolar orientation of the kinetochores during meiosis. These plants produce apomeiotic gametes. These plants are useful in plant breeding.

  • Increase in meiotic recombination in plants by inhibiting an RECQ4 or TOP3A protein of the RTR complex
    Patent number: 10920237
    Abstract: The invention relates to a method for increasing the frequency of meiotic recombination in plants, by inhibiting the RECQ4 or TOP3A protein, especially by mutagenesis or extinction of the RECQ4 or TOP3A gene coding for said protein. The invention can be used especially in the field of plant breeding and genetic mapping.

  • Dominant mutation in the gene leading to diplogametes production in plants
    Patent number: 10674686
    Abstract: The invention relates to a dominant mutation in the TDM gene leading to the production of 2n gametes in plants, to the plants comprising said mutation, and to their use in plant breeding. The invention relates also to plants in which the dominant mutation in the TDM gene is combined with the inactivation of a gene involved in meiotic recombination in plants and a gene involved in the monopolar orientation of the kinetochores during meiosis. These plants which produce apomeiotic gametes are also useful in plant breeding.
