  • Publication number: 20210123067
    Abstract: The invention provides novel methods and compositions for transfer of nuclear and/or plastomic genomes, or portions thereof, or cytoplasmic component(s) and/or genetic material, between plant cells. Methods for production of a wounded mixed cell culture, or mixing two or more cell cultures after wounding, and transfer of genetic and/or cytoplasmic component(s), such as transfer of nuclear and/or plastid gene(s) or mutations, edits or alleles, between cells of the mixed culture, are also provided. Wounded mixed cell cultures produced by such methods, and resulting cells and regenerated plants, plant parts, and progeny plants are further provided. Molecular and genetic analyses, and screenable and selection markers, are also provided to confirm transfer and presence of cytoplasmic and/or nuclear component(s) and/or gene(s), mutation(s) or allele(s) in cells and plants produced by these methods.

  • Patent number: 7572635
    Abstract: The present invention relates to a novel system for generating transformed dihaploid plants from haploid cells and tissues without the use of chromosome doubling agents.
    Type: Grant
    Filed: June 9, 2005
    Date of Patent: August 11, 2009
    Assignee: Monsanto Technology LLC
    Inventors: Charles L. Armstrong, David R. Duncan, Vladimir Sidorov
  • Publication number: 20040210959
    Abstract: The present invention relates to a novel system for generating transformed dihaploid corn plants. In particular, the invention relates to the production of haploid corn callus, transformation of that tissue, dihaploidization, and regeneration of transgenic plants. Transgenic dihaploid corn plants can then be easily produced.

  • Publication number: 20030204875
    Abstract: The present invention relates to a novel transformation system for generating transformed plants with lower copy inserts and improved transformation efficiency. In particular, the invention relates to the use of Agrobacterium growth inhibiting agents during the Agrobacterium-mediated transformation process that suppress Agrobacterium growth and reduce T-DNA transfer to the target plant genome.
