Patents by Inventor Randal Arnold

Randal Arnold has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11111548
    Abstract: The invention provides methods for obtaining genetic material from plant embryos while preserving their viability as well as methods for performing a molecular analysis of plant embryos, particularly with small quantities of genetic material. The methods may include the steps of collecting shed cellular material from one or more embryos; obtaining DNA from the shed cellular material; performing a molecular analysis of the DNA; and germinating at least one of the one or more embryos. A further extension of this method includes determining whether to germinate and grow the embryo or to discard the embryo based on its genotype as part of a breeding process.
    Type: Grant
    Filed: August 29, 2014
    Date of Patent: September 7, 2021
    Inventors: Randal Arnold, Matthew Paul Cope, Justin Schares, Yue Yun
  • Patent number: 10477859
    Abstract: Methods for obtaining genetic material from plant embryos while preserving their viability are provided. In the methods, preservation of viability may be maintained by suspending the embryos in an aqueous solution surrounded by an oil matrix. Genetic material may be obtained from an aliquot of the aqueous solution and may be used directly for molecular analysis, or whole genome amplification may be performed prior to molecular analysis.
    Type: Grant

  • Patent number: 10278345
    Abstract: Methods for preserving viability of plant tissues such as plant embryos are provided herein. Also included are methods for storing genomic DNA and/or molecular marker assay materials in an oil bilayer as part of a high-throughput molecular characterization system. Moreover, plant embryos may be treated while in an oil matrix. The treatment may include chromosome doubling, Agrobacterium-mediated transformation, or herbicide selection as part of an embryo rescue process.
