Patents by Inventor Raymond D. Shillito

Raymond D. Shillito 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).

  • Transformation of hereditary material of plants
    Publication number: 20010029619
    Abstract: A novel process for the direct transfer of foreign genes to plant genomes is described. The novel process comprises placing a gene under the control of plant expression signals and transferring it, by contact with protoplasts without the aid of natural systems for infecting plants, direct to plant cells from which genetically transformed plants can subsequently be derived.
    Type: Application
    Filed: February 20, 2001
    Publication date: October 11, 2001
    Inventors: Jerzy Paszkowski, Ingo Potrykus, Barbara Hohn, Raymond D. Shillito, Thomas Hohn, Michael W. Saul, Vaclav Mandak
  • Regeneration of graminaceous plants of the subfamily pooideae from protoplasts
    Patent number: 5596131
    Abstract: The present invention provides cell cultures derived from graminaceous plants which cultures are capable of being regenerated into plants, including fertile plants. Methods of accomplishing this regeneration are also provided. In addition, a novel procedure for the cryopreservation of embryogenic cell cultures is described.

  • Propagation process employing agarose medium
    Patent number: 4999299
    Abstract: The invention describes a process for culturing proliferating aggregates of plant cells, which comprises (a) uniformly plating isolated protoplasts, or isolated cells regenerated from protoplasts, in or on an agarose-solidified culture medium, and/or (b) cutting this pretreated and solidified culture medium into segments, transferring said segments to a liquid nutrient solution and continuing culturing in both cases until the cell aggregates have attained the desired size.
