  • Method for preparing barley green regenerative tissue
    Patent number: 6541257
    Abstract: A method of preparing green regenerative tissue of barley suitable for transformation is presented. The method includes incubating barley tissue on a callus induction medium under dim light. The dim light conditions are sufficient to produce green regenerative tissue. The callus induction media includes auxin and copper.
    Type: Grant
    Filed: April 3, 2001
    Date of Patent: April 1, 2003
    Assignee: The Regents of the University of California
    Inventors: Peggy G. Lemaux, Myeong-Je Cho
  • Methods and compositions for transformation of cereals using cultured shoot meristematic tissue
    Patent number: 6486384
    Abstract: Methods for transforming plants, particularly commercial genotypes of cereals, are provided. The methods involve transformation of meristematic organogenic tissue, and include the use of defined plant growth media. The methods disclosed provide more stable transgenic plants, and permit the transformation of varieties of cereals that are not amenable to transformation by conventional approaches.
    Type: Grant
    Filed: September 23, 1998
    Date of Patent: November 26, 2002
    Assignees: The Regents of the University of California, The United States of America as represented by the Secretary of Agriculture
    Inventors: Shibo Zhang, Myeong-Je Cho, Phillip Bregitzer, Peggy G. Lemaux
  • Barley gene for Thioredoxin and NADP-thioredoxin reductase
    Patent number: 6380372
    Abstract: The present invention provides barley thioredoxin h nucleic acids and proteins. The barley thioredoxin h nucleic acid may be isolated or it may be an expression vector. The expression vector may be operably linked to a transcriptional regulatory sequence. The invention also provides for transgenic plants comprising recombinant barley thioredoxin h. The invention also provides methods of expressing and purifying barley thioredoxin h.

  • Compositions and methods for plant transformation and regeneration
    Publication number: 20010031496
    Abstract: Improved compositions and methods for transformation and regeneration of plants from embryogenic callus are disclosed that include, for example: use of an intermediate-incubation medium after callus induction to increase the competence of the transformed cells for regeneration; dim light conditions during early phases of selection; use of green callus tissue as a target for microprojectile bombardment; and media with optimized levels of phytohormones and copper concentrations.
