  • Variegation in plants
    Patent number: 9145562
    Abstract: A variegated plant comprising a nucleic acid operatively linked to a regulatory region, the nucleic acid disrupts the expression of Cpn21. The nucleic acid is typically an antisense Cpn21 and the regulatory region may be an inducible regulatory region, a tissue specific regulatory region, or a developmental regulatory region.
    Type: Grant

  • Conditional sterility in wheat
    Patent number: 6384304
    Abstract: The invention relates to the use of a deacetylase coding sequence for obtaining conditional sterility in wheat. The invention relates to vectors comprising a deacetylase coding sequence under control of promoters which direct stamen-selective expression in wheat, which are particularly suited for the production of wheat plants which can be made male-sterile upon application of an acetylated toxin.
