  • Nucleic acid sequences encoding flavonoid 3?-hydroxylase and methods of altering flower color therewith
    Patent number: 6774285
    Abstract: The present invention relates generally to nucleic acid sequences encoding flavonoid 3′-hydroxylase (hereinafter referred to as “F3′H”) and their use in the manipulation of pigmentation in flowers of plants.
    Type: Grant
    Filed: March 29, 1999
    Date of Patent: August 10, 2004
    Assignee: Florigene Limited
    Inventors: Filippa Brugliera, Timothy Albert Holton, Michael Zenon Michael
  • Stem-loop vector system
    Publication number: 20040115616
    Abstract: The present invention relates generally to a method for generating a nucleic acid library. More particularly, the present invention provides a library of eukaryotic-derived nucleic acid molecules inserted into vectors and maintained in a prokaryotic microorganism or as isolated and/or purified nucleic acid molecules. Such molecules are useful for transforming or otherwise being introduced to eukaryotic cells which can then be screened for transcriptional or post-transcriptional gene silencing (TGS or PTGS) events.

  • Transgenic plants exhibiting altered flower color and methods for producing same
    Patent number: 6080920
    Abstract: The present invention relates generally to novel approaches in generating transgenic plants exhibiting altered flower colour by the introduction of a nucleotide sequence encoding dihydroflavonol-4-reductase (DFR) which preferably acts on dihydromyricetin (DHM). More particularly, the present invention provides transgenic carnation plants and flowers cut therefrom exhibiting flower colouration not naturally associated with carnation plants. The present invention further contemplates methods for producing transgenic carnation plants with the altered flower colour.
    Type: Grant

    Date of Patent: June 27, 2000
    Assignee: International Flower Developments Pty. Ltd.
    Inventor: Timothy Albert Holton
  • Transgenic plants having altered anthocyann levels
    Patent number: 5948955
    Abstract: The present invention relates generally to transgenic flowering plants. More particularly, the present invention is directed to transgenic rose, carnation and chrysanthemum plants genetically modified to enable expression of flavonoid 3',5'-hydroxylase thereby permitting the manipulation of intermediates in the flavonoid pathway.
    Type: Grant

  • Genetic sequences encoding flavonoid pathway enzymes and uses therefor
    Patent number: 5861487
    Abstract: The present invention relates to a nucleic acid isolate comprising a sequence of nucleotides encoding, or complementary to a sequence encoding, a dihydrokaempferol (DHK) hydroxylating enzyme or derivative or part thereof. The present invention also relates to transgenic plants carrying and expressing the above mentioned nucleic acid material.
    Type: Grant

  • Genetic sequences encoding flavonol synthase enzymes and uses therefor
    Patent number: 5859329
    Abstract: The present invention relates generally to genetic sequences encoding flavonoid pathway metabolising enzymes and in particular enzymes having flavonol synthase activity and their use such as in manipulating production of pigmentory molecules in plants. More particularly, the present invention provides genetic sequences encoding flavonol synthase (FLS).
    Type: Grant
