  • ?-solanine/?-chaconine rhamnosyl transferase sequences and uses thereof
    Patent number: 7439419
    Abstract: Nucleic acid sequences from potato that encode the enzyme ?-solanine/?-chaconine rhamnosyltransferase (SGT3) are disclosed. Recombinant DNA molecules containing the sequences, and use thereof, in particular, use of the sequences and antisense constructs to inhibit the production of SGT3 and thereby reduce levels of the predominant steroidal glycoalkaloids ?-chaconine and ?-solanine in Solanaceous plants such as potato are described.
    Type: Grant
    Filed: November 14, 2005
    Date of Patent: October 21, 2008
    Assignee: The United States of America as represented by the Secretary of Agriculture
    Inventors: Kent F. McCue, Paul V. Allen, David R. Rockhold, Louise V. T. Shepherd, Mary M. Maccree, Howard V. Davies, William R. Belknap
  • sterol alkaloid glycosyltransferase (SGT) a novel solanidine glucosyltransferase SGT2 and uses thereof
    Patent number: 7375259
    Abstract: Nucleic acid sequences from potato that encode the enzyme UDP-glucose:solanidine glucosyltransferase (SGT2) are disclosed. Recombinant DNA molecules containing the sequences, and use thereof, in particular, use of the sequences and antisense constructs to inhibit the production of SGT2 and thereby reduce the level of the more human-toxic of the two predominant steroidal glycoalkaloids ?-chaconine and/or increase the level of the more insect-toxic ?-solanine in Solanaceous plants such as potato are described.
