  • Termination of transgene expression via transposon-mediated break
    Patent number: 8524979
    Abstract: This invention provides a genetic construct comprising: (a) a DNA cut-and-paste transposon genetic unit which comprises a transposase gene flanked on either side by inverted repeat sequences and operably under the control of a first promoter; and (b) a transgene unit which comprises an expressable transgene, placed operably under the control of a second promoter; wherein the transposon genetic unit and the transgene unit are linked with one of the inverted repeat sequence located in an intron of the transgene. This invention also provides methods of transiently expressing a transgene in a stably transformed eukaryote. This invention further provides methods for obtaining marker-free transgenic plants.
    Type: Grant

  • Inducible one-component plant gene tagging
    Patent number: 6369297
    Abstract: A nucleic acid including (1) an inducible transposable element having a first nucleotide sequence encoding a transposase, and an inducible promoter operably linked to the first nucleotide sequence; (2) an uncoupled promoter; and (3) a second nucleotide sequence encoding a polypeptide such that, upon removal of the inducible transposable element during transposition, the uncoupled promoter becomes operably linked to the second nucleotide sequence.
