  • Recombinase mediated gene traps
    Publication number: 20050144665
    Abstract: The present invention provides methods for identifying a genetically modified plant cell comprising a recombinase-mediated exchange between a first nucleotide sequence and a second nucleotide sequence. The present invention provides a method for obtaining a genetically modified plant cell wherein a functional recombination at both the 5? and 3? ends of the nucleotide can be identified.
