  • METHODS FOR PRODUCING A COMPLEX TRANSGENIC TRAIT LOCUS
    Publication number: 20130263324
    Abstract: Methods for producing in a plant a complex transgenic trait locus comprising at least two altered target sequences in a genomic region of interest are disclosed. The methods involve the use of two or more double-strand-break-inducing agents, each of which can cause a double-strand break in a target sequence in the genomic region of interest which results in an alteration in the target sequence. Also disclosed are complex transgenic trait loci in plants. A complex transgenic trait locus comprises at least two altered target sequences that are genetically linked to a polynucleotide of interest. Plants, plant cells, plant parts, and seeds comprising one or more complex transgenic trait loci are also disclosed.

  • Rationally-designed single-chain meganucleases with non-palindromic recognition sequences
    Patent number: 8445251
    Abstract: Disclosed are rationally-designed, non-naturally-occurring meganucleases in which a pair of enzyme subunits having specificity for different recognition sequence half-sites are joined into a single polypeptide to form a functional heterodimer with a non-palindromic recognition sequence. The invention also relates to methods of producing such meganucleases, and methods of producing recombinant nucleic acids and organisms using such meganucleases.
