    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.

  • Publication number: 20170306349
    Abstract: The present disclosure includes the production of a mutant plant resistant to an herbicide of the phosphonomethylglycine family, e.g. glyphosate. Compositions and methods are provided for editing a nucleotide sequence of interest in a cell employing a guide polynucleotide/Cas endonuclease system, wherein the Cas endonuclease is guided by a guide polynucleotide to recognize and optionally introduce a double strand break at a specific target site into the genome of a cell. The nucleotide sequence of interest to be edited can be located within or outside the target site that is recognized by a Cas endonuclease. More specifically, compositions and methods are provided for editing an enolpyruvylshikimate-3-phosphate synthase (EPSPS) nucleotide sequence in a cell. The methods and compositions employ a guide polynucleotide/Cas endonuclease system to provide for an effective system for editing EPSPS nucleotide sequences of within the genome of a cell.
