  • Publication number: 20130267009
    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.

  • 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.

  • Patent number: 8338157
    Abstract: The invention relates to the field of molecular biology and recombinant nucleic acid technology. In particular, the invention relates to a rationally-designed, non-naturally-occurring meganuclease with altered DNA recognition sequence specificity which recognizes and cleaves a unique DNA site in the maize genome. Disclosed herein are meganucleases which are variants of the I-CreI and LIG-34meganucleases. The invention also relates to methods of producing engineered maize plants using such meganucleases.

  • Patent number: 8148605
    Abstract: A eukaryotic input circuit: computationally designed receptors, synthetic eukaryotic signal transduction pathways, and a synthetic signal sensitive promoter that allow highly specific transcriptional induction in response to an externally provided ligand is disclosed. The input circuit is able to specifically bind a targeted substance and transmit a signal to the nucleus where transcription of a gene is activated. An output circuit serves as a simple readout system of the substance detected by the input circuit. The readout circuit exemplified here is a degreening circuit which causes plants to turn white. Activation of the degreening circuit can be detected by eye, or remotely with a variety of machines (hand-held, aircraft or satellite based) and is also resettable. When linked the input circuit if operably linked to the output circuit, produces a functional plant detector.
