  • Patent number: 10612035
    Abstract: The present invention relates to the production of a non-transgenic plant resistant or tolerant to a herbicide of the phosphonomethylglycine family, e.g., glyphosate. The present invention also relates to the use of a recombinagenic oligonucleobase to make a desired mutation in the chromosomal or episomal sequences of a plant in the gene encoding for 5-enol pyruvylshikimate-3-phosphate synthase (EPSPS). The mutated protein, which substantially maintains the catalytic activity of the wild-type protein, allows for increased resistance or tolerance of the plant to a herbicide of the phosphonomethylglycine family, and allows for the substantially normal growth or development of the plant, its organs, tissues or cells as compared to the wild-type plant irrespective of the presence or absence of the herbicide. Additionally the present invention relates to mutant E. coli cells that contain mutated EPSPS genes.

  • Patent number: 10100334
    Abstract: Provided herein compositions and methods for producing isoprenoids, including squalene. In certain aspects and embodiments provided are genetically altered yeast and uses therefore. In some aspects and embodiments, the genetically altered yeast produce isoprenoids, preferably squalene. The genetically altered yeast may have alterations in the expression or activity of enzymes involved in squalene production, for example, acetyl-CoA carboxylase (or “ACCase”), HMG-CoA reductase, squalene epoxidase, and squalene synthase. One or more genes of a genetically altered yeast may be modified by gene repair oligonucleobases. Also are provided methods of producing squalene using a genetically altered yeast. The invention also provides squalene produced by genetically altered yeast.
