  • K85 mutation-containing plant EPSPS mutant, and encoding gene and application thereof
    Patent number: 11591580
    Abstract: The invention provides a plant EPSPS mutant (i.e. 5-enolpyruvylshikimate-3-phosphate synthase mutant), which is derived from plant, and has glyphosate resistance after mutation. Also provided is an encoding gene, which can encode the above plant EPSPS mutant; and a vector containing the above encoding gene; and a cell containing the above vector. Further provided are uses of the above plant EPSPS mutant.
    Type: Grant
    Filed: December 14, 2018
    Date of Patent: February 28, 2023

  • Plant EPSPS mutant containing L195P and S247G mutations and encoding gene and use thereof
    Patent number: 11584938
    Abstract: Provided are a plant EPSPS mutant containing mutations L195P and S247G and an encoding gene and the use thereof, related to the field of genetic engineering technology. Comparing the plant EPSPS mutant with E. coli EPSPS, the amino acid sequence of the plant EPSPS mutant has the mutation L195P at position 195 corresponding to E. coli EPSPS and/or the mutation S247G at position 247 corresponding to E. coli EPSPS. The mutation of either of the two sites or the simultaneous mutation of the two sites can confer or improve the resistance of the plant EPSPS mutant to glyphosate. Plants or recombinant bacteria for transforming the plant EPSPS mutant can grow normally in the presence of glyphosate.
