  • Constructs and methods to improve abiotic stress tolerance in plants
    Patent number: 11168334
    Abstract: Isolated polynucleotides and polypeptides, and recombinant DNA constructs, suppression DNA constructs and CRISPR/Cas9 DNA constructs are provided. Compositions (such as plants or seeds) with modified expression or activity of the isolated polypeptides are obtained by transforming the regenerable plant cell with a suppression DNA construct or CRISPR/Cas construct. The plants with improving drought tolerance are obtained by decreasing the expression or activity of the isolated polynucleotide.
    Type: Grant
    Filed: October 18, 2017
    Date of Patent: November 9, 2021
    Inventors: Guangwu Chen, Chengfeng Du, Yang Gao, Zantang Li, Guihua Lu, Guanfan Mao, Changgui Wang, Guokui Wang
  • Abiotic stress tolerant plants and methods
    Patent number: 10913954
    Abstract: Isolated polynucleotides and polypeptides, and recombinant DNA constructs are useful for conferring improved drought tolerance, and/or for regulating flowering time. Compositions (such as plants or seeds) comprise these recombinant DNA constructs; and methods utilize these recombinant DNA constructs. The recombinant DNA constructs comprise a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotides encode drought tolerance polypeptides and/or flowering time-regulating polypeptide.
