  • Patent number: 11939588
    Abstract: Described herein are modified plants, plant cells, and plant seeds that have at least one mutant loss-of-function JAZ gene and at least one loss-of-function cdk8 gene. Such plants are highly resistant to pests and environmental stress and have restored growth and increased seed yield compared to plant lines with a jazD genetic background.
    Type: Grant
    Filed: October 15, 2020
    Date of Patent: March 26, 2024
    Assignee: Board of Trustees of Michigan State University
    Inventors: Gregg A. Howe, Qiang Guo
  • Publication number: 20230365987
    Abstract: Plants, plant cells, and seeds are described herein that grow well and are resistant to environmental stresses such as drought and insects, where the plants have one or more mutations that reduce or eliminate the interaction of MYC transcription factors with the JAZ proteins. The plants can have an additional mutation that reduces or eliminates the function of the PHYB gene, and/or a heterologous PIF4 transgene or PIF4 expression cassette to improve the growth of the myc mutant plants. Methods of making and using such plants, plant cells, and seeds are also described.

  • Patent number: 9796984
    Abstract: The present invention relates to genes, proteins and methods comprising molecules that alter amino acid levels. In one embodiment, the present invention relates to altering guanidino substrate hydrolysis activities in plants, arthropods and microorganisms using molecules within the arginase family and other molecules that alter an amino acid levels. In ones embodiment, the present invention relates to altering threonine substrate deamination and dehydration activities in plants, arthropods and microorganisms using molecules within the threonine deaminase family and other molecules that alter amino acid levels. In one embodiment, the present invention relates to using genes, proteins and methods comprising arginase or threonine deaminase for altering the pathophysiology of plants, arthropods and microorganisms. In a preferred embodiment, the present invention relates to altering guanidino substrate hydrolysis activity in plants, arthropods, and microorganisms using arginase.
