Patent number: 11939588Abstract: 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: GrantFiled: October 15, 2020Date of Patent: March 26, 2024Assignee: Board of Trustees of Michigan State UniversityInventors: Gregg A. Howe, Qiang Guo

Publication number: 20230365987Abstract: 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.Type: ApplicationFiled: April 28, 2023Publication date: November 16, 2023Inventors: Gregg A. Howe, Marcelo Campos, Yuki Yoshida
