  • Publication number: 20160145639
    Abstract: An object of the present invention is to develop and provide a method for enhancing the resistance of a plant itself to feeding damage by a phytophagous arthropod. A gene expression system containing, in an expressible state, a gene encoding a variant BIL1/BZR1 protein with a particular point mutation is transferred to a desired plant to thereby impart resistance to feeding damage by a phytophagous arthropod to the plant.
