AGENT FOR IMPARTING RESISTANCE TO FEEDING DAMAGE BY PHYTOPHAGOUS ARTHROPOD (As Amended)

摘要

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.

主权项

1. An agent for imparting resistance to feeding damage by a phytophagous arthropod, comprising a polypeptide represented by any of the following amino acid sequences (a) to (c) or an active fragment thereof:
(a) a polypeptide in which proline (P) at position 234 in the amino acid sequence shown in SEQ ID NO: 1 is substituted by leucine (L), (b) a polypeptide comprising an amino acid sequence derived from the polypeptide (a) by the deletion, substitution, or addition of one or several amino acids except for leucine at position 234, and (c) a polypeptide having 60% or more amino acid identity to the polypeptide (a).
