Impartment of virus-resistance with the use of plant protein binding to plant virus transport protein

摘要

A method for conferring resistance to a plant virus to plants is provided. The method comprises the step of introducing into cells of the plant a polynucleotide encoding a protein capable of binding to a movement protein of the plant virus. In one embodiment, the protein encoded by the polynucleotide contains a sequence indicated by position 1 to 86 of SEQ ID NO. 2, or contains the sequence having one or several amino acid substitutions, deletions, and/or additions, and binds to the movement protein of the plant virus. In one embodiment, the polynucleotide contains a nucleotide sequence indicated by position 14 to 271 of SEQ ID NO. 1 or a nucleotide sequence hybridizable to that nucleotide sequence under stringent conditions.
