The grape canker resistance related protein disclosed by the invention is A1) or A2): A1) a protein with an amino acid sequence of sequence 2; a2) a protein which is obtained by substitution and/or deletion and/or addition of one or more amino acid residues on the amino acid sequence shown in the sequence 2 in the sequence table and has the same function as the protein shown in the sequence 2. Experiments prove that the resistance of plants (such as tobacco or grapes) to the grape canker can be remarkably improved through expression of the grape canker resistance related protein.
