Patent ID: 8148601

Claim:
A method for determining whether a test plant has field resistance to blast, said method comprising the following steps: (a) preparing a DNA sample from the test plant; (b) amplifying a portion of the DNA sample, wherein the portion is selected from the group consisting of: (i) a DNA that encodes a protein comprising the amino acid sequence of SEQ ID NO: 3 or 22; (ii) a DNA comprising the coding region of the nucleotide sequence of SEQ ID NO: 1, 2, 20, or 21; (iii) a DNA encoding a protein which comprises an amino acid sequence 90% or more identity to the amino acid sequence of SEQ ID NO: 3 or 22, and which has the function of a protein comprising the amino acid sequence of SEQ ID NO: 3 or 22; (iv) a DNA that encodes a protein comprising the amino acid sequence of SEQ ID NO: 6; (v) a DNA comprising the coding region of the nucleotide sequence of SEQ ID NO: 4 or 5; and (vi) a DNA encoding a protein which comprises an amino acid sequence with 90% or more identity to the amino acid sequence of SEQ ID NO: 6, and which has the function of a protein comprising the amino acid sequence of SEQ ID NO: 6; and (c) comparing the amplified DNA with the DNA of (iv) or (v) to determine whether the test plant has field resistance to blast.
