COPY NUMBER VARIANT LEADING TO VIRUS RESISTANCE.

摘要

The present invention relates to a genetic determinant comprising at least two copies of a combination of two closely linked RDR1 genes, which two closely linked RDR1 genes are inversely oriented, and which genetic determinant leads to virus resistance when present in a plant. In one embodiment, of the RDR1 genes in the combination is represented by SEQ ID No. 1 or has a sequence identity of at least 70% thereto, and one of the RDR1 genes in the combination is represented by SEQ ID No. 3 or has a sequence identity of at least 70% thereto; or one of the RDR1 genes in the combination encodes a protein represented by SEQ ID No. 2 or a protein that has a sequence identity of at least 70% thereto, and one of the RDR1 genes encodes a protein represented by SEQ ID No. 4 or a protein that has a sequence identity of at least 70% thereto.
