1. DNA comprising a combination of fragment A linked directly or indirectly to fragment B, wherein:

  • fragment A consists of a double-stranded cDNA fragment derived from the RNA of the plum pox virus; and

    fragment B consists of a double-stranded cDNA fragment derived from the S RNA of the N structural gene of the tomato spotted wilt virus;

    said combination, when expressed in a plant, conferring on said plant an increased resistance, as compared to a natural plant of the same species, to tomato spotted wilt virus and another tospovirus.
