DNA comprising SEQ ID NO:

• 1 or a DNA that hybridizes to SEQ ID NO:
• 1 under stringent hybridization conditions, said DNA that hybridizes to SEQ ID NO:
• 1, 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.

DNA comprising SEQ ID NO:

• 5 or a DNA that hybridizes to SEQ ID NO:
• 5 under stringent hybridization conditions, said DNA that hybridizes to SEQ ID NO:
• 5, 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.

Isolated DNA selected from the group consisting of SEQ ID NOS:
