A method of using a tospoviral nucleic acid molecule of the sequence of nt
(nucleotide) 3975-4928 in accordance with GenBank Accession No. AF133128
or a full complement thereof comprising the steps of: (a) obtaining at
least one fragment made from the tospoviral nucleic acid molecule; (b)
obtaining a transgene from the at least one fragment; (c) introducing the
transgene into a plant to generate a transgenic plant; (d) culturing the
transgenic plant; (e) selecting a transgenic plant with broad-spectrum
resistance; and (f) obtaining the transgenic plant with broad-spectrum
resistance.
