Solution
Nematode-specific DNA is introduced into tobacco using Agrobacterium. The plant produces complementary sense and antisense RNAs that form double-stranded RNA. When the nematode feeds, this triggers RNA interference and silences an essential nematode mRNA, preventing the parasite from surviving.
