Tobacco plant resistant to a nematode have been developed by the introduction of DNA that produces

Step-by-step solution

Using Agrobacterium vectors, nematode-specific genes were introduced into the host plant . The introduction of DNA was such that it produced both sense and antisense RNA in the host cells. These two RNA’s being complementary to each other formed a double stranded (dsRNA) that initiated RNAi and thus, silenced the specific mRNA of the nematode. The consequence was that the parasite could not survive in a transgenic host expressing specific interfering RNA. The transgenic plant therefore got itself protected from t
