Solution

RNAi technique is helpful in preventing nematode infestation in tobacco plants. This can be done by introducing nematode-specific genes in host plants using the Agrobacterium vector in such a way that it produces both sense and antisense RNAs in the host cells. Presence of the dsRNA formed of sense and antisense strands starts the process of RNAi and silences the specific nematode mRNA. As a result, the nematode does not survive in the transgenic host plant.
