(B) The nematode $Meloidogyne$ $incognitia$ infects the roots of tobacco plants,which significantly reduces tobacco production.This can be prevented by using the $RNA$ interference $(RNAi)$ process.In this process,by using an $Agrobacterium$ vector,nematode-specific genes are introduced into the host plant.These genes produce both sense and antisense $RNA$ in the host cells,which form double-stranded $RNA$ $(dsRNA)$.This $dsRNA$ initiates $RNAi$,which silences the specific $mRNA$ of the nematode,thereby preventing its survival in the host plant.

Tobacco plants resistant to a nematode have been developed by the introduction of $DNA$ that produces (in the host cells):
