Nematodes

Vedclass · Answer

(C) $RNA$ interference $(RNAi)$ is a cellular mechanism used to silence specific genes. In biotechnology,this technique is employed to protect plants from parasitic infestations. Specifically,the nematode $Meloidogyne$ $incognita$ infects the roots of tobacco plants. By introducing nematode-specific genes into the host plant using $Agrobacterium$ vectors,double-stranded $RNA$ $(dsRNA)$ is produced. This $dsRNA$ initiates $RNAi$,which silences the essential genes of the nematode,thereby preventing the parasite from surviving in the transgenic host plant.

$RNA$ interference $(RNAi)$ is used to produce transgenic plants resistant to which of the following?
