What is the main strategy adopted to prevent infestation of tobacco plants by nematodes?

Options

  1. AReplication of mobile genetic elements
  2. BRNA interference
  3. CInfection by viruses
  4. DUse of chemical pesticides

Correct answer

B. RNA interference

Step-by-step solution

Pest Resistant Plants: Several nematodes parasitise a wide variety of plants and animals including human beings. A nematode Meloidegyne incognitia infects the roots of tobacco plants and causes a great reduction in yield. A novel strategy was adopted to prevent this infestation which was based on the process of RNA interference (RNAi) . RNAi takes place in all eukaryotic organisms as a method of cellular defense. This method involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to a
