Which of the following attacks the roots of tobacco plants causing its yield to decrease?

Options

  1. AMosquito
  2. BAphids
  3. CMeloidogyne incognita
  4. DLepidopterans

Correct answer

C. Meloidogyne incognita

Step-by-step solution

Pest Resistant Plants: Several nematodes parasitise a wide variety of plants and animals including human beings. A nematode Meloidogyne incognita 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 and
