What is the role of Agrobacterium vectors in preventing nematode infestation?

Options

  1. ATo introduce specific genes
  2. BTo initiate RNAi
  3. CTo produce dsRNA
  4. DTo silence specific mRNA

Correct answer

A. To introduce specific genes

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 an
