Question

RNA interference is used for which of the following purposes in the field of biotechnology?

• A. to develop a plant tolerant to abiotic stresses
• B. to develop a pest resistant plant against infestation by nematode
• C. to enhance the mineral usage by the plant
• D. to reduce post-harvest losses

Answer 1

The correct option is B to develop a pest resistant plant against infestation by nematode

The nematode Meloidogyne incognita, infects the roots of the tobacco plant and creates knot-like structures in the root. These knot-like structures affect efficient functioning of the roots and decrease the yield of the plant.

The scientists adopted a unique strategy to prevent this infestation which was based on the process of RNA interference (RNAi). RNAi involves silencing of a specific mRNA.

Hence, RNA interference is used to develop a pest resistant plant against infestation by nematode.
