The strategy used to prevent the nematode infection in the roots of tobacoo plant in called:

A

use of agrochemicals

B

Bt toxin gene

C

gene mutation

D

RNA interference

Text Solution

Verified by Experts

The correct Answer is:
D
Nematode is a group of organisms which parasitise a large number of plants and animals including human beings. One of the most common nematodes (Meloidegyne incognita ) infects the roots of tobacco plants and causes a great loss by causing reduction in yield. This infectation was prevented by using a novel strategy which was based on the process of RNA interferance (RNAi )
