Explain how to produce a nematode-resistant transgenic plant.
The nematode named Meloidogyne incognita infects tobacco plants and reduces the yields of that plant. The specific parasite genes are introduced into plants using the Agrobacterium vector. The genes are introduced to produce both sense and antisense RNA. Then the formation of double-stranded RNA (ds RNA) occurs since these two RNAs are complementary. It neutralizes certain nematode RNA by a process called RNA interference, resulting in the inability of the parasite to live in the transformed host. In this way, the plant is protected from pests.
