Question

How are transgenic Tobacco plants produced to solve the parasitic attacks on the tobacco plants?

Answer 1

Transgenic tobacco plant was protected from the parasite by a process based on RNA interference, which is possessed by all eukaryotic organism as a method of cellular defense. There is a nematode-specific gene which is very important for the parasite. These genes were introduced into the tobacco plant through a vector called Agrobacterium tumefaciens. When parasite infests the tobacco plant, sense and antisense RNA in the host cell is produced, which eventually results in the silencing of mRNA of the parasite by initiating RNA interference. So no translation will occur and the parasite will not be able to survive.
