Why could parasite not survive in a transgenie tobacco plant?

Ans. Parasites may not survive in a transgenic tobacco plant due to the expression of nematode-specific genes introduced into the plant. These genes may produce proteins or RNAs that interfere with the parasite’s lifecycle, development, or ability to infect the plant. Additionally, transgenic tobacco plants may exhibit enhanced resistance mechanisms, such as altered cell wall composition or increased production of defensive compounds, which can inhibit parasite infection and survival.
