Question

Why could parasite not survive in a transgenic tobacco plant?

Answer 1

As transgenic tobacco plants express genes unique to nematodes, parasites may not be able to live there. These genes may produce RNAs or proteins that interfere with the parasite's growth, life cycle, or capacity to infect plants. Additionally, transgenic tobacco plants may exhibit enhanced resistance mechanisms, such as alterations in cell wall composition or increased synthesis of defensive chemicals, which might obstruct parasite infection and survival.
