How does RNA interference help in developing resistance in tobacco plant against nematode infection?
✓

Answer

With RNA interference (RNAi) technique transgenic tobacco plant is protected against nematode/Meloidegyne incognitia using Agrobacterium as the vectors, nematode-specific genes were introduced into the host plant, it produces both sense & anti sense RNA, these 2 RNAs form ds RNA, it silences specific mRNA of nematode (no protein synthesis/no translation ), hence nematode cannot survive in tobacco plant.
