Explain nematode specific plant step melatogonia intogoeina

Expert Answer:

Pest Resistance in Transgenic Plants:
  • The nematode Meloidogyne incognita infects the roots of tobacco plants and causes a reduction in yield.
  • A unique strategy based on RNA interference (RNAi) was designed by Fire and Mello in 1998. This method involves silencing of a specific mRNA.
  • Using Agrobacteriumvectors, nematode-specific genes were introduced into the host plant. The introduction of DNA produced both sense and anti-sense RNA in the host cells.
  • These two RNAs being complementary to each other formed a dsRNA which initiated RNAi.

  • When the mRNA of the parasitewasdestroyed, no protein was synthesised.
  • This resultedin the death of the parasitic nematode in the transgenic host.
  • In this way, the transgenic plant got itself protected from theparasite.
