Question

How has the use of \textit{Agrobacterium as vector helped in controlling \textit{Meloidogyne incognita} infestation in tobacco plants? Explain in correct sequence.}

Hint:

RNA interference (RNAi) is a biotechnological tool that uses double-stranded RNA to silence specific genes, providing resistance against pests like nematodes.

Answer 1

A nematode-specific gene is introduced into the tobacco plant using \textit{Agrobacterium tumefaciens}. The plant produces double-stranded RNA (dsRNA), initiating RNA interference (RNAi). RNAi silences the vital genes of \textit{Meloidogyne incognita}, reducing infestation and damage.
