RNAi in nematode resistant plants Background : Certain plants have been genetically engineered to have sense-antisense gene of a parasitic nematode. The dsRNA produced by the plant then inactivates the mRNA produced in the nematode, who, then isn't able to synthesize the corresponding protein and dies as a result. Question : How is the dsRNA from the plant transfered to the nematode's cell ? By transformation ?

The question is little bit unclear: is in vitro or in vivo introduction in question?

In vivo:

> As the nematode feeds on the plant during its parasitic phase, it consequently assures the introduction of dsRNA and/or siRNA molecules into the nematode’s digestive system.

in vitro introduction etc ->
