Assertion: RNAi helps protect tobacco plants from the root-knot nematode Meloidogyne incognita.
Reason: RNAi occurs in eukaryotes as a cellular defense mechanism.
However, the prevention of infestation is specifically due to silencing of essential nematode genes by dsRNA produced in the transgenic plant, not merely because RNAi is a defense mechanism.
