When the nematode infects the roots of tobacco plants and feeds upon cells containing RNAi gene. This DNA produced both sense and anti-sense RNA in the host cells (tobacco plant) and is complementary to the functional mRNA of the nematode. This complementarity between both RNA makes it double stranded and, hence silenced by not being translated into protein. Interference with RNA expression and protein synthesis makes it difficult for the pathogen to survive in tobacco plants and hence killed. In this way RNA interference protects and control the nematode infection.
How did the process of RNA interference help to control the nematode from infecting the roots of tobacco plants.
