$RNAi$ or $RNA$ interference or anti-sense $RNA$ is a naturally occurring mechanism that leads to the “silencing” of genes. In consequence, the respective protein is no longer synthesized. Several nematodes parasitize a wide variety of plants. A nematode Meloidogyne incognita infects the roots of tobacco plants causing a great reduction in yield. The most \cos t-effective and sustainable management tactic for preventing such damage is by using $RNAi$ mechanism by developing genetically engineered or transgenic plants.
