Pest resistant plants: (a) A nematode meloidegyne incognitia infects the roots of tobacco. Plant which reduce the production of tobacco.
(b) It can be prevented by using RNA/Process which is checked by silencing of specific m RNA due to complementary ds RNA.
(c) By using Agrobacterium vector's nematode specific genes were introduced into the host plant which produce sense & antisense RNA in hose cells. The Parasite cannot survive on the transgenic hos in protect the plants from pest.
