name the vector used for introducing the nematode specific genes in tobacco plant?
what happens when meloidegyne incognitia consume cells with RNAi genes?
Ans a) Nematode-specific genes are introduced into the tobacco plants using Agrobacterium vectors to develop resistance in tobacco plants against nematodes.
Ans b) When Meloidogyne incognita (parasite) consumes cells with RNAi gene, parasite cannot
survive and this prevents infestation. The introduced RNAi gene DNA forms both sense
and anti-sense RNA. Two strands being complementary to each other bind and form ds
RNA which cannot be translated, leading to RNAi. Thus, the mRNA of nematode is silenced and the parasite cannot
survive there.
