Question

nematode specific genes were introduced into the tobacco host plant using a vector?​

Answer 1

Answer:

Agrobacterium vectors

Explanation:

By using Agrobacterium vectors, nematode-specific genes were introduced into the host plants which produce both sense and antisense RNA in the host cells. These two RNAs are complementary to each other and form a double stranded RNA (ds RNA) that initiates RNAi and hence, silences the specific mRNA of the nematode.
