Which vector is used for introducing nematode specific genes into the tobacco host plant.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Agrobacterium
Option (2) Agrobacterium — Correct. Agrobacterium vectors carried the nematode-specific genes.
NCERT Extract:
Biotechnological Applications in Agriculture – “… Using Agrobacterium vectors, nematode-specific genes were introduced into the host plant (Figure 10.2). The introduction of DNA was such that it produced both sense and anti-sense RNA in the host cells. These two RNA’s being complementary to each other formed a double stranded (dsRNA) that initiated RNAi and thus, silenced the specific mRNA of the nematode.”
