With reference to the Genetically Modified mustard (GM mustard) developed in India, consider the following statements:
1. GM mustard has the genes of a soil bacterium that give the plant the property of pest-resistance to a wide variety of pests.
2. GM mustard has the genes that allow the plant cross-pollination and hybridization.
3. GM mustard has been developed jointly by the IARI and Punjab Agricultural University.
Which of the statements given above is/are correct?
A
1 and 3 only
B
2 only
C
2 and 3 only
D
1, 2 and 3
Correct Answer: Option B
Explanation
1. Statement 1 is incorrect. The GM mustard variety developed in India (Dhara Mustard Hybrid-11 or DMH-11) incorporates genes (barnase and barstar) from a different soil bacterium (Bacillus amyloliquefaciens) for hybridization, not primarily for pest-resistance like the Bt gene (from Bacillus thuringiensis) used in GM cotton. It does not provide resistance to a wide variety of pests.
2. Statement 2 is correct. The primary purpose of the genetic modification in DMH-11 is to facilitate hybridization in mustard, which is generally a self-pollinating plant. The introduced genes create a male sterility and fertility restoration system, allowing for controlled cross-pollination to produce high-yielding hybrid seeds.
3. Statement 3 is incorrect. GM mustard (DMH-11) was developed by the Centre for Genetic Manipulation of Crop Plants (CGMCP) at the University of Delhi, not jointly by the IARI and Punjab Agricultural University.
