Question

Identify the wrong statement from the following:

• A. Bt. Cotton shows resistance to viruses.
• B. Transgenic Potato shows resistance to it{Phytophthora}.
• C. Transgenic Papaya shows resistance to Ring Spot Virus.
• D. Transgenic Tomato shows resistance to it{Pseudomonas}.

Hint:

Genetically modified (GM) crops are designed for specific resistance. Always verify the exact pathogen targeted in the modification process.

Answer 1

The Correct Option is B

The incorrect statement is (1) Bt. Cotton shows resistance to viruses. 
Explanation:
Bt Cotton: Bt cotton is genetically modified to produce a toxin from the bacterium Bacillus thuringiensis. This toxin is specifically effective against certain insects, particularly lepidopteran pests (like bollworms), not viruses.
The other statements are correct:
Transgenic Potato: Late blight disease in potatoes is caused by the oomycete Phytophthora infestans. Transgenic potatoes have been developed with resistance genes to combat this disease.
Transgenic Papaya: Papaya ringspot virus is a major threat to papaya cultivation. Genetically modified papaya varieties have been successful in resisting this virus.
Transgenic Tomato: Bacterial wilt caused by Pseudomonas solanacearum can be devastating to tomato crops. Transgenic approaches have been used to introduce resistance against this bacterium.
