First genetically modified plant commercially released in India is

Options

A. Golden rice
B. Slow ripening tomato
C. Bt brinjal
D. Bt cotton

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the first genetically modified plant that was commercially released in India.

2. **Recall Relevant Information**: The first genetically modified plant that was commercially released in India is known to be BT cotton.

3. **Explain BT Cotton**: BT cotton is a genetically modified variety of cotton that has been engineered to express a gene from the bacterium Bacillus thuringiensis (Bt).

4. **Discuss the BT Gene**: The BT gene from Bacillus thuringiensis produces proteins known as cryoproteins, which are toxic to certain pests.

5. **Mechanism of Action**: When insects feed on BT cotton, the cryoproteins enter their bodies. In the alkaline environment of the insect's midgut, these proteins become activated.

6. **Effect on Insects**: Once activated, the cryoproteins create perforations in the gut of the insect, leading to its death. This mechanism protects the BT cotton plant from pest damage.

7. **Conclusion**: Therefore, the answer to the question is BT cotton.

**Final Answer**: The first genetically modified plant commercially released in India is BT cotton.
