Which of the following is false for BT transgenic plant

Options

A. Disease resistance
B. Prepared by Bacillus thuringiensis
C. It is recombinant type
D. No such plant is known

Explanation

To determine which statement is false regarding BT transgenic plants, we will analyze each statement provided in the options.

**Step 1: Understand BT Transgenic Plants**
- BT transgenic plants, such as BT cotton, are genetically modified to express a protein from the bacterium Bacillus thuringiensis (BT). This protein is toxic to certain pests, providing the plant with insect resistance.

**Step 2: Evaluate the Statements**
- We will evaluate each statement one by one to identify which one is false.

**Statement A: "BT transgenic plants are disease resistant."**
- This statement is true. BT transgenic plants are engineered to resist certain insect pests due to the presence of the cry gene from Bacillus thuringiensis, which produces a protein harmful to these pests.

**Statement B: "BT transgenic plants are prepared by Bacillus thuringiensis."**
- This statement is also true. The process of creating BT transgenic plants involves using genes from Bacillus thuringiensis.

**Statement C: "BT transgenic plants are recombinant types."**
- This statement is true as well. BT transgenic plants are indeed recombinant organisms because they contain DNA from another species (Bacillus thuringiensis).

**Statement D: "No such plant is known."**
- This statement is false. BT transgenic plants, such as BT cotton, are well-known and widely cultivated.

**Step 3: Conclusion**
- The false statement regarding BT transgenic plants is **Statement D: "No such plant is known."**

Thus, the answer to the question is Statement D.
