The exapmles of transgenic plants are all, except:

Options

A. Bt tobacco
B. Golden rice was designed to produce ` beta ` - carotence in the endospen part
C. Brassica napus with hirudin gene
D. Pentadiplandra brazzeana

Answer

To determine which of the following options is not an example of a transgenic plant, we need to analyze each option provided:

1. **Bt Tobacco**: This is a transgenic plant that has been genetically modified to express a protein from the bacterium *Bacillus thuringiensis*. This protein acts as an insecticide, making the plant resistant to certain pests. Therefore, Bt Tobacco is indeed a transgenic plant.

2. **Golden Rice**: This is another well-known transgenic plant. It has been genetically engineered to produce beta-carotene, a precursor of vitamin A, in its endosperm. This modification aims to combat vitamin A deficiency in populations that rely heavily on rice as a staple food. Thus, Golden Rice is also a transgenic plant.

3. **Brassica napus with Herodin gene**: Brassica napus, commonly known as rapeseed or canola, has been modified to express the Herodin gene, which has anticoagulant properties. This modification is aimed at producing plants that can potentially provide health benefits. Therefore, this is also a transgenic plant.

4. **Penta diplandra braziana**: This is an evergreen shrub that produces red berries. There is no indication that this plant has been genetically modified or altered in any way to produce specific traits. Hence, it is not classified as a transgenic plant.

Based on the analysis above, the correct answer is **Penta diplandra braziana**, as it is not a transgenic plant.

### Final Answer:
The example of a transgenic plant is all, except: **Penta diplandra braziana**.
