Question

Which among the following is not a transgenic plant?

• A. Bt Cotton
• B. Golden Rice
• C. Samba Mahsuri
• D. FLAVR SAVR

Hint:

• Transgenic Plant (GMO Plant) Contains gene(s) introduced from another species using recombinant DNA technology.
• Bt Crops (e.g., Bt Cotton, Bt Corn) Express insecticidal protein from Bacillus thuringiensis.
• Golden Rice Engineered to produce beta-carotene (pro-vitamin A).
• FLAVR SAVR Tomato Engineered for delayed ripening/softening.
• Conventional breeding uses hybridization and selection within or between related species, not direct insertion of isolated genes from unrelated organisms.

Answer 1

The Correct Option is C

To determine which among the following options is not a transgenic plant, we need to evaluate each option based on the definition of a transgenic plant. A transgenic plant is one that has been genetically modified through biotechnology to contain a gene or genes from another species.

• Bt Cotton: This is indeed a transgenic plant. It has been genetically modified to express the Bacillus thuringiensis (Bt) toxin, which provides resistance to certain insect pests.
• Golden Rice: This variety of rice is also a transgenic plant. It has been genetically engineered to produce beta-carotene, a precursor of vitamin A, to address vitamin A deficiency.
• Samba Mahsuri: This is a popular high-yielding rice variety developed through traditional breeding methods, not genetic modification. Therefore, it is not a transgenic plant.
• FLAVR SAVR: This is a transgenic tomato that was engineered to have a longer shelf life by suppressing the expression of a gene that causes ripening.

As a result, the option that is not a transgenic plant is Samba Mahsuri.
