Why are transgenic plants often created?

• A. To enhance their natural disease resistance
• B. To shorten their growth cycle
• C. To improve their aesthetic value
• D. To change their color for market appeal

Answer: (A)

Transgenic plants are commonly created to enhance their natural disease resistance. This is significant because plant diseases can cause substantial crop losses, affecting food supply stability and agricultural productivity. Genetic engineering allows scientists to introduce specific genes from other organisms that confer resistance to particular pathogens, such as bacteria, fungi, or viruses. By doing so, transgenic plants can be better equipped to withstand diseases that would otherwise compromise their growth and yield.

Improving disease resistance through genetic modification also reduces the reliance on chemical pesticides, which can have adverse environmental impacts and can lead to pesticide-resistant pests. Thus, enhancing disease resistance not only contributes to higher crop yields but also promotes more sustainable agricultural practices.

While shortening the growth cycle, improving aesthetic value, and changing color for market appeal are also valid reasons for creating transgenic plants, the primary focus in biotechnology and genetic engineering often centers on addressing critical agricultural challenges such as disease resistance.
