What is a common method of gene transfer in plants?

• A. Bacterial infection via Agrobacterium
• B. Agrobacterium-mediated transformation
• C. Electroporation
• D. Microinjection

Answer: (B)

Agrobacterium-mediated transformation is a widely utilized method for gene transfer in plants. This technique leverages the natural ability of the bacterium Agrobacterium tumefaciens to transfer a part of its DNA, known as T-DNA, into the plant genome. This process typically occurs during the infection of the plant by Agrobacterium, which induces tumor formation; however, scientists have harnessed this capability to introduce desired genes into the plant's chromosomes for purposes such as improving crop traits, resistance to pests, or enhancing nutritional value. The appeal of this method lies in its efficiency and specificity. Agrobacterium is capable of infecting a wide range of plant species, making it versatile for transforming various crops. Additionally, the method often leads to stable integration of the introduced genetic material, ensuring that the modifications are heritable across generations. Other methods like electroporation and microinjection are more common in animal cells but less effective and efficient in plants due to their rigid cell walls. Therefore, Agrobacterium-mediated transformation remains the most prominent and well-established technique for gene transfer in the field of plant biotechnology.
