Question
Why is Agrobacterium-mediated genetic transformation described as natural genetic engineering in plants?
✓
Answer
Agrobacterium tumifaciens is a pathogen of several dicot plants which exhibit natural genetic engineering in plant.
Reasons:
- It is able to deliver a piece of DNA called ‘T-DNA’ to transform normal plant cell into a tumour cell.
- The DNA transforms the normal cells into tumour cells which direct them to produce the chemical essential for the pathogen.
