Correct option:(B)of its ability to insert Ti plasmid into nuclear genome
Solution:
- Agrobacterium tumefaciens naturally infects the wound sites in dicots causing the crown gall disease.
- It is capable of transferring T-DNA of the Tumour inducing (Ti) plasmid into the nucleus of infected cells.
- It will then integrate into the host genome and is transcribed, causing the crown gall disease.
- Property of tumor formation is exploited in biotechnology.
- So, Agrobacterium tumefaciens has become the most used method for plant transformation by gene transfer.
