Explain the role of Ti plasmids in biotechnology.

Explanation

The Ti plasmid (Tumour inducing Plasmid) of Agrobacterium tumefaciens has been modified and used as a cloning vector. The Ti plasmid integrates a Segment of its DNA, termed tDNA, into the chromosomal DNA of its host plant cells. The tDNA plasmid causes tumours.
AS gene transfer occurs without human effort, the bacterium is known as natural genetic engineer of Plants. Ti plasmids act as vectors to transfer foreign gene of interest in to the target plant cells.
