Dear student,

Solution to your asked query is provided below:

Ti- Plasmid (Tumor-inducing plasmid) - It is a covalently closed circular DNA molecule present inside Agrobacterium tumefaciens which is responsible for the production of tumor in the plant which it infects. 
It is used in biotechnology as a cloning vector by removing the tumor-inducing genes from it. It is used to insert a foreign gene of interest in the target DNA.

Hope this information clears your doubt.
