Expert Answer
An extra-chromosomal DNA which delivers gene of interest into a variety of plants and acts as cloning vector in the host organism is called Ti plasmid. It is present in pathogenic bacterium Agrobacterium tumefaciens. Ti plasmid vectors are used for genetic transformation in many dicot plants. The tumour inducing (Ti) plasmid of Agrobacterium tumefaciens has been modified into a cloning vector which is no more pathogenic to the plants, but is still able to use the mechanism to deliver the gene of interest into a variety of plants.
