Step-by-step solution
Agrobacterium tumefaciens is widely known as the natural genetic engineer of plants because of its inherent ability to transfer genes into plant genomes. T-DNA is the specific piece of DNA from the Ti plasmid that is delivered and integrated into the host plant genome to transform normal cells into a tumor. The Ti plasmid is the tumor-inducing plasmid found naturally in the bacterium. A disarmed vector is a modified cloning vector (like the modified Ti plasmid) from which the pathogenic (tumor-inducing) genes have
