Ti plasmid naturally occurs in
The Ti plasmid, also known as the tumor-inducing plasmid, is a type of plasmid that is found in the bacteria Agrobacterium tumefaciens in its natural state when it is present. This particular plasmid is accountable for the transmission of genetic material from the bacteria to the plant, which ultimately results in crown gall disease. During the process of genetic engineering, scientists make use of this capability to introduce new genes into plants.
