In using Agrobacterium tumefaciens to transfer genes into plants, the T-DNA (transfer DNA) is transferred from the bacterium to the plant. The T-DNA is part of the Ti (tumor-inducing) plasmid in the bacterium and is responsible for causing the formation of a tumor or gall on the infected plant. However, researchers have modified the Ti plasmid to remove the tumor-causing genes and replace them with desired genes for plant transformation.
