How does a ti plasmid work?

The ti plasmid (tumor-inducing) is associated with the soil bacterium species Agrobacterium tumefaciens. It has typical bacterial plasmid features that allow for replication of the plasmid and expression of genes with bacterial regulatory sequences. It also has regions that can be mobilized from the bacterium when it infects a wound site on a plant. The DNA called T-DNA is transferred to a plant cell where it is integrated into the plant genome and encodes genes that are expressed in the plant and cause the plant cell to alter its developmental program.
