Step 1: Production of signal molecules form wounded plant cell; Step 2: Recognition of signal molecules by bacterial receptors; Step 3: Attachment of Agrobacterium to plant cell; Step 4: Activation of Vir proteins which process ss-TDNA; Step 5: Formation of immature T-complex; Step 6: T-DNA transfer; Step 7: Assembly of mature T-complex and Nuclear transport; Step 8: Random T-DNA integration in the plant genome; Step 9: Expression of bacterial genes and synthesis of bacterial proteins.
