Agrobacterium contain the Ti plamisd which modifies the growth of plant tissue

Explanation:

Agrobacterium is a gram-negative bacteria which contain Ti plasmid which modifies the growth of plant tissue as a result from modifying DNA of plants by transference ( T-DNA) dysregulation cells division.  When plants are infected whit agrobacterium,  they presents alterations and dysregulation in the metabolism of their byologic regulators called phytoregulators and will start to synthesize opinas,  and all of the above triggers cell dysregulation and cells division resulting in the production of tumors.
