Agrobacterium - a natural genetic engineer of plants justify the statements.

Explanation

Among the various used for plant transformation , the plasmid from Agrobacterium humefaciens has been used extensively. This bacterium has a large size plasmid , known as The plasmid ( Tumor inducing ) and a portion of it referred as T - DNA ( transfer DNA ) is transferred to plant genome in the infected cells and cause plant tumors ( crown gall). Since this bacterium has the natural ability to transfer T - DNA region of its plasmid into plant genome. Upon infection of cells at the wound site , it is also known as the natural genetic engineer of plants .
