Why is Agrobacterium tumefaciens a good cloning vector ? Explain.

Explanation

The tummer inducing plasmid of Agrobacterium tumefaciens Ti-plasmid has now been modified into a cloning vector which is no more phthogenic to the plants but is still able to use the mechanism to deliver genes of our interest into a variaty of plants.
Agrobacterium tamifaciens is a soil bacterium which causes diseases in meny dicot plants . It is able to deliver a picee of DNA known as T-DNA, to transfrom the normal cells into tumor cells and direct these tumor cells to produce to chemicals required by the pathogen.
