1.	The Tumour inducing (Ti) plasmid of which plant pathogen has been modified into a cloning vector to deliver genes of our interest? (a) Providencia stuartii (b) Agrobacterium tumefaciens (c) Haemophilus haemolyticus (d) Bacillus globigii
Answer» Answer : (b) Agrobacterium tumefaciens Agrobacterium tumefaciens, a pathogen of several dicot plants is able to deliver a piece of DNA, known as T-DNA, to transform normal plant cells into a tumour cell and direct these tumour cells to produce the chemicals required by the pathogen. The Ti plasmid of Agrobacterium tumefaciens has now been modified into a cloning vector which is no more pathogenic to the plants. It is able to deliver the genes of our interest into a variety of plants.
