The tumour inducing capacity of Agrobacterium tumefaciens is located in large extrachromosomal plasmids called :

Assertion : Agrobacterium tumefaciens is popular in genetic engineering because this bacterium is associated with the roots of all cereal and pulse crops. Reason : A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the crop with which the bacterium is associated .

Assertion (A) : Ti plasmid (tumour-inducing plasmid) of Agrobacterium tumefaciens is used as a cloning vector. Reason (R): Ti plasmid integrates a segment of its DNA, termed T-DNA into the chromosomal DNA of its host plant cells.

Assertion : Agrobacterium tumefaciens is the causative agent of crown gall disease of dicots. Reason : Agrobacterium tumefaciens causes infection by entering the plant through wounds and injuries.
