Vedclass · Answer

(D) $Agrobacterium$ $tumefaciens$ is a soil-inhabiting,plant-pathogenic bacterium that infects broad-leaved crops such as tomato,soybean,sunflower,and cotton,but it does not infect cereals.Tumor formation (crown galls) is induced by the transfer of its $Ti$ plasmid $DNA$ into the host plant's genome.The $T-DNA$ segment of the $Ti$ plasmid is responsible for tumor induction.Because this gene transfer occurs naturally without human intervention,the bacterium is known as the 'natural genetic engineer' of plants.Since the Assertion incorrectly states that it is associated with all cereal and pulse crops,and the Reason is also factually incorrect regarding the mechanism of gene transfer (it uses $Ti$ plasmid,not the chromosomal genome),both statements are incorrect.
