Agrobacterium tumefaciens

Vedclass · Answer

(C) $T-DNA$ (Transfer $DNA$) is a segment of $DNA$ found in the $Ti$ (Tumor-inducing) plasmid of the soil bacterium $Agrobacterium$ $tumefaciens$. This bacterium naturally infects plants and transfers its $T-DNA$ into the host plant genome, causing crown gall disease. In biotechnology, scientists have modified this system by removing the disease-causing genes and replacing them with genes of interest, making $Agrobacterium$ $tumefaciens$ an excellent vector for plant genetic engineering.
