Removal of the $T-DNA$ region

Vedclass · Answer

(A) The tumor-inducing $(Ti)$ plasmid of $Agrobacterium$ $tumefaciens$ is modified by removing the $T-DNA$ region,which is responsible for tumor formation in plants.This process is known as 'disarming' the plasmid.By removing the $T-DNA$ and replacing it with the gene of interest,the plasmid becomes a non-pathogenic cloning vector.It retains the ability to transfer the desired gene into plant cells using its natural $vir$ $(virulence)$ gene machinery.
