How has Agrobacterium tumefaciens been suitably modified to act as a cloning vector?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Agrobacterium tumefaciens**: Agrobacterium tumefaciens is a bacterium known for its ability to induce tumors in plants through the transfer of DNA from its plasmid into the plant cells. 2. **Role of Ti Plasmid**: The Ti (tumor-inducing) plasmid present in Agrobacterium tumefaciens is responsible for this pathogenicity. It carries genes that facilitate the transfer of DNA into the plant genome, leading to tumor formation. 3. **Modification of Ti Plasmid**: To use Agrobacterium tumefaciens as a cloning vector, the Ti plasmid must be modified. This involves "disarming" the Ti plasmid, which means removing or deleting the genes responsible for its pathogenic effects. ...
