A Cloning Vector that Works with Plant Cells. Why?

1.	A Cloning Vector that Works with Plant Cells. Why?
Answer» Most commonly used plant cloning vector "Ti" plasmid, or tumor-inducing plasmid. Found in cells of the bacterium known as Agrobacterium tumefaciens, normally lives in soil. Bacterium has ability to infect plants and cause a crown gall, or tumorous lump, to form at the site of infection. Ti plasmid - called T DNA - separates from the plasmid and incorporates into the host cell genome. This aspect of Ti plasmid function has made it useful as a plant cloning vector (natural genetic engineer).
