An important vector for the manipulation of plant genes comes from the bacterium Agrobacterium tumefaciens and is called
A) an EcoRI plasmid.
B) $\lambda$ (lambda) bacteriophage.
C) BamHI.
D) a Ti plasmid.
E) an ori.

Question

Quizplus · Accepted Answer

The Ti (tumor-inducing) plasmid is a natural vector used by Agrobacterium tumefaciens to transfer genes into plant cells. It contains specific DNA sequences called T-DNA, which are transferred to the plant genome and cause the formation of a tumor or gall. Researchers have engineered Ti plasmids to contain foreign genes of interest and use them for plant transformation. Therefore, the Ti plasmid is an important vector for the manipulation of plant genes.
