In the field of plant transgenics, the use of the bacterium Agrobacterium tumefaciens has proven useful because:
A) it is not attacked by plant immune systems.
B) it has been genetically engineered to penetrate the plant cell wall.
C) it can directly modify the plant genome, causing it to make useful products for humans.
D) it is found naturally in almost all species of plants.
E) it is able to transfer a plasmid into host plant cells.

Question

Quizplus · Accepted Answer

Agrobacterium tumefaciens is used in plant transgenics because it can transfer a plasmid (T-DNA) into host plant cells, which integrates into the plant genome, allowing for genetic modification.
