Question

Quizplus · Accepted Answer

Agrobacterium species contain the Ti (tumor-inducing) plasmid that allows them to transfer genes to plant cells, causing the development of tumors and modifying the growth of plant tissue. This mechanism has been exploited for genetic engineering in plants. Agrobacterium species do not produce antibiotics, infect animal cells, resemble fungus, or fix nitrogen.
