Agrobacterium tumefaciens can form root nodules in plants and can mate with bacteria, which makes it an excellent host organism for genetic transformations among different domains of life.

Question

Quizplus · Accepted Answer

Agrobacterium tumefaciens is known for causing crown gall disease in plants by transferring part of its DNA to the plant cells, leading to tumor formation, not root nodules. Root nodules are typically formed by nitrogen-fixing bacteria such as Rhizobium species in legumes. While Agrobacterium tumefaciens is widely used for genetic transformations in plants, the statement about forming root nodules and mating with bacteria to facilitate transformations across different domains of life is inaccurate.
