What is the role of the Ti plasmid in Agrobacterium tumefaciens?
- Initiating the infection of the plant at the wound site
- Producing auxin and cytokinin for plant cell proliferation
- Enabling the transfer of the T-DNA region into the plant cell (correct)
- Breaking down opines and agropines as an energy source
Why does Agrobacterium tumefaciens cause crown gall formation in plants?
Why does Agrobacterium tumefaciens cause crown gall formation in plants?
- By inducing mutations in plant cell DNA
- By inhibiting photosynthesis in the host plant
- By releasing chemicals that attract it to the plant wound site (correct)
- By producing toxins that damage plant cells
What is the unique aspect of gene transfer involving Agrobacterium species into plants?
What is the unique aspect of gene transfer involving Agrobacterium species into plants?
- It happens through an exchange of RNA molecules
- It involves the transfer of bacterial genes into the plant genome (correct)
- The transfer occurs intracellularly
- The transfer leads to the production of toxins in the plant
