Why Agrobacterium is considered a "natural plant genetic engineer." Discuss how its genes related to gene transfer are organized, how this allows it to survive in the environment, and how plant biotechnologists have modified it to transfer genes of interest to agriculture.
What is gene silencing? How can it be used to overcome virus infection in transgenic plants? Could it be possible to make a plant resistant to a virus by using gene editing technology such as CRISPR-Cas9? Which one, siRNA or gene editing technology, would you prefer and why?
