As we learned in the last video, nitrogen-fixing bacteria are key to all life. It makes sense, then, that plants have evolved symbiotic relationships with nitrogen-fixing bacteriods. But how does that work? What genes are involved?
Even cooler is the ability of Agrobacterium tumefaciens to transfer DNA into plants for its own selfish reasons. How does this plant pathogen genetically engineer plants? And why? Tune in to find out!
These videos are based on UC Berkeley's MCB/PMB C112 class (taught in Fall 2025 by Dr. Kathleen Ryan).
