What is agrobacterium?, Robert Horsch

Description:
Interviewee: Robert Horsch. Robert Horsch talks about the parasitic nature of agrobacterium and the effect it has on the host plant. (DNAi Location: Manipulation > Techniques > Transferring & storing > Interviews > What is agrobacterium?)
Transcript:
Agrobacterium is amazing little bacteria that is found in soil almost everywhere in the world and that makes its living in nature by genetically engineering live cells in a wounded part of a plant. It will splash in or blow in on dust particles, and when it finds a wound it will attach to the cell wall and transfer a segment of DNA that contains genes that do two things: the first are a set of genes that cause the plant cells to grow into this gall, and that creates a physical home, it's full of little nooks and crannies that the bacterial colonies can grow and protect it from the weather. It also tells the plant cells to make a unique set of compounds called opines that are nitrogen-rich, which is an essential rare nutrient in nature, and have sugar, an energy and carbon source.
