As a plant biologist for Monsanto, Robert Horsch and two other colleagues published a paper about a soil bacterium, Agrobacterium tumefaciens, that detailed its natural genetic engineering abilities.

Robert Horsch explains the mechanism by which agrobacterium delivers its DNA "parcel."
Robert Horsch talks about agrobacterium as a ready-made delivery system for getting foreign DNA into plants.
Robert Horsch compares the random power of a gene gun with the natural genetic engineering abilities of agrobacterium.
Robert Horsch talks about the parasitic nature of agrobacterium and the effect it has on the host plant.
Robert Horsch talks about the gene gun: a physical method of delivering genes into plant cells.
Renowned biologist and philosopher Robert Pollack reflects on his concern over the potential danger of Janet Mertz's experiment inserting a cancer-causing gene from a monkey virus into a bacterium that lives in humans.
Paul Berg's student, Janet Mertz, planned an experiment that would recombine DNA from a monkey virus with DNA from a bacterium that lives in the human gut. Berg describes colleague Bob Pollack's outrage at this.

Joshua Lederberg worked with bacterial genetics while Alfred Hershey showed that DNA is responsible for the reproduction of new viruses in a cell.
