| Description: A Ti plasmid carrying a foreign gene is inserted into an Agrobacterium tumefaciens bacterium. B The bacterium infects a plant cell and transfers the Ti plasmid into it. The plasmid DNA becomes integrated into one of the cell’s chromosomes. C The plant cell divides, and its descendants form an embryo. Several embryos are sprouting from this mass of cells. D Each embryo develops into a transgenic plant that expresses the foreign gene. The glowing tobacco plant is expressing a gene from fireflies.
