Lecture 40- Genetic Modification Genetically Modified Organisms (GMOs) -Have foreign and endogenous (pre-existing) genes GM Plants -GMO means a transgenic organism, which is an organism that has been transformed -Bioreactors may be used to produce drugs, plastic -Genetic engineering and even ancient forms of genetic engineering used to increase crop yield, enhance traits, pest resistance -Through hundreds of thousands of years corn, for example, has been transformed from its early forms called “teosinte” into present day corn Natural Transformation: Agrobacterium -Bacteria will infect the plant with a tumour inducing plasmid; the piece of plasmid moves into the plant cell’s DNA -The tumour is induced by the plasmid and a “crown gall” grows at the base of the plant -Anything between the left and right borders will be transferred into the cell’s DNA Making a Transgenic Plant -Plants are totipotent, meaning they can generate an entire plant from one cell 1) Chop up leaf cells and bacteria, where t-DNA is transformed into the cells
