Stages of Biotechnology Development Ancient biotechnology Ancient biotechnology early history as related to food and shelter; Includes domestication Classical biotechnology Classical biotechnology built on ancient biotechnology; Fermentation promoted food production, and medicine Modern biotechnology Modern biotechnology manipulates genetic information in organism; Genetic engineering

 Traditional/old biotechnology The conventional techniques that have been used to produce beer, wine, cheese, many other food  New/modern biotechnology All methods of genetic modification by recombinant DNA and cell fusion techniques, together with the modern development of traditional biotechnological process Stages of Biotechnology Development

TRADITIONAL PLANT BIOTECHNOLOGY breeding tissue culture inter-specific hybridisation mapping phenotypic/biochemical markers

Now use a molecular approach to manipulation: molecular markers & mapping gene cloning plant transformation PLANT BIOTECHNOLOGY a process to produce a genetically modified plant by removing genetic information from an organism, manipulating it in the laboratory and then transferring it into a plant to change certain of its characteristics.

Exogenous genes (non-plant genes) Applications: transgenic pathogen-derived genes bacterial genes any other organism Pathogen resistance Herbicide resistance bioreactors Delivery systems

Endogenous genes (Plant genes ) Gene discovery (functional genomics) Applications: markers transgenic Enzymes in biochemical pathway Natural resistance genes Marker assisted breeding Plant improvement Mapping ESTs, libraries Silencing, expression Mutants, arrays
