5. Manipulating plants for the benefit of mankind
PLANT BIOTECHNOLOGY
Manipulating plants for the benefit of mankind
Traditionally
breeding
tissue culture
inter-specific hybridisation
mapping phenotypic/biochemical markers

6. 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 .
Now use a molecular approach to manipulation:
molecular markers & mapping
gene cloning, sequencing
plant transformation
genetic manipulation - transfer, silencing, up-regulation

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

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