TRANSGENIC PLANTS - Transformation
TRANSFORMATION transfer of foreign genetic material from one species to another.
In nature, the bacterium Agrobacterium tumefaciens can transfer DNA (TDNA) into plant cells.
T-DNA contains genes encoding
- opine production - Opines serve as a food source for Agrobacterium
- hormone stimulation - uncontrolled growth of transformed plant tissue: crown gall disease eg. grapes, rose, peach willow
