PLANTS TRANSFORMATION
Week 7
INTRODUCTION
Plants Transformation
• the introduction of foreign genes into plant cells
and the subsequent regeneration of
transgenic plants
• In nature, usually mediated (perantaran) by
Agrobacterium tumefaciens, a soil plant
pathogenic bacterium.

plant transformation, Electronic journal of Biotechnology, Vol. 1, (3).

formation
of the crown gall tumors
Formation of Crown Gall Tumor
• tumor formation may be a result of the gene
transfer from A. tumefacien to infected plant
cells.
• ability to transfer a particular DNA segment
(T-DNA) of the tumor-inducing (Ti) plasmid
into the nucleus of infected cells where it is
then stably integrated into the host genome
and transcribed, causing the crown gall
disease.
Questions for Assignment
1. Illustrate mechanism of tumor induction by
A. tumefaciens related to T-DNA transfer.
2. What are the beneficial uses of Plant
Transformation in Plant Biotechnology.
3. Establish an example of the concept of plant
transformation towards development of
transgenic plant through genetic engineering.
Questions for Assignment
4. Propose modification of steps in methodology
of performing plant transformation among
monocotyledon.
5. Establish steps in plant micropropagation
starting from explant selection until
aclimatilization.
6. Analysis several problems may encounter
when conducting plant micropropagation.
Questions for Assignment
7. Evaluate the production of plant secondary
metabolite using cell and tissue culture
