PLANT BIOTECHNOLOGY
 Dr.Ir. Andy Soegianto, CESA
What is Biotechnology ?
 Use of living organisms to solve problems
or make useful products
 Use of cells and biomolecules to solve
problems or make useful products
 Almost anything to do with biology &
technology
 Use of living organism or parts of them to
produce industrially goods or services

Progression of Biotechnology
The Era before Louis Pasteur


Alcoholic drinks (Beer, Wine, Palm-wine)
Fermented Food (Cheese, yoghurt, tape,
tempe, petis, terasi)
Progression of Biotechnology
The Era of Louis Pasteur
 Alcohol (Ethanol, Butanol, aceton, glycerol)
 Organic acids (Citric acid, acetic acid)
 Aerobic waste treatment
Progression of Biotechnology
The Era of Antibiotics
 Antibiotics (Penicillin, tetracyclin, streptomycin)
 Vaccine (NCD, polio)
 Steroid Transformation (DOPA)
 Liquid Medium Fermentation Technology
 Animal Tissue Culture Technology
Progression of Biotechnology

organism
 1975, monoclonal antibody (Hybridome
Technology
 Technology of diagnostic test using antibody

The Most Used Terms in Modern
Biotechnology
Transgene – Strange gene which is inserted
into a species
Example – Cry gene (gene codes for toxic protein
for Coleoptera)
Transgenic organism – an organism contains
of transgene by the process of
biotechnology (not a cross as in
plant breeding process)
Example – Bollgard cotton
Herbicide resistant maize
PRODUCTS OF MODERN
BIOTECHNOLOGY IN AGRICULTURE
GMO - Genetically modified organisms
An organism which has a new trait that is not found
before as a result of addition of gene derived from
another organism. Also called as Transgenic organism

 Gene controls toxin production is derived
from bacteria

The Differences between Plant
Biotechnology and Plant
Breeding
Plant Biotechnology
Plant Biotechnology allows the plant breeder a
wider choice of traits to choose from and allows
the trait to be realized in a more precise manner
and within a shorter time period.
Conventional plant breeding
• Can only use genes from within one species
or several closely related species or wild
species, becoming a limitation due to loss of
genetic diversity
• Takes many years to develop an improved
variety
Interspecific crossing in Plant
Breeding

process
Mutagenesis:
New trait, without a strange gene
 Mutagenesis changes DNA sequences of a gene
 allow to get a new advantageous trait

 “While traditional breeding approaches have
worked well, they can be very time consuming
and sometimes inefficient. Each plant has tens
of thousands of genes, so crossing two plants
results in a multitude of combinations.
 With advances in technology, scientists can now
precisely identify through marker technology
some of the individual genes responsible for
producing a particular characteristic. Traits such
as fruit color or resistance to a particular pest,
make breeding new varieties quicker and more
precise.
