WHAT IS BIOTECHNOLOGY ?
Use of scientific methods to produce genetically
modified food crops that are more pest, disease
and drought resistant and with short maturity
periods.

Leading Institutions: CSIR, UG-Legon,
KNUST, BNARI, CRIG
R & D: Plant pathology, molecular breeding,
conventional breeding, tissue culture
Awareness Creation: NBC, FARA, SABIMA,
MEST
WHAT IS BIOTECHNOLOGY (BIOTECH)?
• Definitions:
• Bios (Greek) meaning life
• Technology – (Greek - technología);
meaning study of an art, skill or craft
‒ “Any technological application that uses
biological systems, living organisms or
derivatives thereof, to make or modify
products or processes for specific uses”
(CBD).

BIOTECHNOLOGY
– A range of different molecular technologies such as gene
manipulation, gene transfer, DNA typing and cloning of
plants and animals (FAO)
•
General definition:
– A laboratory technique used by scientists to change the DNA
of living organisms.
OLD AND MODERN BIOTECHNOLOGY
Old technology has been around for many years
and applied in the following:
– Industry - Beer brewing, cheese making,
employing the use of bacteria and yeast as well as
biological substances like enzymes. (Louis Pasteur)
{pito and kenkey production in Ghana}
– Agriculture – crossing of plants/animals to
generate improved varieties. (Gregor Mendel)
– Medicine – vaccinations e.g. smallpox (Edward
Jenner).
APPLICATION OF MODERN
BIOTECH
•Medicine (Red Biotech) – Vaccines, Hormones
e.g. insulin for diabetes.
• Industry (White/Grey Biotech) – Cleaning up
of oil spills, conversion of organic waste.
• Agriculture (Green Biotech) – Improved
varieties; major crops - maize, soya bean,
cotton.
( The Problem Area? )
Conventional Practices to Control the Challenges
Weeds - Tillage, hand weeding, herbicides (prefar,
glyphosate, glufosinate)
Pests/Diseases – Pesticides (organophosphates)
Yield - Increase in acreage
- Selection of animals/plants with good trait for
multiplication
(Unknown combination of genes. RISK ?, Very long time to
achieve desired results, Products accepted without any risk
assessment.)
- Increase in planting material (tissue
culture)
CHALLENGES FACING
FARMERS
Weeds
Pest and Diseases
Spoilage due to over-ripening/ transportation or marketing
Poor quality soils/ access to fertilizer/ credit/good health
Inadequate irrigation
Absence of appropriate technology
Poor infrastructure
Lack of mechanization
these could be addressed using biotechnology
CHALLENGES
Weeds - Tillage, hand weeding, herbicides (prefar,
glyphosate, glufosinate)
Pests/Diseases – Pesticides (organophosphates)
Yield - Increase in acreage
- Selection of animals/plants with good trait for
multiplication
(Unknown combination of genes. RISK ?, Very long time to
achieve desired results, Products accepted without any risk
assessment.)
- Increase in planting material (tissue
culture)
Tissue culture
– Parts of an adult plant cut into little pieces
– Treated to kill any fungi or bacteria living on
them
– Pieces put into jelly-like substance (agar)
containing plant food
– Shoots grow from the plant pieces and moved
to new plant food where roots and leaves grow
– Planted in covered pots to get stronger and
transferred to soil after a few weeks.
Examples: pineapple, banana, plantain
The Use of Modern Biotechnology to Control the Challenges
Selection of useful genes for;
Drought and herbicide tolerance
Insect resistance (maize, cotton)
Improvement in nutritional quality (golden rice)
Delayed ripening (tomatoes, melons, papaya)
HOW ARE THESE ACHIEVED?
DNA
The genetic material and the code for life
• Basic Building Blocks – Deoxyribonucleotides
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T)
• Universal for all living organisms – bacteria, man, insects and plants
• Entire DNA content of an organism is its GENOME
• DNA divided into sequences known as genes
• One gene, one protein (Central Dogma)
The diversity in life is due to the differences in genomes

INFORMATION FLOW IN A CELL
STEPS IN GENETIC ENGINEERING
•
•
•
•
•
Isolation of the genes of interest
Insertion of the genes into a transfer vector
Transfer of the vector to the organism to be modified
Transformation of the cells of the organism
Selection of the genetically modified organism
(GMO) from those that have not been successfully
modified
Tools In Molecular Cloning
•Restriction enzymes – Molecular Scissors
•
Vectors
•
DNA Ligase
•
Detection of cloned gene in vector
•
Sequencing
•
PCR amplification
CLONING PROTOCOL
Mode of Digestion
Cloning Strategy
Conventional Breeding vs. Modern Biotech
Conventional Breeding
Modern Biotechnology
• Limited to exchanges between the
same or closely related species
• Direct transfer of one or just few genes,
between either closely or unrelated
organisms
• Unknown combination of genes from
several crosses generated
• Only the desired trait transferred
• Undesirable gene can be transferred
along with desirable genes
• Long time to achieve desired results
• Results achieved in a shorter time
compared to conventional breeding
Herbicides tolerance (Ht) Technology
Why is this important?
Weeds compete with crops for:
Water
Nutrients
Sunlight
Space
Also harbour insects and disease pests and contaminate
harvest
If left uncontrolled will reduce crop yield considerably
Herbicides Tolerance (Ht) Technology Cont’d
Weeds also harbour
• Insects and disease pests
• Clog irrigation and drainage systems
• Undermine crop quality- deposit weed seeds into crop
harvests
If left uncontrolled can reduce crop yields
considerably.
Advantages of Herbicide Tolerant Plants
•
•
•
•
•
Vital tool for fighting weeds
Reduced number of spray in a season
Reduced fuel use (decreased carbon emissions)
Environmentally friendly
Ability to use no till systems
Bt Insect Resistance Technology
•
•
cotton
Bt – Bacillus thuringiensis
produces toxins (proteins) which kill
bollworm and corn borers
Delayed Ripening Technology
Application in
• Tomatoes – US, Canada, Mexico
• Melons
• Papaya – South East Asia
• Improvement in quality of the food as
i. shelf-life is extended,
ii. Losses minimized for both the farmer and
consumer
Nutritional Quality Enhancement (Golden Rice)
•Vitamin A deficiency - cause of
blindness in children
•Micronutrient fortification of
common cereals by genetic
engineering
•Insertion of 3 foreign genes for
critical enzymes for ß-carotene
biosynthesis in rice plant.

BENEFITS OF GM CROPS
•Higher yield – weeds and pests controlled
•
Reduced farm costs as a result of decrease in hiring of
farm
hands, purchase and application of insecticides thus resulting in increased
profits.
•
Increased health benefits for farmers.
•
Production of crops with increased nutritional properties e.g. Vit.
A fortification.
•
Production of drought-resistant crops (Abiotic stress).
PERCEIVED RISKS/THREATS
•Potential of introducing allergens and other anti-nutrients into food.
•Transgenes may escape into wild relatives.
•Pests may evolve resistance to toxins produced by GM crops.
•Toxins may affect other non-target organisms thereby affecting the ecosystem.
•Development of ‘super weeds’ as plants become resistant to herbicides.
•Socio-economic/cultural/ethical factors –:
i) dependence on multi-national seed companies
ii) farmers with small holdings pushed out of business

WHY REGULATE GM CROPS?
•
•
•
•
Assures food/ environment safety.
Necessary for technology development.
Facilitates technology transfer.
Needed to address public perception and
concerns.
• A requirement of Cartagena Protocol.
THE CARTAGENA PROTOCOL
Adopted - 29th Jan. 2000; Entered into force - 11th Sep. 2003;
Acceded by Ghana – 30th May, 2003.
• Addresses the safe transfer, handling and use of living
modified organisms (LMOs) that may affect biodiversity,
human health and environment.
• Focuses on transboundary movements of LMOs.
• Allows sovereign states independence in accepting
agricultural products of LMOs.
• Decisions communicated through Biosafety Clearing House.
