OFAB and Modern Biotechnology in Ghana
OFAB AND MODERN BIOTECHNOLOGY IN GHANA BY DR. MARGARET OTTAH ATIKPO CSIR-FRI, ACCRA 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. Biotechnology in Ghana Biosafety Law passed in December, 2011 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). 4 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 GENOME SIZES OF DIFFERENT ORGANISMS Species Number of Chromoso mes Number of Genes Human 46 30,000 3,300 Mouse 40 30,000 2,500 Chicken 78 ~23,000 1,000 Fruit Fly 8 ~14,000 165 Corn 20 ~59,000 2,500 Rice 24 45-56,000 441 3,200 5 E. coli (Bact.) Size of Genome (million base pairs) 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. cls.casa.colostate.edu 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 GM-GROWING COUNTRIES Countries USA BRAZIL cotton Acreage Crops (million ha) 64.0 maize, soybean, cotton 21.4 maize, soybean, ARGENTINA 21.3 INDIA CHINA soybean, cotton 8.4 3.7 cotton cotton, tomato, papaya S.
