1 NDSU Extension What is Biotechnology? Phil McClean Department of Plant Science North Dakota State University Unit 4 Biotechnology Meeting Grand Forks, ND March 6, 2003

2 NDSU Extension What is Biotechnology? How about some definitions General Definition The application of technology to improve a biological organism Detailed Definition The application of the technology to modify the biological function of an organism by adding genes from another organisms

3 NDSU Extension An organism showing a novel trait not normally found in the species What is the Result of Biotechnology? Extended shelf-life tomato (FlavrSavr Tomato) Herbicide resistant soybean (Roundup Ready Soybean)

4 NDSU Extension Biotechnology Terms You Probably Heard Transgene – the foreign gene added to a species Ex. – modified EPSP synthase gene (encodes a protein that functions even when plant treated with Roundup) Transgenic – an organism containing a transgene introduced by technological (not breeding) methods Ex. – Roundup Ready Crops

5 NDSU Extension Biotechnology Develops GMOs - Genetically modified organisms GMO - an organism that expresses traits that result from the introduction of foreign DNA Also called transgenic organism

6 NDSU Extension Important Terms Breeding Transformation Source: USDA Beneficial gene added from the same species Gene delivered by mating within the species Beneficial gene added from another species Gene delivered by plant genetic engineering

7 NDSU Extension Let’s Be Up Front Breeding  Biotechnology Breeding only exchanges genes found in the species Breeding can transfer the transgene to other breeding materials BUT it is not the same as biotechnology Biotechnology adds traits not available in the species Soybean does not have a gene to breakdown Roundup The gene comes from bacteria

8 NDSU Extension WheatRye Triticale X Interspecific Cross New species, but NOT biotechnology products

9 NDSU Extension ATTCGA ATTGGA Susceptible Normal Gene Resistant Mutant Gene Mutagenesis Treatment Mutagenesis: New Trait, No Foreign Gene Mutagenesis changes the sequence of a gene New, useful traits can be obtained

10 NDSU Extension BASF Clearfield Products Herbicide resistance imidazolinones Mutant AHAS enzyme developed by mutagenesis Crops Canola, Corn, Rice, Sunflower, Wheat In US Not considered GMOs by USDA regulators A Major marketing advantage When some stacked with GMOs, the advantage lost Mutagenesis Crops

31 NDSU Extension Biotechnology and Health ProductUse InsulinDiabetes InterferonCancer InterleukinCancer Human growth hormoneDwarfism Neuroactive proteinsPain

32 NDSU Extension What is Biopharming? Biopharming Definition Growing transgenic crops that express pharmaceutical products Examples: Drugs Antibodies Proteins

33 NDSU Extension Familiar Production Systems Why use this technology? Genes introduced into field crops (mostly corn) New productions systems not needed Producer can use traditional growing strategies Reduced End-Product Cost Animal system: $1000 - $5000 per gram protein Plant System: $1 - $10 per gram protein Source: The Roanoke Times, 2000

34 NDSU Extension Edible Vaccines – A Biopharming Dream Biotech Plants Serving Human Health Needs A pathogen protein gene is cloned Gene is inserted into the DNA of plant (potato, banana, tomato) Humans eat the plant The body produces antibodies against pathogen protein Human are “immunized” against the pathogen Examples: Diarrhea Hepatitis B Measles

35 NDSU Extension Tooth decay Future Health-related Biotech Products Vaccines Herpes hepatitis C AIDS malaria Streptococcus mutans, the mouth bacteria releases lactic acid that destroys enamel engineered Streptococcus mutans does not release lactic acid destroys the tooth decay strain

36 NDSU Extension Environmental Applications Bioremediation Indicator bacteria cleanup contaminated sites uses microbes designed to degrade the pollutant contamination is detected in the environment microbes sensitive to certain pollutants

37 NDSU Extension Recent Crop Biotechnology News The European Union Moratorium A five year EU biotech crop moratorium is in place Nov 2002: Labeling and traceability regulations drafted Jan 2003: Some countries looking to go GMO-free Feb 2003: Some EU countries want the moratorium to continue until regulations approved

38 NDSU Extension EU Labeling Regulations Foods with less than 0.9% of GM gene product Labeling not required Products derived from a GM crop Labeling required Applies even if the product does not contain the GM gene product Ex: Corn syrup: does not have the Bt protein, but must be labeled Animal feeds from GM crops Same guidelines apply

39 NDSU Extension EU Traceability Regulations GMO containing food must be declared at departure point List does not have to be modified if part of shipment is off-loaded in route A compromise regulation: Some wanted documentation from each step of the route

40 NDSU Extension United States frustrated Might sue under WTO policy that prevents policies that restrict trade USDA Secretary Veneman: The US patience was "growing very thin" and "very strong action was needed". (Feb 27, 2003) US Trade Representative Robert Zoellick : "We've tried to hold off" filing a WTO case, “but we're getting to the point where our patience is running thin." (Mar 3, 2003) US Response to the EU Regulations

41 NDSU Extension Different Countries Different Decisions Germany (3/3/03) Would accept biotech crops once regulations approved Major decision: long considered an opponent to biotech crops Taiwan (2/27/03) Will permit field trails in 2003 Tasmania (2/28/03) Extends biotech crop ban for five years Wants to remain a biotech free and maintain their niche market

42 NDSU Extension What Are the Public Concerns? Economics Are we changing the economics on the farm? Environmental Are we irreversibly modifying the environment? Globalization Is technology becoming centralized in too few hands? Social Will we develop a class of genetic outcasts? Religious Are we playing God?
