1. "Genetisch Gewijzigde Organismen in relatie tot de voedselvoorziening in 't algemeen, en in 't bijzonder in ontwikkelingslanden” Discussie Forum 28 Januari 2010, Leuven Piet van der Meer Moderator

2. Introduction Historische context en introductie van de sprekers 11.00: Prof. Marc van Montagu 11.30: Dr. Vera Dua 12.00: Korte pauze 12.10: Algemene discussie 12.55: sluiting

3. Historical context • 10.000 years ago man changedfrom hunting animals and gathering plants in the wild, to keeping animals and growing plants – agriculture was born. • For thousands of years, man has selected and crossed animals and plants that had characteristics they liked, such as better taste or more yield. • In this process, humans have dramatically changed the animals and plants they originally found in nature.

6. Historical context For thousands of years, cross breeding was ‘trial and error’ 19th century: Gregor Mendel discovered the rules of inheritance. Early 20th century: discovery of hybrids Early 20th century: discovery of inducing mutations by radiation and chemicals.

7. Historical context While cross breeding and induced mutation are important tools of plant breeding, they also have limitations: Cross breeding only works between related plants. For some species cross breeding is extremely difficult. Cross breeding can take very long. Not only the desired genes are crossed over Mutation is undirected and unpredictable

8. Historical context Scientific developments in the 20th century to overcome these limitations: Discovery of ‘genes’ and of the building blocks - DNA. Discovery of genetic modification- identify a specific gene- isolate that gene, - transfer genes into plant cells

9. Traditional plant breeding x Related variety “elite” variety Genetic Modification  any gene source Genetic Modification of Plants

10. Genetic Modification of Plants Differences compared to conventional breeding: Specific Faster Possible with plants that do not cross sexually Much greater reservoir of genes

11. Genetic Modification Society has two questions for any new technology: Can it be useful? Is it safe?
