Before • Before genetically modified crops, people used selective breeding • This enabled people to create things such as: • Giant pumpkins • High yield wheat strains • Plants with high resistance to diseases
Now • Genetic engineering can be used to modify crops • Advantages • more advanced form of crop modification • Don’t have to go through the long process of selective breeding = very rapid to produce crops of desired type • No trail and error • Cross species can be done very easily
Facts about GMF • 1996 the first genetically modified food was commercially introduced • In 2006: • organic farming: 0.6% of worldwide production • GM farming : 2% • the rest being “conventional” • US produces 68% of the world’s genetically modified foods
Why genetically modified pumpkins? • To create the perfect jack-o'-lantern • deep orange colors • dark green stems that don't snap off • ideally shaped • Mostly sold around Halloween, sales were about $106 million in 2005 • 1.5 billion pounds of pumpkins were sold
Or to create unusual pumpkins • bumpy, heavily wart-covered pumpkins http://i.livescience.com/images/i/14520/i02/4-goose-bumps-02.jpg http://i.livescience.com/images/i/14505/i02/intro-mixed-pumpkins-02.jpg

Method • Plasmid vector containing gene is inserted into the biological system (here it is pumpkins) • Plasmid vector has 3 requirements • Must replicate itself • Must be useful to the host • Must be suitable to insert http://www.mun.ca/biology/desmid/brian/BIOL4900/1828B.JPG
