  1. Genetically Modified Plants By: Amy Chen, Bridget Panych

  2. Genetically Modified Plants Summary • Makes changes to the hereditary material of a living organism • Biotechnologies are used to develop plants resistant to pests, diseases, drought, heat, or cold, and improve the nutritional content of plant food

  3. In 2006, a total of 252 million acres of transgenic crops were planted in 22 countries by 10.3 million farmers • Herbicide- and insect-resistant soybeans, corn, and cotton • Sweet potato resistant to a virus that could decimate most of the African harvest • Rice with increased iron and vitamins that may alleviate chronic malnutrition in Asian countries • Variety of plants able to survive weather extremes

  4. Examples of GM Plants • Roundup, made by Monsanto (agriculture company)- a herbicide that kills any plant that it touches • Created “Roundup Ready” crops • Crop ignores Roundup, but weeds are killed • Roundup Ready seeds reduce production costs and increase yield, so food becomes less expensive • Scientists have inserted genes that produce a natural insecticide into corn plants

  5. Genetically Modified Flower • Blue Roses • A Japanese company, Suntory • Delphinidin (produces blue pigment) • Growing the rose experimentally in Australia and the United States to get approval for sales

  6. Technology • Restriction enzymes • Ligase enzymes • Gene vector • Donor gene

  7. Diagram of Process

  8. Benefits • Crops • Preventing malnutrition/disease • Eliminating Pesticides • Environment • "Friendly" herbicides and insecticides • Conservation of soil, water, and energy • Better natural waste management • Society • Increased food security for growing populations

  9. Risks and Controversies • Safety • Human health impact: allergens, transfer of antibiotic resistance markers, unknown effects • Ethics • Violation of nature’s organisms • Tampering with nature by mixing genes among species • Objections to consuming animal genes in plants
