اسلاید 1: Plant Biotechnology Plant TransgenesisWillie Parriman
اسلاید 2: What is Plant transgenesis?Plant transgenesis the transfer of genes to a plant directly. This enables us to create different kinds of plants that we arent able to produce with regular hybridization ways.
اسلاید 3: MethodsCloning Protoplast FusionLeaf Fragment TechniqueGene GunsChloroplast EngineeringAntisense Technology
اسلاید 4: CloningMany different types of plants can regenerate from a single cellPlant cloning is a way easier process then animal cloningThis is a natural ability for a plant so it makes them idealResearchers can see the genetic modification in a very short time after a new plant matures fast.
اسلاید 5: Protoplast FusionCallus-mass of cells will grow on an injured plantCell wall is dissolved with cellulase an enzyme leaving behind a protoplast which is fused to another species
اسلاید 6: Leaf Fragment TechniqueSmall disks are cut from a leafCultured in genetically modified AgrobacterAgrobacter-soil bacteriumGrowth hormones added which are nurse cells
اسلاید 7: Gene gunA force of Helium drives the particles to accelerationDNA coated particles are shot through the cell wallBiolistic Process-A cross between biology and ballistics
اسلاید 8: Chloroplast EngineeringDNA in the chloroplast accepts many new introduced genes at one timeNo chance that the genes will be blown off to other crops
اسلاید 9: Antisense TechnologyKeeps plants such as tomato plants ripe up to weeks Using Agrobacter researchers inactivated the process of decay and made it slow way down.
اسلاید 10: BenefitsVaccines for plantsStops virusGenetically modified PesticidesDefense against insectsSafe storage of foodavidin-a protein found in egg whites-from transgenic cornHerbicide resistant cropsResistant to glyphosate a common herbicideStronger fibersClassic breeding-1.5%Up to 60 % strongerEnhanced NutritonGolden rice-contains beta carotene-body converts to vitamin A
اسلاید 11: DisadvantagesHuman Health Environmental concernsPeople against genetically manipulating these plantsCould kill of insects or animals that eat the plants such as butterflies from corn“Super weeds”
اسلاید 12: conclusionDefinitionMethodsBenefits Disadvantages
اسلاید 13: QuestionsConcerning human health do you think we have to worry about the genetic manipulation of food?-ex. Soybean contained genes from the brazil nut that people have allergic reaction toEven though this technology can cut back on the use of chemicals on crops do you think it will cause problems for the environment?-ex. “super weeds” could breed from different crossing of genes
