Plant BiotechnologyPlant Transgenesis Willie Parriman 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 aren't able to produce with regular hybridization ways. Methods Cloning Protoplast Fusion Leaf Fragment Technique Gene Guns Chloroplast Engineering Antisense Technology Cloning Many different types of plants can regenerate from a single cell Plant cloning is a way easier process then animal cloning This is a natural ability for a plant so it makes them ideal Researchers can see the genetic modification in a very short time after a new plant matures fast. Protoplast Fusion Callus-mass of cells will grow on an injured plant Cell wall is dissolved with cellulase an enzyme leaving behind a protoplast which is fused to another species Leaf Fragment Technique Small disks are cut from a leaf Cultured in genetically modified Agrobacter Agrobacter-soil bacterium Growth hormones added which are nurse cells Gene gun A force of Helium drives the particles to acceleration DNA coated particles are shot through the cell wall Biolistic Process-A cross between biology and ballistics Chloroplast Engineering DNA in the chloroplast accepts many new introduced genes at one time No chance that the genes will be blown off to other crops Antisense Technology Keeps plants such as tomato plants ripe up to weeks Using Agrobacter researchers inactivated the process of decay and made it slow way down.
