electroporation transformation slideshare

Methods of plant transformation See our User Agreement and Privacy Policy. Transformation: • Transformation is the process by which genetic makeup of an organism is altered by the insertion of new gene(or exogenous DNA) into its genome .This is usually done using vectors such as plasmids. Particle gun Method; a gene gun method was originally designed for plant transformationThis video is about: Particle gun Method . In order to be transformed, E. coli cells must first be made competent, which means capable of taking in DNA molecules from their environment. Bacterial cell wall is made up of peptidoglycan and its derivatives. The exogenous DNA is incorporated into the host cell’s chromosome via recombination. Give the three basic transformations 3. Some other bacteria, on the other hand require the incorporation by artificial methods such as Ca ++ ion treatment, electroporation, etc. More recently, techniques for electroporation have 1984), electroporation (e.g. Moreover, transformation frequency can be improved by using linear DNA instead of circular one, by giving heat sock to protoplast at 45°C for 5 minutes, by adding PEG and using 1.25 kV/cm voltage. The transformation efficiency is around 10 9 transformants per microgram of DNA for small plasmids (about 3kb) and about 10 6 for large plasmids (about 130 kb). • A method used to apply an electric current across a cell membrane resulting in temporary “pore” formation enabling the uptake of ex… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Transfection: it’s a process of introducing nucleic acid into live eukaryotic cells. 6. Microinjection . 1. Transformation using electroporation was developed in the late 1980s, increasing the efficiency of in-vitro transformation and increasing the number of bacterial strains that could be transformed. In: Plant Genetic Transformation and Gene Expression. See our Privacy Policy and User Agreement for details. Today the gene gun is used for genetic transformation of many organisms to introduce a diverse range of desirable traits. doi:10.111 1/j.1574-6968.1989.tb03039.x Gelvin B. S. (2003) Agrobacterium-Mediated Plant Transformation: the Biology behind the “Gene-Jockeying” Tool. Electroporation transformation. The transformation was the first time applied by British Bacteriologist Frederick Griffith in 1928 in diplococcus pneumonia. Electroporation has been used successfully for transient (when foreign gene which is present in cell but not integrated in the chromosome, shows expression in cytoplasm) and stable transformation (foreign gene integration in host chromosome and is expressed) of protoplasts from a wide range of species. 1. Microinjection is technically easy because of large size of oocytes. The overall advantages of using Agrobacterium-mediated transformation over other transformation methods are: reduction in transgene copy number, and intact and stable integration of the transgene (newly introduced gene) into the plant genome (Jones et al., 2005).. Further Reading. Theory. the generation of transgenic organisms. exogenous molecules found in the medium to Clipping is a handy way to collect important slides you want to go back to later. Bacterial species that have been transformed by electroporation (1990) Bio-Rad Laboratories, 1414 Harbor Way South, Richmond, CA 94804 Bull. • Efficiency: A large majority of cells take in the target DNA or molecule. Chicken tracks in the dirt are an example of which transformation? Several methods of transformation in yeast cells (Figure 1) have been developed. In electroporation, electric charges are stored in a capacitor to build a high voltage, the sample is struck by the impulse voltage, and the exogenous nucleic acid can be transferred instantly into cells. In the past, traditional plant breeders practice classical breeding techniques to propagate plants with desirable traits. Transfection vs. Transformation is defined as the process in which the genetic material of an organism is altered by the integration of new genes into its genome. turn. Plant transformation: Integration of the DNA into a plant genome (nuclear or cytoplasmic). (1991). Irreversible electroporation is a soft tissue ablation technique using ultra short but strong electrical fields to create permanent and hence lethal nanopores in the cell membrane, to disrupt cellular homeostasis. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. “pore” formation enabling the uptake of In the past, traditional plant breeders practice classical breeding techniques to propagate plants with desirable traits. (This transformation has two steps) 5. A Laboratory Manual. The electroporation procedures Electroporation 4. 1985), and fusion of protoplasts with liposomes (Deshayes et al. The Particle bombardment device, also known as the gene gun, was developed to enable penetration of the cell wall so that genetic material containing a gene of interest can be transferred into the cell. Pasz‐kowski et al. Which transformation do the following stand for? Transfer 50 μl of electrocompetent cells to a pre-chilled electroporation cuvette with 1 mm gap. 1. Advantages vs. Now customize the name of a clipboard to store your clips. across a cell membrane resulting in temporary Another artificial method of transformation is electroporation, in which cells are shocked with an electric current, to create holes in the bacterial membrane. Liposome Encapsulation (Lipofection) 5. flip. See our User Agreement and Privacy Policy. • A method used to apply an electric current You can change your ad preferences anytime. Applications: Natural transformation in gramNatural transformation in gram negative bacterianegative bacteria 14. Transformation methods 2. Looks like you’ve clipped this slide to already. Electroporation has been used successfully for transient (when foreign gene which is present in cell but not integrated in the chromosome, shows expression in cytoplasm) and stable transformation (foreign gene integration in host chromosome and is expressed) of protoplasts from a wide range of species. Transgenic plants for insect resistance (review), mechanism of resistance in plant against insects, No public clipboards found for this slide, Overview of Electroporation and Applications. 1631. Plant transformation is now a core research tool in plant biology and a practical tool for transgenic plant development. The apoptosis rate using the electroporation method is very high.
