Flash polygalacturonasesAntisense molecules: Antisense moleculesThe Golden Rice Fact : The Golden Rice Fact Rice, the principal crop of India is extremely low in vitamin A. Thus, herbicide-tolerant crop plants have now been developed by genetically manipulating plant genomes resistant to specific herbicides. It mainly infect the wound site and causes disease symptoms.PowerPoint Presentation: Ti plasmid:- Ori T-DNA regions Vir region A region enabling conjugative transfer genes for catabolism of opinesGene gun method: Gene gun method The method was first used by Klein et al. Reasons for making Transgenic Crop Plants 3. The process is increasingly used to introduce new genes into a range of bacterial, fungal plant and mammalian species. You do not have the permission to view this presentation. Transgenic plants have also been used for bioremediation of contaminated soils. Transgenic plants, in many locations, offer a readily available, cheap and abundant source of food, which gives them an economic advantage. Insecticidal activity depends on a toxic protein called delta endotoxins. Transgenic plants have also been developed and are suitable for food industries (delaying ripening in tomato). Phytoene desaturase and Lycopene ß Cyclase derived from daffodil( Narcisssus pseudonarcissus ) and Carotene desaturase from Erwinia uredova . Spore preparation of this bacterium is used as a biological insecticide during the last 20 years. A maximum of 40-50 protoplasts can be microinjected in one hour. Presently, more than 50 types of genetically engineered plant species, called transgenic plants have been successfully developed. These plants can also be modified to adapt to different climates and growing conditions, which makes them especially popular among farmers with medium- to large-size farms, as those plants make their crop supplies more predictable. Transgenic plants are those transformed varieties of plants which contain a foreign gene or gene of interest incorporated into the genome of its cells or tissue. This deficiency can lead to blindness,diarhae,malaria and tuberculosis. Transgenic plants : Transgenic plants Presented by Subhasmita Pattnaikcontents: contents Introduction Methods of producing transgenic plants Applications Strategies of Transgenic plants Transgenic plants in India Benefits ConclusionIntroduction: Introduction Transgenic plants are the results of modern biotechnology. Initially transgenic plants were developed more in dicotyledons, but now extended to several monocotyledons like wheat, maize, rice and oats. The transgenic plants were resistant to the Manducta sexta, a pest of tobacco. All rights reserved. In genetically engineered plant cells, a bacterium Agrobacterium is mainly involved in transfer of foreign gene. Transgenic plants have genes inserted into them, deriving from other species. Under field conditions, application of herbicides not only kills the unwanted weeds but also greatly affects the field crops. Integration of the Transgene in the Genome of the […] 3. Transgenic plants are those transformed varieties of plants which contain a foreign gene or gene of interest incorporated into the genome of its cells or tissue. Transgenic plants with this gene have been developed, demonstrating effectiveness of this gene for protection against herbicide ‘Basta’.

A.tumefaciens is a rod shaped Gram negative soil bacterium found in the rhizosphere . ramanand.patil007 Electroporation is a process of creating temporary pores in the cell membrane by application of electric field. Till date number transgenic plant varieties have been developed Prгіxima slideshare. In this article we will discuss about Transgenic Plants:- 1. Plants have been engineered to produce human proteins, such as hormones, in their seeds. Copy, By: Numeric tags are not allowed. on Transgenic plants – Herbicide resistance in transgenic plants. WHAT ARE TRANSGENIC PLANTS? into cytoplasm. It will have a transgene in every cell 2 A Hemizygous plant has only one copy of a transgene. Your email address will not be published. (89 month(s) ago). transgene = Bt proteinPowerPoint Presentation: Herbicide resistant crops - soybean , corn, canola transgene = EPSP synthase Virus resistance papaya - resistant to papaya ring spot virus transgene = virus coat proteinProlonged storage time: Prolonged storage time Transgenic tomato with delayed ripping:lower level of ethylene production Reduced activity of the cell wall degrading enzymes, e.g. Reduction of sicknesses and illnesses, as transgenic crops are more nutritious. BC2 plants 28 Transgenic line Elite The backcross progeny are becoming genetically similar to the elite parent. Title: A transgenic plant can be 1 A transgenic plant can be grown from a transformed tissue culture cell. Sugars, fatty acids, starch, cellulose, rubber and wax are obtained from plants; transgenic are made to get more production. HTTPS (Hypertext Transfer Protocol Secure) is a protocol used by Web servers to transfer and display Web content securely. (1987) to transform epidermal cell of Allium cepa . We can begin to grow foods in different conditions. Transgenes are the genetically engineered gene added to a species. Through genetic modification, the oil-producing soya bean was tailored to produce a wide range of industrial lubricants, cosmetic compounds and detergents that are biodegradable. Under normal circumstances, herbicides affect photosynthesis or biosynthesis of essential amino acids. Vitamins and minerals can be provided to children and to people, where they were inaccessible before. Enter one or more tags separated India now occupies second position in terms of global cotton production by turning out 35 million bales of cotton in 2010.Benefits: Benefits More economically friendly as pesticides do not go into the air, soil, and water .Their production hazards to the environment also decreases. Plant viruses are the potential candidate in affecting crop yield. These plants were made to resist insect pests, viruses or herbicides through incorporation of foreign gene into DNA of host plant cells. Micromanipulator is used for microinjection of the DNA. The transgenes providing these enzyme activities were transferred into rice Agrobacterium mediated transformation. In these plants, one or more genes coding for desirable traits have been inserted. Transgenic Plant Combat To Viral Resistance, TRANSGENIC PLANTS WITH ABIOTIC STRESS RESISTANCE. Creation of such pores in a membrane allows introduction of foreign molecules such as DNA, RNA, antibodies, drugs, etc. However, Agrobacterium cannot infect all plants since it has a narrow range of host specificity. The first transgenic plant was produced in 1983, when a tobacco line expressing kanamycin resistance was produced. Therefore other techniques have been developed to introduce foreign DNA into plant cells. 6. Several conventional methods such as breeding for resistance, heat treatment are enforced to combat viral menace. Genes from Bacillus thuringiensis (Bt2) have been introduced into several crops, including tomato and cotton, and field-testing has demonstrated impressive results against many pests. To prevent users from facing this, Use HTTPS option. F1 plants Backcross 2 seed 87.5 elite BC1 plants Elite BC 2 plants are beginning to look more like the elite inbred parent. Customize Embed, Thumbnail: The mechanical particle delivery or gene gun methods to deliver DNA on microscopic particles into target tissue or cells. In the US, by 2009-10, 93% of the planted area of soybeans, 93% of cotton, 86% of corn and 95% of the sugar beet were genetically modified varieties.
