• The inserted sequence is known as the transgene. F1 plants Backcross 2 seed 87.5 elite BC1 plants Elite BC 2 plants are beginning to look more like the elite inbred parent. Spore preparation of this bacterium is used as a biological insecticide during the last 20 years.
In this article we will discuss about Transgenic Plants:- 1. Successful transformation by microinjection of cells has been achieved in tobacco , alfalfa etc.PowerPoint Presentation: Applications Insect resistant cotton – Bt toxin kills the cotton boll worm transgene = Bt gene from Bacillus thuringiensis Insect resistant corn – Bt toxin kills the European corn borer. 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.
Integration of the Transgene in the Genome of the […] The transgenic plants were resistant to the Manducta sexta, a pest of tobacco.
However, Agrobacterium cannot infect all plants since it has a narrow range of host specificity. Rice endosperm synthesize geranyl-geranyl pyrophosphate which can be converted into ß-carotene by 3 enzymes. contact the author of the presentation.
Transgenic plants – Herbicide resistance in transgenic plants. polygalacturonasesAntisense molecules: Antisense moleculesThe Golden Rice Fact : The Golden Rice Fact Rice, the principal crop of India is extremely low in vitamin A. 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. The exogenous DNA of interest is taken in microinjector and then directly delivered inside the cell. Under field conditions, application of herbicides not only kills the unwanted weeds but also greatly affects the field crops. Production of genetically modified plants with improved resistance to viral disease is one of the […] Phytoene desaturase and Lycopene ß Cyclase derived from daffodil( Narcisssus pseudonarcissus ) and Carotene desaturase from Erwinia uredova . Transgenic plants 1. 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.
Fundamentals of Transgenic Plant Development 4. Till date number transgenic plant varieties have been developed Transgenic plants ppt 1. 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. The protoplasts are immobilised in agarose or on glass slides coated with polylysine or by holding them under suction by a micropipette. Mercury, selenium and organic pollutants, like as polychlorinated biphenyls (PCBs), have been removed from soils by transgenic plants, containing genes for bacterial enzymes.
Transgenic Nicotiana tabacum cultivar Samsun plants. The transgenes providing these enzyme activities were transferred into rice Agrobacterium mediated transformation. Copy, By: Prгіxima slideshare.
