A transgenic organism is one whose genome has been subject to artificial
modification. A transgenic organism may result when foreign DNA is inserted into
the nucleus of a fertilized embryo. Bacterial transformation is another example of a process that leads to a transgenic organism.

GMO - Genetically modified organism (GMO) is Genetic material of an organism is  altered with the help of genetic engineering techniques generally known as recombinant DNA technology. DNA molecules from one source is combined with the DNA of other in vitro into one molecule to create a new gene. The recombinant DNA is then transferred into an organism causing the expression of modified or novel traits. The product is also known as an Genetically Engineered Organism or GEO.

Examples Transgenic animals (mice, fish),  transgenic plants (BT Cotton, Flavour Savour Tomato), or various microbes (fungi and bacteria) . The production and use of GMOs are ivolved in biology or medicine, for the production of pharmaceuticals and industrial enzymes, and for direct, and often controversial, applications aimed at improving human health (e.g., gene therapy) or agriculture (e.g., golden rice). For example, a gene from a jellyfish, encoding a fluorescent protein called GFP, can be physically linked and thus co-expressed with mammalian genes to identify the location of the protein encoded by the GFP-tagged gene in the mammalian cell. The indispensable use of GMO is in many areas of research, such as to study the mechanisms of human and other diseases .

Transgenic crops with TPS will not spread their genes to surrounding plants.
The TPS genes are transferred on pollen, so any plant pollinated by a TPS plant will produce dead seeds.
This would prevent accidental gene flow from transgenic crops to wild plant populations.
Companies may develop improved crop varieties .If a seed company knows it will be able to "protect its
investment" in the development of new varieties, including transgenics, by preventing farmers from saving seed and replanting from year to year, more effort will be put into the development of improved varieties.

Transgenic plants have been used to produce insect resistance plants like cotton, soya and corn. But now efforts are ben made to produce plants with improved product quality. In addition to that transgenic plants are going to be most sought after bioreators for producing edible vaccine, anitbodies, bioplastic, highly saturated oil, pharmaceuticals, and for many other metabolic products and byproducts of ecomonic importance.
