But if GM papayas are being sold in mainland supermarkets, this has to be an exceedingly well kept secret. India itself took another step forward in the cultivation of these crops in October 2007: the Missouri-based global seed giant, Monsanto, donated technology to Tamil Nadu Agricultural University, Coimbatore, for developing a papaya resistant to the ringspot . It should give complete information; Quinn TA. Introduction of the original transgenic variety, known as SunUp, and a derivative known as the Rainbow papaya (which was a cross between SunUp and a locally popular non-transgenic papaya variety) began soon after. Combining genes from different organisms is known as recombinant DNA technology and the resulting organism is said to be 'Genetically modified (GM)', 'Genetically engineered' or 'Transgenic'. Bacteria and GM mice were the first GMOs generated in 1973 and 1974 respectively. The papaya crop is severely affected by papaya ringspot virus (PSRV) worldwide. This reflects what happened in Hawaii, and it led to a loss of papaya plants. Genetically modified organisms (GMOs) are made by forcing genes from one species, such as bacteria, viruses, animals, or humans, into the DNA . Virus Resistant Papaya. Most rennet used today is commercially produced by genetically modified microorganisms (most commonly with GM fungi). Rainbow' papaya is a new hybrid variety developed by the College of Tropical Agriculture and Human Resources of the University of Hawaii at Manoa. and the Caribbean (and not genetically engineered). papayas grown in Hawaii are genetically modified to resist the ringspot virus, which nearly destroyed the Hawaiian industry for this fruit a few years ago. Some of the crops altered in this way include bananas, corn and papayas. Shutterstock. To … Products such as oil, high fructose corn syrup, and sugar are created from these crops and added to processed foods. In 1995, the first variety of genetically engineered yellow squash; resistant to zucchini yellow mosaic virus and watermelon mottle virus 2, was developed by the Asgrow Seed Co. A genetic sequence from the virus was inserted into the papaya genome. As the UK's national academy of science, the Royal Society has drawn on scientific experts to answer a number of questions about scientific and technological issues relating to GM crops.
