genetic engineering inventions

[86] In 1994 Calgene attained approval to commercially release the Flavr Savr tomato, a tomato engineered to have a longer shelf life. In 1983 a biotech company, Advanced Genetic Sciences (AGS) applied for U.S. government authorization to perform field tests with the ice-minus strain of P. syringae to protect crops from frost, but environmental groups and protestors delayed the field tests for four years with legal challenges. Independent development of agriculture occurred in northern and southern China, Africa's Sahel, New Guinea and several regions of the Americas. Can we change the blueprints of life? It was the result of a series of advancements in techniques that allowed the direct modification of the genome. [76] [41] In the late 1980s and early 1990s, guidance on assessing the safety of genetically engineered plants and food emerged from organizations including the FAO and WHO. [47], The ability to insert, alter or remove genes in model organisms allowed scientists to study the genetic elements of human diseases. The addition of foreign DNA in the form of recombinant DNA vectors generated by molecular cloning is the most common method of genetic engineering. [23] In 1907 a bacterium that caused plant tumors, Agrobacterium tumefaciens, was discovered and in the early 1970s the tumor inducing agent was found to be a DNA plasmid called the Ti plasmid. A pathway involved in the adaptive immune system, a relative newcomer in the world of pathogen defense, may have a more ancient role in protecting cells from invading viruses. [73], In 1976 Genentech, the first genetic engineering company was founded by Herbert Boyer and Robert Swanson and a year later the company produced a human protein (somatostatin) in E.coli. Cloning - One of the most controversial uses of genetic engineering has been cloning, or producing a genetically identical copy of an organism. As most people who read textbooks and things know, recombinant DNA technology started with pretty simple things--cloning very small pieces of DNA and growing them in bacteria--and has evolved to an enormous field where whole genomes can be cloned and moved from cell to cell, to cell using variations of techniques that all would come under genetic engineering as a very broad definition. Weill Cornell Medicine geneticist Christopher Mason speaks with, COVID-19 Research Biased Toward Only a Handful of Genes. [81] In 1987 Plant Genetic Systems, founded by Marc Van Montagu and Jeff Schell, was the first company to genetically engineer insect-resistant plants by incorporating genes that produced insecticidal proteins from Bacillus thuringiensis (Bt) into tobacco. The mice appeared normal, but after using radioactive probes he discovered that the virus had integrated itself into the mice genome. Understanding the history surrounding the progress of genetic engineering is incredibly important to understanding the current state of the field.
