Who created GMOs?

AExpert Answer

The first use of recombinant DNA technology, was created by Cohen and Boyer in 1972 with E.coli in 1972 and this article explains this advancement in biotechnology in greater detail. Here is an excerpt:

“Their experiments dramatically demonstrated the potential impact of DNA recombinant engineering on medicine and pharmacology, industry and agriculture.”


Recombinant insulin was the first commercial product derived from genetic engineering techniques created in 1976 by the Genetech Company. Virtually all diabetics today use this type of insulin because of its advantages to the animal-derived insulin used before this technology. 


In the early 1980s there were many simultaneous plant modification efforts initiated. Mary-Dell Chilton, known as “the mother of plant genetic modification,” led a team at Washington University in St. Louis, Missouri, and successfully used Agrobacterium to insert a gene into tobacco plants. Robert Fraley, now the Chief Technology Officer at Monsanto but back then a PhD scientist at Monsanto, shared a similar achievement, using Agrobacterium to transport new genes into petunias. A third team at Ghent University in Belgium, led by scientists Jeff Schell and Marc Van Montagu, also succeeded in this area with Agrobacterium. These efforts in scientific research and development resulted in the world’s first genetically engineered plants.


Then there is the more familiar FlavrSavr tomato, created by Calgene and approved as the first GMO whole food in 1994. The tomato fruit enzyme polygalacturonase (PG) dissolves cell-wall pectin which is key to fruit ripening. The idea was to suppress PG accumulation in ripening tomatoes by introducing a reverse-orientation copy of the gene, an “antisense” copy designed to extend shelf life and storage. While demand for the tomato was high and remained high, profitability was limited. This tomato is no longer on the market.


The first genetically engineered product for human consumption, chymosin, was approved by FDA in 1999, which is added to milk during cheese making. This is also the preferred method as of today and prior to biotech solutions, these enzymes were extracted from the stomachs of calves. Biotech has enabled production that help cheese-makers to deliver the flavors and consistency that they — and we — are looking for, and eliminated the need to harvest this from calves.

While there might be some institutions with the capability to make these transgenic watermelon and coconut plants for you, that does not mean that you would be able to actually plant them out. First, the institution would need to have a Biological Use Authorization to work with recombinant DNA to make the vectors to transfer the genes. Then they would need to be able to do the tissue culture required to transfer the genes and regenerate whole plants again, which can sometimes be difficult.... Read More

I’m a genetic engineer. I’ve spent 30 years participating as a member of teams of genetic engineers, and I love your question. Most of us do indeed spend a lot of time inside the lab, but we’re not always sitting. Sometimes we dance!   Genetic engineering starts with an idea for a way to solve a problem, so I guess it starts with an understanding of the problems. In agriculture, for example, that means spending time to understand what’s happening on farms and... Read More

Other than research, our work starts at the design of a plasmid vector that contains a gene cassette that we want to introduce in a plant genome. Once the plasmid vector design is completed, it is synthesized by bringing together several DNA components together thru a bio-chemical reaction. When the plasmid vector is made, the several components are verified by restriction endonuclease digestion reactions and/or thru DNA sequencing. After this verification is completed, the plasmid...
