History

DNA Plant Technology was founded in 1981 by Dr. William R. Sharp and Dr. David A. Evans, in Cinnaminison, New Jersey, "to develop tastier, value-added plant-based products for industrial and consumer markets" using "advanced plant-breeding techniques, tissue-culture methods and molecular biology in developing premium food products and improving agricultural raw materials." [1] By 1986, the company had gone public (NASDAQ:DNAP), and had partnerships with American Home Foods, Campbell Soup, Firmenich (a fragrance and flavor company), General Foods, Koppers Company, Hershey Foods, Brown and Williamson Tobacco, United Fruit, and others. [1]

By 1992 the company was investing heavily in genetic engineering and had invented, and obtained an issued patent [2] for, the fish antifreeze gene that would become part of the infamous Fish tomato. [3]

In 1993, DNAP purchased the Freshworld premium fruit and vegetable brand from Du Pont for a mixture of shares, cash and intellectual rights valued at over $30 million. [4]

In 1994, their headquarters moved to Oakland, California. [5]

In 1996, the company was out of cash, and agreed to a merger with Empresas La Moderna, S.A. de C.V. (NYSE/ADR:ELM) (“ELM”) through ELM's subsidiary, Bionova, which also controlled the seed company, Seminis. [6] [7] [8] The company became a wholly owned subsidiary of DNAP Holding Corporation (NASDAQ: DNAPD) of which it retained a 30% equity stake. ELM and Bionova were controlled by Alfonso Romo Garza. ELM was a company based in Monterrey, Mexico that operated in three fields: cigarettes (where it held 53% of the Mexican market), vegetable seeds, and packaging. [7]

In 1999 DNAP Holding Corporation changed its name to Bionova Holding Corporation [9] and changed its NASDAQ ticker to BNVA. [10]

In 2002 Bionova closed down its R&D operations, which had been carried out through its DNA Plant Technology subsidiary. [11]

Major works

Fish tomato

In 1991, DNA Plant Technology applied for and were granted permission to conduct a field test permit for their transgenic fish tomato product (tomato; antifreeze gene; staphylococcal Protein A) from the USDA's Animal and Plant Health Inspection Service. [12] This product remains controversial [13] in the history of biotechnology, because an antifreeze gene isolated from an arctic flounder was transgenically inserted into a tomato in an attempt to create a frost-tolerant tomato. Although this product was tested in a greenhouse, and may have been tested in the field, it was never commercialized.

In 1995, DNA Plant Technology unveiled a second generation of a different transgenic tomato and served it at a meeting of its shareholders. [14] That same year, DNA Plant Technology sold its wholly owned subsidiary called to Frost Technology Corporation to Simplot. [15]

Tobacco

Via its collaboration with the cigarette company, Brown & Williamson, DNA Plant Technology developed a genetically engineered cultivar of tobacco with a higher nicotine content, based on a high-nicotine strain already owned by Brown & Williamson called Y-1. Brown & Williamson and DNA Plant Technology were indicted by the US government for exporting the seeds to Brazil in violation of the Tobacco Seed Export law. [16]

Popcorn

In the mid-1980s, DNAP attempted to use somaclonal variation with corn to produce buttery-tasting popcorn without the need to add butter. [17]

Discovery of gene silencing

While working for DNA Plant Technology, the scientists Richard A. Jorgensen and Carolyn Napoli made discoveries about post transcriptional gene silencing that went on to form the basis of a number of U.S. patents on gene regulation and crop manipulation. Key experiments in the control of plant transgene expression were performed by Jorgensen after he joined DNA Plant Technology corporation / Advanced Genetic Sciences, Inc., including the modification of flower color in ornamental plants. This research led to the discovery of gene silencing when an extra copy of a key gene yielded white rather than blue flowers. [18]

In the 1990s, the FDA targeted DNA Plant Technology, charging that it had illegally smuggled Y1 Tobacco seeds out of the United States. The U.S. Justice Department charged DNA Plant Technology with one misdemeanor count of conspiracy to violate the Tobacco Seed Export law, prohibiting the export of tobacco seeds without a permit (a law which was repealed in 1991). [5] [19] DNA Plant Technology pleaded guilty in 1998 and agreed to cooperate with further investigations of Brown & Williamson. However, the U.S. Supreme Court eventually ruled in March 2000 that the FDA did not have the authority to regulate tobacco as a drug. [20]

Genetically modified organism Organisms whose genetic material has been altered using genetic engineering methods

A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), from animals to plants and microorganisms. Genes have been transferred within the same species, across species, and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered, or knocked out.

Genetic engineering Direct manipulation of an organisms genome using biotechnology

Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or "knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome.

Genetically modified food Foods produced from organisms that have had changes introduced into their DNA

Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits when compared to previous methods, such as selective breeding and mutation breeding.

Brown & Williamson American tobacco company

Brown & Williamson Tobacco Corporation was a U.S. tobacco company and a subsidiary of multinational British American Tobacco that produced several popular cigarette brands. It became infamous as the focus of investigations for chemically enhancing the addictiveness of cigarettes. Its former vice-president of research and development, Jeffrey Wigand, was the whistleblower in an investigation conducted by CBS news program 60 Minutes, an event that was dramatized in the film The Insider (1999). Wigand claimed that B&W had introduced chemicals such as ammonia into cigarettes to increase nicotine delivery and increase addictiveness.

As with all utility patents in the United States, a biological patent provides the patent holder with the right to exclude others from making, using, selling, or importing the claimed invention or discovery in biology for a limited period of time - for patents filed after 1998, 20 years from the filing date.

Pharming, a portmanteau of "farming" and "pharmaceutical", refers to the use of genetic engineering to insert genes that code for useful pharmaceuticals into host animals or plants that would otherwise not express those genes, thus creating a genetically modified organism (GMO). Pharming is also known as molecular farming, molecular pharming or biopharming.

Genetically modified crops Plants used in agriculture

Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. Examples in food crops include resistance to certain pests, diseases, environmental conditions, reduction of spoilage, resistance to chemical treatments, or improving the nutrient profile of the crop. Examples in non-food crops include production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation.

Genetic use restriction technology Methods for controlling the use of GMOs

Genetic use restriction technology (GURT), also known as terminator technology or suicide seeds, is the name given to proposed methods for restricting the use of genetically modified crops by activating some genes only in response to certain stimuli, especially to cause second generation seeds to be infertile. The development and application of GURTs is primarily an attempt by private sector agricultural breeders to increase the extent of protection on their innovations. The technology was originally developed under a cooperative research and development agreement between the Agricultural Research Service of the United States Department of Agriculture and Delta and Pine Land company in the 1990s and is not yet commercially available.

Y1 is a strain of tobacco that was cross-bred by Brown & Williamson to obtain an unusually high nicotine content. It became controversial in the 1990s when the United States Food and Drug Administration (FDA) used it as evidence that tobacco companies were intentionally manipulating the nicotine content of cigarettes. Y1 has also been investigated by the Pan American Health Organization (PAHO).

Plant genetics Study of genes and heredity in plants

Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. Plant genetics is similar in many ways to animal genetics but differs in a few key areas.

The United States is the largest grower of commercial crops that have been genetically engineered in the world, but not without domestic and international opposition.

Genetically modified tomato

A genetically modified tomato, or transgenic tomato, is a tomato that has had its genes modified, using genetic engineering. The first trial genetically modified food was a tomato engineered to have a longer shelf life, which was on the market briefly beginning on May 21, 1994. The first direct consumption tomato was approved in Japan in 2021. Primary work is focused on developing tomatoes with new traits like increased resistance to pests or environmental stresses. Other projects aim to enrich tomatoes with substances that may offer health benefits or be more nutritious. As well as aiming to produce novel crops, scientists produce genetically modified tomatoes to understand the function of genes naturally present in tomatoes.

History of genetic engineering Aspect of history

Genetic engineering is the science of manipulating genetic material of an organism. The first artificial genetic modification accomplished using biotechnology was transgenesis, the process of transferring genes from one organism to another, first accomplished by Herbert Boyer and Stanley Cohen in 1973. It was the result of a series of advancements in techniques that allowed the direct modification of the genome. Important advances included the discovery of restriction enzymes and DNA ligases, the ability to design plasmids and technologies like polymerase chain reaction and sequencing. Transformation of the DNA into a host organism was accomplished with the invention of biolistics, Agrobacterium-mediated recombination and microinjection. The first genetically modified animal was a mouse created in 1974 by Rudolf Jaenisch. In 1976 the technology was commercialised, with the advent of genetically modified bacteria that produced somatostatin, followed by insulin in 1978. In 1983 an antibiotic resistant gene was inserted into tobacco, leading to the first genetically engineered plant. Advances followed that allowed scientists to manipulate and add genes to a variety of different organisms and induce a range of different effects. Plants were first commercialized with virus resistant tobacco released in China in 1992. The first genetically modified food was the Flavr Savr tomato marketed in 1994. By 2010, 29 countries had planted commercialized biotech crops. In 2000 a paper published in Science introduced golden rice, the first food developed with increased nutrient value.

Genetically modified potato Potato that has had its genes modified using genetic engineering

A genetically modified potato is a potato that has had its genes modified, using genetic engineering. Goals of modification include introducing pest resistance, tweaking the amounts of certain chemicals produced by the plant, and to prevent browning or bruising of the tubers. Varieties modified to produce large amounts of starches may be approved for industrial use only, not for food.

The phrase edible vaccines was first used by Charles Arntzen in 1990 and refers to any foods; typically plants, that produce vitamins, proteins or other nourishment that act as a vaccine against a certain disease. Once the plant, fruit, or plant derived product is ingested orally, it stimulates the immune system. Specifically, it stimulates both the mucosal and humoral immune systems. Edible vaccines are genetically modified crops that contain added “immunity” for specific diseases. Edible vaccines offer many benefits over traditional vaccines, due to their lower manufacturing cost and a lack of negative side effects. However, there are limitations as edible vaccines are still new and developing. Further research will need to be done before they are ready for widespread human consumption. Edible vaccines are currently being developed for measles, cholera, foot and mouth disease, Hepatitis B and Hepatitis C.
