GMO History: Evolution of Genetic Modification Over Time

Humans have been modifying plants and animals for thousands of years. This started about 12,000 years ago. People used selective breeding to choose the best animals and plants. They picked the ones with good traits for breeding.

They avoided breeding those without good traits. Selective breeding is the oldest method of changing genes. It is the beginning of what we now call genetic modification. Later, science gave people ways to change DNA directly.

In 1972, scientist Paul Berg created the first recombinant DNA molecule. He joined DNA from a monkey virus with DNA from a lambda virus. Herbert Boyer and Stanley Cohen made the first GMO in 1973. They took a gene that gave antibiotic resistance to bacteria. They placed it into a plasmid and inserted it into other bacteria.

The bacteria with the plasmid could survive the antibiotic kanamycin. In 1974, Boyer and Cohen inserted genes from a toad into bacteria. The toad was called Xenopus laevis. This became the first GMO to carry a gene from another kingdom.

First Genetically Modified Animals

1. Rudolf Jaenisch created the first genetically modified animal in 1974. He implanted a mouse embryo with foreign DNA.
2. This mouse became the first transgenic animal. At first, these mice could not pass the new gene to their offspring.
3. It took scientists eight more years to achieve this. In 1984, scientists made mice with cloned cancer-causing genes.
4. These mice were more likely to get cancer. In 1989, scientists created knockout mice. These mice had specific genes removed.
5. The first genetically modified livestock appeared in 1985. In 1987, mice were genetically modified to produce human proteins in their milk. These proteins helped treat blood clots.

First Genetically Modified Plants

1. In 1983, scientists created the first genetically modified plant.
2. They used tobacco for this experiment. Michael W. Bevan, Richard B. Flavell, and Mary-Dell Chilton led this work.
3. They used Agrobacterium to insert an antibiotic resistance gene.
   With tissue culture, they grew plants with this gene.
4. In 1987, scientists invented the gene gun. It helped modify plants that Agrobacterium could not infect. In 2000, Golden Rice was created. It was the first plant made to have extra vitamins. Golden Rice contains Vitamin A.

Synthetic Life and Modern GMOs

1. In 2010, the J. Craig Venter Institute made big news. They created the first synthetic bacterial genome. They named it Synthia. This was the first synthetic life. The first commercial GMO animal was the GloFish. It is a zebra fish with a gene that makes it glow.
2. GloFish was sold in the US in 2003. In 2015, the Aqu Advantage salmon became the first GMO animal approved for food. These salmon were raised in Panama and sold in the USA. They carried a Chinook salmon growth hormone gene. They also had an ocean pout gene. The GF salmon were able to grow all year round as a result.

Modern GMO Production Techniques and Processes

Creating a GMO is a step-by-step process. First, scientists select and isolate the gene they want. This gene can come from a living cell or be made in a lab. Sometimes, the gene is taken from a genetic library. The gene is then combined with other elements.

1. These include a promoter, a terminator, and a marker gene. These help the gene to function properly in its new host. There are different methods to insert the gene. In bacteria, scientists use heat shock or electroporation.
2. Microinjection or viral vectors are employed in animals. The methods found in plants are Agrobacterium, gene gun, or electroporation. Only a single cell acquires the new gene. That cell must develop into a whole organism.
3. Plants grow from tissue culture. Animals need the gene in embryonic stem cells. Scientists confirm the gene is present using tests. They use PCR, hybridization, and DNA sequencing. Earlier, gene insertion was random.
4. Now, precise methods like gene targeting are used. These processes take advantage of the cells’ natural DNA repair mechanisms. Genome editing makes these steps more accessible to researchers.
5. There are four main tools: Meganucleases, TALENs, ZFNs, and CRISPR. CRISPR and TALENs are the most popular today. TALENs are very specific. CRISPR is easy to use and highly efficient.

Global GMO Regulations and Safety Standards

Genetically modified organisms (GMOs) are controlled by strict government rules. These laws apply to research, farming, and food production. In 1975, the first safety guidelines were created. Later, the Cartagena Protocol became an international rule.

Countries like the USA and Europe follow different regulations. Europe requires clear labeling of GMO products. In the USA, GMO labeling became law in 2022. Some nations have banned GMOs, while others allow them under control.

Safety checks classify GMOs from Level 1 to Level 4. Despite strict laws, illegal GMO releases still happen. Many people prefer non-GMO labeled products for health and safety reasons.

Genetically Modified Bacteria (GMO Bacteria)

The first organisms modified by scientists in laboratories were bacteria. They are readily cultivated, easily stored, and modified. Genes can be transferred into bacteria, and they can be programmed to produce proteins, medicines, and enzymes.

For example, these proteins can help create insulin, help treat diseases like hemophilia, and produce important food products like cheese.

Some bacteria are utilized in agriculture to protect plants. Some are modified to be able to help eliminate or clean pollution. Scientists have even been looking at the modification of bacteria to treat diseases by changing bacteria in a person’s gut.

Genetically Modified Viruses

Viruses are used to carry genes into living cells. This helps treat some diseases by replacing damaged genes. Modified viruses are being tested to fight cancer, improve vaccines, and treat infections. Some viruses help control pests in farming. Scientists even use viruses to make batteries and new materials.

GMO Animals: Innovations in Genetic Engineering

Most genetically modified animals are still used for research. Very few are available in the market. In 2018, only three were approved in the USA. A goat and a chicken were made to produce medicines. A salmon was made to grow faster.

Changing animals is harder than changing plants. But the purpose is almost the same. These animals are made for research. They are also made to produce medicines and useful products. Some are made to help farming. Some are made to improve animal health.

Genetically Modified Fungi

Genetically modified fungi like yeast are used in making medicines, food products, and biofuels. They help produce complex proteins and chemicals. Some fungi are modified to kill pests such as mosquitoes that spread diseases like malaria.

CRISPR has been used to make mushrooms stay fresh longer by stopping browning.

GMO Plants: High‑Yield and Pest‑Resistant Crops

Plants are genetically modified to improve crop production, fight pests, and survive in poor conditions. Tobacco and Arabidopsis are commonly used in research.

Scientists also modify plants to change flower colors or make virus-resistant crops like papaya. Some plants may be altered for conservation or medical purposes.

Genetically Modified Fish: Advances in Aquaculture

Genetically modified (GM) fish are utilized in science, aquaculture, and kept as pets. GloFish and fast-growing salmon are examples of GM fish. GM fish can also be used to detect pollution, enhance food production, and aid medical research. Zebrafish are among the fish most commonly used to study human diseases.

Genetically Modified Insects Role in Farming and Health

Genetically engineered insects, primarily fruit flies (Drosophila), are used in genetic research because they contain a relatively simple genome and have a short reproductive cycle. Researchers also genetically modify mosquitoes to eliminate the diseases that they carry, such as malaria and dengue, through gene drives or sterilization methods that will eliminate large populations.

GMO Mammals Breakthroughs in Research

• Genetically changing mammals is slow and costly. It also takes a lot of effort. New tools like CRISPR have made this easier and faster. Earlier, scientists used viruses to insert genes into embryos.
• These embryos were placed in female animals. Then, they waited for the babies to grow. After birth, the babies were tested for the new gene.
• Mammals are good for studying human diseases. They help scientists to find cures. Mice are the most common choice. They are cheap and easy to handle.
• Pigs are also used. They are closer to humans in body size and functions. Monkeys are very close to humans. But using them is not widely accepted.
• In 2009, scientists changed the genes of marmosets for the first time. They were studying diseases like Parkinson’s.
• Mammals make human proteins better than plants or bacteria. These proteins are used as medicines. For example, in 2009, a goat-derived drug was approved to prevent blood clots. It was derived from goat’s milk. These protein from goats was subsequently found to treat a human with a disease called alpha-1-antitrypsin deficiency.
• Scientists are also using pigs for organ transplants. Modified pigs cannot spread viruses to humans. Their organs are less likely to be rejected. In 2023, a human got a pig’s heart. In 2024, a human received a pig’s kidney.
• Scientists also use green glowing genes in animals. This helps in research. Pigs and mice have been made to glow. This helps in organ studies. Glowing cats have been made too. They help study HIV. Cat HIV is like human HIV.
