10,000 - 9,000 BC
People start planting crops rather than relying on hunting and gathering for food.
6,000 BC
In Mesopotamia, Sumerians use yeast - a type of fungus - to make beer and wine.
5,000 BC
Farming communities in existence.
4,000 BC
Egyptians use yeast to make bread rise.
4,000 BC - 1,600 AD
Early farmers - like those in Egypt and the Americas - saved seeds from plants that produced the best crops and planted them the next year to grow even better crops.
3,000 - 2,000 BC
Peruvians select potatoes (from around 160 wild species) with the lowest levels of poisons and grow them for food.
1700 - 1720
Thomas Fairchild, the forgotten father of the flower garden, creates Europe’s first hybrid plant.
1750 - 1850
European farmers increase cultivation of legumes (to fix nitrogen in the soil) and rotate crops to increase yield.
1866
Austrian monk Gregor Johann Mendel publishes important work on heredity that describes how plant characteristics are passed from generation to generation.
1870 - 1890
Plant researchers crossbreed cotton to develop hundreds of new varieties with superior traits.
1871 - Early 1900s
Researcher Luther Burbank developed the Russet Burbank Potato, and later went on to develop several new hybrid fruits, including plums, berries, prunbes and peaches.
1908
First U.S. hybrid corn produced through self-pollination.
1919
Word ‘biotechnology’ coined by Hungarian immigrant Karl Ereky.
1928
Impact of X-rays and radium on barley mutation described.
1933
Hybrid corn becomes available commercially in the United States, causing corn yields to triple over the past 50 years.
1941
Discovery that chemicals can cause mutations.
1944
Discovery that DNA is genetic molecule - in other words, it is the way genetic information is passed between generations.
1953
Watson and Crick describe the double helix structure of DNA, providing more insight into how DNA carries genetic information.
1950s/1960s
Understanding of the structure of genes, and how they work deepens.
1960s
Work on creating high yield varieties of major grains, especially wheat, corn, millet, and rice massively increase production of these crops in many countries - launching the Green Revolution. The creation of dwarf wheat increases yields by 70%.
1973
Cohen and Boyer successfully splice a gene from one organism and move it into another, launching the modern biotechnology era.
1978
Boyer’s lab created a synthetic version of the human insulin gene.
1982
The first transgenic plant is produced - a tobacco plant resistant to an antibiotic. The breakthrough paved the way for beneficial traits, such as insect resistance, to be transferred to a plant.
1985
Field trials for biotech plants that are resistant to insects, viruses and bacteria are held in the United States.
1990
Genetic modifications used to make chymosin, an enzyme used in making hard cheese.
Late 1980s/Early 1990s
China first to put GM crops on sale, namely VR tobacco and a tomato.
1994
Transgenic FlavrSavr® tomato is approved for sale in U.S. groceries. It was developed to have more flavor and to have a longer shelf-life than conventionally grown tomatoes.
1995-1996
GM soybeans and corn are approved for sale, and GM cotton is commercialized in the United States. GM crops become the most rapidly adopted technology in the history of agriculture.
1996
GM tomato paste approved in the UK, first GM herbicide tolerant soya beans and insect protected maize approved in the E.U. In total, farmers in six countries plant GM crops on 1.7 million hectares.
1999
German and Swiss scientists develop golden rice, fortified with betacarotene, which stimulates production of Vitamin A that can prevent some forms of blindness.
2000
The first entire plant genome is sequenced, Arabidopsis thaliana, which provides researchers with greater insight into the genes that control specific traits in many other agricultural plants.
2001
U.S. and Canadian scientists develop a transgenic tomato that thrives in salty conditions, a discovery with the potential to create tomatoes and other crops that can grow in marginal conditions.
2002
The National Center for Food and Agricultural Policy (NCFAP) study found that six GM crops planted in the United States - soybeans, corn, cotton, papaya, squash and canola- produced an additional 4 billion pounds of food and fiber on the same acreage, improved farm income by $1.5 billion and reduced pesticide use by 46 million pounds.
2003
Farmers in 18 countries plant GM crops on 67.7 million hectares.
2004
Farmers in 17 countries plant GM crops on 81.0 million hectares.
2005
Farmers in 21 countries plant GM crops on 90.0 million hectares.
