White, rice and maize are three examples of early experiments in agriculture. Below are the specific description about the history of Plant Genetic Engineering.
1859 - The first edition of The Origin of the Species had been published by Charles Darwin. This book had give the information on the knowledge of breeding at that time.
1865 - The breeding of peas that discovered by Gregor Mendel had been published. This breeding had became the foundation of modern genetics.
1913 - A genetic map had been constructed by A. H. Sturtevant.
1931 - Direct physical recombination had demonstrated by Barbara McClintock and Harriet Creighton. This physical recombination is actually about the linking of DNA from different chromosomes and maize chromosomes had been used in this demonstration.
1973 - Ti plasmid had been identified in a bacteria (Agrobacterium tumefaciens) that used in Plant Genetic Engineering. This Ti Plasmid are used as a vector to introduce foreign DNA into plant cells.
1983 - GM Plants had been created by four separate groups of scientists. Three groups had inserted bacterial genes into plants and another one group insert a bean gene into a sunflower plant.
1980's to early 1990's - China was a first country that had put GM crops on sale that is a virus-resistant tobacco and a tomato.
