Plant Genetic Systems

Plant Genetic Systems (PGS), since 2002 part of Bayer CropScience, is a biotech company located in Ghent, Belgium. The focus of its activities is the genetic engineering of plants. The company is best known for its work in the development of insect-resistant transgenic plants.

Its origin goes back to the work of Marc Van Montagu and Jeff Schell at the University of Ghent who were among the first to assemble a practical system for genetic engineering of plants. They developed a vector system for transferring foreign genes into the plant genome, by using the Ti plasmid of Agrobacterium tumefaciens. They also found a way to make plant cells resistant to the antibiotic kanamycin by transferring a bacterial neomycin phosphotransferase gene into the plant genome. PGS was the first company (in 1985) to develop genetically engineered (tobacco) plants with insect tolerance by expressing genes encoding for insecticidal proteins from Bacillus thuringiensis (Bt).

History

The company was founded in 1982 by Marc Van Montagu and Jeff Schell who worked at the University of Ghent, Belgium. In 1996 the company was acquired by AgrEvo. In 2000, Aventis CropScience was formed through a merger of AgrEvo and Rhône-Poulenc Agro. In 2002, Bayer CropScience is formed through Bayer's acquisition of the plant biotech branch Aventis CropScience.

gollark: The UK system does not work that way.
gollark: I have the "FX-991EX" because it's cheaper, which cannot graph but does at least have (bad) complex number support and whatever.
gollark: The Casio graphing ones are fairly user-modifiable and can play Tetris and stuff.
gollark: It's difficult to determine what a function looks like just by thinking hard about the derivatives and whatever.
gollark: Well, plotting functions is helpful.
