GMO cottonseed meal and hulls are also used in food for animals. Potato: Some GMO potatoes were developed to resist insect pests and disease. In addition, some GMO potato varieties have been ...
Jan 6, 2022 · These problems can be addressed by genetic modification (GM) or gene editing (GE) and open a wide horizon for potato crop improvement. Current genetically modified and gene edited varieties include those with Colorado potato beetle and late blight resistance, reduction in acrylamide, and modified starch content.

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.

- Escherichia coli. In November 1973, geneticist Stanley Cohen and colleagues reported that they had built a plasmid, a ring of DNA, that carried a gene from another organism into an E. coli cell — the birth of genetic engineering (SN: 6/1/74).
- Transgenic mice. Mouse models are a go-to for scientists who want to study human disease in a controlled way in the lab. In 1974, biologists Rudolf Jaenisch and Beatrice Mintz laid the groundwork for these models by injecting DNA from simian virus into mouse embryos, which were later born with viral DNA in their genomes.
- Bt tobacco and more. In 1987, geneticist Mark Vaeck and colleagues reported that they had genetically engineered tobacco to produce Bt toxins. These toxins, made by the bacterium Bacillus thuringiensis, affect only certain insects, including several common agricultural pests.
- Flavr Savr tomato. The impact of the Flavr Savr tomato, introduced in 1994, is largely symbolic (SN: 5/28/94). Its genome was modified to block the production of an enzyme responsible for fruit softening, thus keeping the fruit firm longer.
Aug 10, 2015 · During the Irish potato famine, most potatoes were clones of their parents with nearly identical gene sequences. Had the population of cultivated potatoes been more genetically diverse (top panel), many potatoes would have had a greater opportunity to survive the deadly pathogen, P. infestans.
