The experimental potatoes had been transformed with the Galanthus nivalis agglutinin (GNA) gene from the Galanthus (snowdrop) plant, allowing the GNA lectin protein to be synthesised. This lectin is toxic to some insects. Rats were fed raw and cooked genetically modified potatoes, using unmodified Desiree Red potatoes as controls.
The average potato has 0.075 mg solanine/g potato, which is equal to about 0.18 mg/kg based on average daily potato consumption. [ 19 ] Calculations have shown that 2 to 5 mg/kg of body weight is the likely toxic dose of glycoalkaloids like solanine in humans, with 3 to 6 mg/kg constituting the fatal dose. [ 20 ]
Several are potentially toxic, most notably the poisons commonly found in the plant species Solanum dulcamara (bittersweet nightshade) and other plants in the genus Solanum, including potato. A prototypical glycoalkaloid is solanine (composed of the sugar solanose and the alkaloid solanidine), which is found in the potato.
Solasodine is a poisonous alkaloid chemical compound that occurs in plants of the family Solanaceae such as potatoes and tomatoes. [1] Solasonine and solamargine are glycoalkaloid derivatives of solasodine. [1] Solasodine is teratogenic to hamster fetuses in a dose of 1200 to 1600 mg/kg. [2]

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.
