Discovery of genetic mechanism allowing potato cultivation in northern latitudes

(Phys.org) —An international team of scientists headed by Wageningen University, The Netherlands, has discovered a genetic mechanism which allows potato plants to develop tubers during the long days of spring and summer in northern latitudes. Wild potatoes, which originate in the Andes of South America, were brought to Europe by Spanish sailors in the late 16th century. Naturally occurring near the Equator, Andean potatoes develop tubers on days which are relatively shorter than those in high latitude summer.
