Potato traces its ancient roots to tomato hybridization
Tokyo, Japan (SPX) Aug 01, 2025 An international team of scientists has traced the evolutionary origin of the modern potato to a natural hybridization event between wild tomato relatives and Etuberosum species in South America roughly 9 million years ago. Published in Cell, the study reveals that this interbreeding introduced critical genetic material enabling the formation of tubers-specialized underground structures fo
How ancient tomato genes created the potatoes we eat today
Potatoes might be one of your favorite foods, whether baked, fried, or mashed. But have you ever wondered where they came from? Scientists have finally uncovered a surprising family secret about potatoes, and it involves an unlikely relative: tomatoes. About nine million years ago, in the wild regions of South America, a tomato plant and a potato-like species called Etuberosum interbred. This unusual partnership led directly to the potatoes grow…
A study showing the origin of potatoes, one of the world's most important agricultural crops, has confused scientists. But a team of multinational researchers has been able to discover the secret by analysing 450 genomes of cultivated potatoes and 56 species of wild potatoes. The main preparer of the study, Chiang Chang of the Institute of Agricalcher Genumix Insteet, in Chinese Shenzhen, has shown that "it is very difficult to collect samples o…
