Ancient hybrid between tomato and a tuberless relative created the potato’s distinctive tuber

Genomic analysis published in Cell (2025) shows the potato lineage arose from an ancient hybrid between a tomato-lineage ancestor and an Etuberosum ancestor about 8–9 million years ago in southern South America, with two key genes (SP6A and IT1) from each parent driving tuber formation; domesticated ~7,000 years ago near Lake Titicaca, the potato is an evolutionary novelty that could inform modern breeding using wild relatives.

Uncovering the 9-Million-Year-Old Tomato Connection to Potato Origins

Scientists discovered that potatoes originated from a hybridization event between ancestors of tomatoes and Etuberosum around 9 million years ago, which allowed them to adapt to high-altitude habitats in the Andes and eventually led to domesticated varieties. This hybridization provided potatoes with unique traits like tuber formation, and understanding this process could help develop disease-resistant and climate-resilient potato crops through genetic engineering.
