And are too Thousands of stories have begun with a hundred ways to produce potatoes, and thousands of stories have begun with a Vodka shot. For centuries, potatoes have been playing an important role in feeding the growing population of the world. According to a study, the introduction of potatoes from the United States was a quarter of the population increase in the old world between 1700 and 1900.
Now, science reveals the amazing origin of vegetables: it emerged 9 million years ago as a result of an extraordinary hybridization between tomato ancestors and an ancient South American plant. This revelation re -writes the evolutionary history of the most used foods in the world and also explains how a simple tabar became an important place in global food.
Researchers at the Chinese Academy of Agricultural Studies conducted the largest genomic analysis on pet potatoes to date. He studied the varieties cultivated with 44 wild species, conducting extraordinary genetic continuity. A steady mixture of genetic materials came out between the results Solanum Tabrosum (Traditional potatoes) and the ancestors of Solanum LikeProSicum (tomato)
The search shows that like potatoes, we know that today they were born from the process of hybridization between ancient tomato plants and others. SurnameFrom the species related to the Atobarosum Family, who did not prepare the Taber until then. The results have been published in the journal Cell.
Both potatoes and tomatoes share a shared ancestors that lived about 13 million years ago. Four million years later, their offspring successfully interferes. A new plant has emerged from this union that has the ability to make the cold: subway structures that store energy in the form of carbohydrates and allow waterproofing without the need for seeds or germination. This biological innovation helped expand the first potatoes in various climate areas, from hot environment to cold environment.
The study also identified the disclosure of genetic details. The SP6A gene, which is considered a “switch”, determines that the plant will produce a timber, comes from tomatoes. On the other hand, the IT1 gene, which regulates the development of the subway trunks, which is a edible family, comes from the South America -based Atobarosum Family plants.
Considering the history of hybridization and geographical researchers of the species included, researchers suggested a speculation about the beginning of potatoes. During the meusian, between 10 and 6 million years ago, the sudden geological development of Andes, driven by the collision of two tectonic plates, produces new cold climate regions. Scientists believe this geological change forced the plants to be alive to survive and expand, two of them joined together to form Solanum TabrosumWhich will end in the form of a French fries with your hamburger millions of years later.
