Tomatoes, which today are considered the mainingredients of various salads and pizzas, were first eaten in South America. In the wild, they are very small, but modern varieties can be the size of a human fist. According to scientists, the first large tomatoes were grown by the Indians around the 15th century - most likely, they were obtained by crossing different species. This fact has been in the minds of scientists for a long time, and they were wondering if it was possible to somehow grow a tomato of unlimited size. As it turned out, this is entirely possible thanks to editing technology genes - If you slightly change at least one particle, you can grow tomatoes of gigantic sizes. At the same time, a huge tomato will retain the inherent benefits and nutrition inherent in ordinary fruits.
Genes - particles of DNA molecules in which it is storedinstructions for the development of animals and plants. Genes determine the presence of certain signs in them, therefore, by editing them, you can even change the size of the fruits of plants.
The benefits of tomatoes
On the subject of what exactly tomatoes are,You can argue for a long time. They can even be called fruits, but in Russia they are considered just like vegetables. The benefits of tomatoes are due to the high content of regenerating tissue and anti-stress vitamin C, as well as a high content of antioxidants. These substances slow down the oxidative processes in the human body and reduce the risk of cancer and cardiovascular disease.
Also, tomatoes are just very nutritious, thereforescientists believe that with the ability to grow their great fruits, humanity can be saved from starvation. A group of scientists from the USA, China and Japan took up the development of technology for growing huge vegetables. According to the scientific journal Nature Genetics, they really managed to find out exactly which factors restrain the infinite growth of tomatoes and how plants can be helped to go “beyond”.
In the course of scientific work, researchersthe researchers studied the genes for the bovine heart tomato variety. Like many other plants, the development of tomato fruits occurs on the tops of the stems. This is where the fabric is meristemwhose cells actively divide and ultimatelyas a result, they form juicy and appetizing fruits. Researchers have been following this process for a long time and find out which genes are responsible for the size of the fruit.
It turned out that two genes play an important role in this matter:
- WUSCHEL - stimulates growth;
- CLAVATA3 - tells the plant when it is necessary to stop this growth.
According to researchers, hundreds of years ago, a geneCLAVATA3, as it were, "learned" to stop the growth of tomatoes at a certain level. But today genes can be edited and, with a little intervention, you can give plants the opportunity to grow larger fruits. How exactly the editing of genes happens we have already told many times before - you can, for example, read the material of Vladimir Kuznetsov. But this is not the main thing, because now scientists have a real opportunity to save humanity from possible starvation.
This has not yet been proven, but with the help of a newtechnology, it will be possible to grow other gigantic vegetables. So, mankind has hope for getting kilogram cucumbers, potatoes and so on. How exactly the new technology will affect the taste of products is not yet clear, but intervention should not affect this property.

In general, due to a gradual increase in temperatureair on our planet, many plants run the risk of completely disappearing. For example, barley could be on the verge of extinction, leading to a shortage of beer. Researchers believe that barley can be grown only in some regions of our planet. Beer will become a rare drink, so its cost will be multiplied. I already wrote about this forecast of scientists in this material.
Also do not forget about another problemhumanity - environmental pollution by plastic trash. Recently, scientists from the United States and China found that microscopic particles can penetrate into plants and significantly slow down their growth. And this has already been proven in the course of a scientific experiment, which is described in detail in this material. Enjoy reading!
