Recently, some scientists in Israel did amazing work with our tomatoes: they made them drought-resistant! This means that these tomatoes can save water, but without losing their flavor and quality!
Tel Aviv University led this wonderful project. They used a technique called CRISPR To change a The gene In tomatoes. This is called a gene 9 Omani RiyalIt controls the so-called stomata found on the leaves of plants. Stomata are like small doors in leaves that allow water to escape and carbon dioxide to enter, which is similar to the air that plants need to live and grow.
When there is a drought, plants close these doors so that they do not lose too much water. But the problem is that by doing this, they also stop receiving enough carbon dioxide, which serves as food for plants. This affects their ability to grow and produce delicious fruit. That's where gene editing comes in: Scientists modified the ROP9 gene so that tomato plants can only close those little doors when it's very hot, but not during the day or evening.
What's even more amazing is that they tested these tomatoes in a large experiment with hundreds of plants. And imagine what? The genetically modified tomatoes used less water, but did not lose their yield, flavor, or quality! It's as if they found the perfect balance to make tomatoes stronger against drought without sacrificing what we love about them.
But this isn't just exciting news for tomato lovers. Scientists discovered something else during this experiment. Instead of focusing solely on how these doors (stomata) close and open, they found a new trick to the process. It turns out that there is a mysterious substance called… Reactive oxygen species Which also plays an important role. This result is not only fascinating for scientists, but it also helps us better understand how plants work.
This discovery makes sense in a world where the climate is becoming increasingly variable and water is becoming scarce. People are demanding more foodBut we don't want to cause more damage to the environment. These drought-resistant tomatoes promise to revolutionize the world of agriculture future Subordinate agriculture. They can handle conditions better difficultwhich means more food for all of us, and that's a excellent News!
However, it is also necessary to be careful. When we talk about gene editing, we must take into account the ethical and environmental implications. But so far, this achievement appears to be a big step forward in ensuring that we have enough food in the future without depleting our current natural resources.
Therefore, this scientific breakthrough not only gives us more resistant tomatoes, but also teaches us an important lesson: it teaches us that science can be our ally in the search for sustainable solutions to the challenges we face, not just with tomatoes, but with anything else. Food that we can obtain and genetically modify it.
