A breakthrough in RNA by 50% increases the yield of potatoes and rice16 октября, 2021
Dozens of years scientists are looking for ways to increase the productivity of crops, hoping to find a solution to the problem of food deficiency in the conditions of an unfavorable climate and population growth. However, most of the existing methods are complex and require high time costs. The international team of researchers has discovered a new approach. It allows not only to significantly increase the yield of cultures, but also strengthen drought resistance.
From the school courtyard of biology, we know that RNA molecules receive instructions from DNA and produce proteins that perform various tasks. But in 2011, the Laboratory of Professor Huel Chuan from Chicago University has opened a new way of expression of genes in mammals. It turns out that RNA is not just reading the DNA instruction and blindly follow it — the cell itself can also adjust what part of the instructions to perform. For this, it places a chemical marker on RNA, which adjusts the production of proteins.
Then he and his colleagues from China were concentrated on FTO, the first famous protein, which erases the chemical RNA labels. They already knew that in this way, the growth of human or animals cells can be launched, so they tried to introduce this gene in rice sprouts,
Then scientists repeated the experiment with potatoes, which belongs to a completely different family — Polenic. The results were similar, which makes it possible to conclude on the universality of technology.
«In addition to food, the climatic change has other consequences,» said Professor He. — Perhaps we could edit the grass in the arid regions. Or teach a tree in the middle west to grow longer roots so that it is less afraid of a strong wind. Potential applications are very much. «
In 2019, Japanese scientists for the first time
We tell about the most interesting news and technologies — from the upcoming total automation to alternative energy, from artificial intelligence to the future medicine.
