New breakthrough!Chinese scientists have discovered high -yielding of rice

In the early morning of July 22, the internationally renowned academic journal "Science" (Science "published an important gene OSDREB1C discovered by Researcher Zhou Wenbin, a researcher in rice in the form of a long text of the Chinese Academy of Agricultural Sciences.

ΔOSDREB1C is mature in advance (the right OSDREB1C expansion material, the left side is compared)

It is another high -yielding gene discovered by scientists in my country and will bring new dawn to the increase in production of global rice and other crops. Because the gene can simultaneously regulate multiple important biological channels, so that crops can be high -yield, nitrogen efficiently, and early maturity, breaking the contradiction between "high -yield, unsightly precocious, precocious precocious" in agricultural production. The research work provides genetic resources for the cultivation of more high -yield, efficient, and precocious crops. It also provides a feasible solution for crop production to greatly increase production and reduce nitrogen fertilizer application, and achieve "green and efficient".

The "high -yield gene" result released this time was led by Researcher Zhou Wenbin's team in the Institute of Fanke Department. It took 7 years to complete the genetic team. It was found that the genes with important high -yield potential in rice were found.

Molecular and physiological mechanism of ΔOSDREB1C transcription factor

The scientific research team found the gene in Beijing, Hangzhou, and Sanya in 2018-2022 that under the conditions of Beijing Chang Rizhao, the gene is expressed in the rice variety "Japanese sunny". God, an average increase in yield of 59.3%. Researchers further conducted functional verification in the main planted rice variety Xiushui 134. Hangzhou Datian test showed that the gene is expressed in Xiushui 134, which can make the dumping period at least 2 days in advance, an average increase of 35.2%.

Experts believe that the breeding application and industrialization application of this result is a very long process, and I hope the team will continue to cooperate. At the same time, it is also called on relevant departments to increase support and promote the transformation of the results.
