[Scientific Power] Lin Hongxuan: Work hard to ensure national food security in his life

According to research, the global average temperature increases by 1 ° C, which will cause wheat to reduce production by 6.0%, rice production is 3.2%, corn production is 7.4%, and soybean production is 3.1%. According to predictions, by 2040, high temperatures may reduce global food production by 30%to 40%.

In the face of global warming, how to use scientific means to ensure food safety? Academician Lin Hongxuan at the molecular and excellent innovation center of the Chinese Academy of Sciences, took the lead in the first in rice anti -complicated traits (anti -high temperature, drought resistance, salt resistance), and production complexity. The field of molecular genetic regulation mechanism research has achieved a series of breakthrough results with international levels.

"The ancestor of rice grows growing. After long -term domestication cultivation of rice, it has become growing up. What is the reason? This unsolved mystery was cracked until we found the gene that made the rice stand up '. . "What Academician Lin Hongxuan is looking for is the anti -inverse gene of rice. If such a" excellent "gene is excavated, it can improve rice resistance ability and achieve production increase.

This is exactly the direction of Lin Hongxuan's life.

In 1960, Lin Hongxuan was born on the Dongchang Farm in Hainan. In September 1979, he was admitted to the Dream of South China Agricultural College (now South China Agricultural University) agriculture, which gave him the opportunity to expose the mystery of genetics.

"Rice is a rations. At that time, there was a problem with food and clothing. The food was very tense. I wanted to study the significance of rice." When the undergraduate graduation design, each student had to choose a crop for research. As you can, Lin Hongxuan did not hesitate to choose rice.

In order to learn more about the knowledge of rice genetic breeding, Lin Hong announced that he applied for the Graduate School of the Chinese Academy of Agricultural Sciences and came to the China Rice Institute for further studies. After that, he obtained a doctorate. Lin Hongxuan recalled, "At that time, I was married, and the children were still young. They all read the book after the child was sleeping." In August 1997, Lin Hongxuan went to the Japanese National Agricultural Biological Resources Institute of Rice Genome Project (RGP) for postdoctoral research.

In this way, from graduating from undergraduate, Lin Hongxuan embarked on the scientific research path of "making rice", and it was nearly forty years.

After nearly 10 years of hard work, Lin Hongxuan led the scientific research team to achieve the latest research results -successfully discovered the first potential crop "high temperature feeling" in the world. In the future, with the help of molecular biotechnology methods, the new anti -high temperature genes that are excavated in this study can be applied to the improvement of high -temperature breeding of rice, wheat, corn, soybean, and vegetables, improve the high temperature resistance of different crops, and maintain it, maintain maintenance, and maintain it. Its output stability at extreme temperature. This is of great significance to effectively respond to the grain safety issues caused by global warming.

Lin Hongxuan said that they have successfully tapped multiple rice genes and obtained patents. Brexies can make full use of the seeds of these genetically modified crops. For example, you can use molecular biotechnology methods to apply the seeds of TT1, TT2, TT3.1/TT3.2 to improve the seeds of crops such as improvement of rice, wheat, corn, and vegetables to improve the heat resistance of crops and maintain the extremes of cropy, maintain the extremes of cropy, and maintain the extremes of extremes, maintain extremes in extremes. The stability of crop yields under high temperature weather has a wide range of application prospects on grain safety issues caused by global warming.

"In the future, we will continue to dig out more favorable genetic sites from various types of rice species of rice species, to deeply reveal the regulatory mechanism and regulation network of complex and quantitative properties of rice, continuously absorb new technologies and new methods, accelerate research progress, seize agricultural agriculture Intellectual property high ground provides new genetic resources and new knowledge for crop molecules, and contributes to the revitalization of the breeding industry in China and ensuring my country's food security. "Lin Hongxuan said.
