Henan Daily Client reporter Cao Ping

"Cai Xuan and the basket." On July 26, Wang Xuelu, the vice president of Henan University at the beginning, before lectured on scientific research, he first read the poems in the Book of Songs.

"菽" is soybean. Thousands of years ago, we started occupying an important position on the table of the ancestors of the Yellow River Basin thousands of years ago, providing an important source of protein and edible oil for our ancestors. Today, Wang Xuelu and the team decode the mysteries of its growth and development and biological nitrogen fixation with the most advanced life science methods, and have achieved important results of breakthroughs.

Since the beginning of the university, it has been associated with plant science. For more than 30 years, Wang Xuelu has been immersed in the basic research of botanicals. He has gone through many cities and spans many fields. What is unchanged is the enthusiasm of scientific research and the original intention of punches.

It is difficult to see that Wang Xuelu has passed the destiny age when he is clean white shirt and a simple black -frame glasses. "To do scientific research, we must always maintain the curiosity and love of unknown, keep going to the pace of exploration, and take the path that others have not walked." This is probably his secret.

"Exploring unknown is the greatest charm of scientific research"

Today, Wang Xuelu's table is the most on the table. Returning to the country from the other side of the ocean, he moved to Henan and turned a lot. Wang Xuelu was getting closer and closer to his hometown, which made him feel kind and found the taste of his hometown.

Wang Xuelu is a giant deer in Hebei. He has been impressed by the story of breaking the boat in the "Battle of the Giant Deer" since he was a child, and every step on the road of scientific research has also been righteous.

In 1992, Wang Xuelu graduated from the graduate student of the Institute of Fine Arts of the Institute of Metal of the Chinese Academy of Agricultural Sciences and stayed directly to work. Three years later, Wang Xuelu resolutely resigned from a stable job and chose to study abroad. "At that time, the scientific research conditions and levels of our country had a huge gap compared with developed countries, that is, I hope to go to a more advanced and more advanced countries to learn and improve." Wang Xuelu recalled.

Leaving his hometown and walking away, Wang Xuelu entered the Department of Botanical Sciences at the University of Arizona for a doctorate degree to study the nutritional quality of corn.

It was a hard -working but pure years. Wang Xue passed a two -point life and devoted all his time and energy to learning and scientific research. When he had never been in the laboratory for three consecutive days, he had never been in the laboratory for a few years. At the same time, eight graduate students who entered school with him eventually, only Wang Xuelu persisted to the end and successfully graduated to get a doctorate degree. After graduating, he was engaged in post -doctoral research at the SALK Institute of Biological Sciences, San Diego, southwest of the United States. He used the model of plant Arabidophastin as a system of transforming plant hormone signals in the system.

In 2007, Dr. Wang Xuelu went out of the station and gave up the olive branches thrown from American universities. He chose to return to the country of Life Sciences, Fudan University. Wang Xuelu said the original intention: "The atmosphere of domestic entrepreneurial officers is particularly attractive. I hope to use what I have learned to add bricks to the basic study of botanical physics in my country."

In just two years, the first original research results of the Wang Xuelu team were published on the international journal PNAS; in 2009, Wang Xuelu was funded by the National Outstanding Youth Science Fund, and was selected as a special professor of "Yangtze Scholars" in the Ministry of Education in 2009.

Scientific research is what others have not done before. In 2014, Wang Xuelu turned to a new field and began to study soybean biology and his symbiotic nitrogen fixation mechanism. In order to better carry out scientific research, he moved to Huazhong Agricultural University and came to Henan University at the end of 2019.

"‘ Change the sea wide sky ’, the basic research of the bean family biology is a fertile soil that needs to be reclaimed. There are more problems to be resolved. Exploring the unknown is the greatest charm of scientific research." Wang Xuelu said.

"Being a study must look at the long -term"

After many years of research on botanical research, Wang Xuelu is not "dedicated". It has been involved from wheat, corn, naman mustard to rice. The research system includes physiological biochemicals, genetics, hormone signals and mutual, biochemical and molecular biology Wait. But when he was "rapidly turning" at the age of 47 and choosing biological nitrogen fixation and bean science as a research direction, many people were convinced by his courage.

Wang Xuelu did not have any hesitation or embarrassment. "Although the research objects have changed a lot, the fields are connected with the same knowledge. All previous research and achievements can be the basis of pioneering in a new direction. I believe that there will be a breakthrough in the new field." Wang Xuelu has a bamboo chest.

Henan is a large agricultural province and the origin of soybeans. Moreover, the first -class discipline fame of Biology of Henan University, as well as the newly built provincial and ministerial national platforms such as "crops adapt to and improved" national platforms. Wang Xuelu's determination to choose Bei Shang. "The scientific research environment here is very good, and it can lay out an excellent research team to lay out and organize an excellent research team." In 2019, Wang Xuelu came to Henan with confidence.

It turns out that Wang Xuelu's choice is not wrong. In October 2021, the research results of the Wang Xuelu team "The Mechanism of Soy Sominioma Tumor -induced Soy Bean Symbolic Tumors" was published in the international journal Science. It was the first paper published by the province's scientists in our province in the magazine; the result of the result; the result of the result; It is a major breakthrough in the field of biological nitrogen fixation. The results were selected as the "Top Ten Scientific and Technological Progress of Universities in China" in the Ministry of Education in 2021, achieving zero breakthroughs in this award in this award.

"The root of the beanic plants has a root tumor developed from the root tumor. They are like small green nitrogen fertilizer plants. The root tumor in the soil is hired '. Nitrogen is converted into ammonia, becoming nitrogen fertilizer that supports plant growth. This is biological nitrogen fixing. It can reduce the dependence of chemical nitrogen fertilizer through a large amount of coal coal, which is of great significance to develop green sustainable agriculture. "Oblical scientific nouns, the scientific nouns, Wang Xuelu said vivid and interesting. The series of research results of the Wang Xuelu team revealed how the light signal regulates the process of biological nitrogen fixing, and how the "employment" relationship between soybeans and root tumors is formed. "Based on this, you can design new types of plants that can also efficiently fix in dark and weak light, or cultivate better soy products through molecular breeding to increase yield. This is the charm and application prospect of basic research." Wang Xuelu said.

Basic studies are the keywords of Wang Xuelu repeatedly. "Many of the" card necks "problems currently facing our country are actually 'cards'. The vision depends on the long -term, looking forward to 30 or 50 years, consolidate the foundation of basic research, and attach importance to original innovation in order to not be caught in the future." Card "neck can truly achieve high -level technology self -reliance. "Wang Xuelu raised his voice.

"The most important thing for college development is talent"

Entering the crop adversity of the crops in Henan University adapting and improving the national key laboratory, you can hear the south and north transfer, and the members of the team come from all over the country.

There are many professors from Shanghai to Wuhan and follow Wang Xuelu to Henan University. Recently, Professor Jiang Jianjun, a newly introduced team, is from Sichuan. He studied undergraduate at Sichuan University. He is a PhD in Wang Xuelu in the laboratory of Fudan University. Later, he went to the United States for a postdoctoral study. The team is engaged in the study of nitrogen fixation of soybean.

Lu Qi from the laboratory was from Guangxi. She followed Wang Xuelu from Wuhan to Henan. "Teacher Wang is not only an academic teacher, but also our life mentor. It is not possible to care and urge everyone to develop. It is not possible to" lie down '. "Lu Qi smiled and said the reason why Wang Xuelu team condensed outstanding young talents.

Usually, Wang Xuelu asked students the most questions about "what is science" and "why do you do this subject." "You are not a worker on the assembly line. It is not duplicate to engage in scientific research. It must be innovative in scientific issues and research ideas, and it must be unique." Wang Xuelu admits that he is very strict with the students.

At the door of Wang Xuelu's office, there is a small table, which is the "topic discussion table" of him and the students. "Every half a month, we must talk to everyone in the laboratory at least once, talk about basic knowledge and scientific frontier, scientific issues and research ideas, confusion and difficulties." To communicate with students, Wang Xuelu never hesitated time.

In fact, Wang Xuelu has been filled very well. Not only is he responsible for the scientific research of the laboratory, he is also the vice president of Henan University.

More than two years ago, as soon as he arrived at school, he began to conduct in -depth investigations. "The development of first -class universities, discipline layout, first -class teachers' construction, first -class talent training, and output first -class scientific research results are the key. I am in charge of discipline construction, academic development and natural scientific research in the school leadership team." The experience of scientific research and student training and the study and work experience of multiple first -class universities and research institutes are important weights for his work.

Whether it is scientific research, bringing students, or planning the academic development of schools, Wang Xuelu seems to be familiar with it. However, the laboratory was on the lights of the early morning, witnessing his hardships and efforts; the densely hemp row was full of schedules, knowing his tension and busyness.

Wang Xuelu likes to carry a black backpack. The bag is always equipped with computers and materials to seize every gap to work and learn. "Small soybeans and root tumors have a lot of scientific issues that we don't understand, and there are many basic problems that have not been solved. We have to do a lot." Wang Xuelu's exploration will continue.
