Decoding papaya "password" to create "biochip"

Hawaii is beautiful in the United States and produces papaya.
Today, U.S. research institutions are working with Chinese experts to jointly decipher the papaya “password”.
The "Papaya Genome Sequencing Project" co-chaired by the University of Hawaii and Nankai University's TEDA Institute of Biotechnology started more than a year ago. All work has progressed smoothly and 85% of the genome sequencing tasks have been completed.
This international cooperation is the first time in the world to decipher the whole genome of woody cash crops. It is also a large-scale genome decipherment work after China’s scientific community participated in the deciphering of the human genome and the whole genome of super hybrid rice. It is reported that more than five million US dollars worth of research funds for this research project will be provided by the United States, and the research results will be jointly owned by both parties.
The University of Hawaii’s genomics research is world-renowned. Why do they "dissect" their "specialties" and pull up Chinese experts?
On June 11th, Dr. Wang Lei, Professor of the “Cheung Kong Scholars” Program of Nankai University and Dean of TEDA College of Biotechnology once again set out for Hawaii to discuss issues with US partners. When interviewed by reporters before his departure, he said that it is our strength in the field of genomics research that has won each other’s respect and trust; and this high-level international cooperation has also contributed to the development of the discipline and the improvement of its own research. Provides a great opportunity and platform.
On Wang Lei’s business card, three titles are printed side by side: “Dean of TEDA Biotechnology College of Nankai University”, “Director of Functional Genomics and Biochip Research Center of Tianjin”, and “Director and General Manager of Tianjin Biochip Technology Co., Ltd.” The interpretation of the perfect combination of "science and research production."
In the field of domestic biotechnology, Wang Lei is notoriously famous. In the biochip known as the 21st century revolutionary technology, the team led by Wang Lei took up two “one fifth”: The Tianjin-based functional genome and biochip research center he led was included in the national “863” plan. One of the five biochip research and development bases supported by major projects; they have a unique advantage in searching for specific DNA molecular markers for pathogenic microorganisms. They possess probe technology that can be used to manufacture biochips from DNA molecules encoding specific antigens. The only five institutions that have mastered this core technology.
Complaining, Wang Lei returned to China for less than 5 years.
A trip to Tianjin in September 2001 inadvertently rewritten the life trajectory of Wang Lei. At the time, Wang Lei, who was in charge of microbiological direction at the Australian CRC Microarray Center (University of Sydney), was invited to return to his alma mater Nankai University to hold an academic lecture. At that time, Tianjin City also set its sights on the newly emerging biochip industry. This idea coincides with Wang Lei’s interest.
Wang Lei’s impulse to return to China after returning to his home country was separated by only three months. What touched him was that the relevant authorities in Tianjin paid great attention to it and immediately allocated RMB 1 million as a special fund to support the development of biochips. Later, Tianjin Economic and Technological Development Zone gave great support from policies, funds and other aspects, and joined hands with Tianjin Zhongxin Pharmaceutical, Tianjin Venture Capital and Nankai University to jointly invest 100 million yuan to initiate the establishment of Tianjin Biochip Technology Co., Ltd. This industrialization platform. At the same time, Nankai University established the TEDA College of Biotechnology and reformed the personnel and administrative management mechanism. This enabled the college to gather a high-level research echelon from around the world in a relatively short period of time.
Unlike a semiconductor chip, a biochip is like a "glass piece" with a long finger. But it is not an ordinary piece of glass, dotted with a large number of DNA molecules.
Wang Lei said that biochip technology is the result of combining traditional molecular hybridization methods with modern high-density microarray methods, enabling accurate, rapid, and large-quantity detection of DNA (and proteins). In recent years, around biochip technology, they have published 25 high-level papers in authoritative international microbiology publications, applied for 108 Chinese patents for inventions and applied for 4 international invention patents. By now, they have obtained 57 Chinese patents for inventions and become domestic ones. The field of "biological patents" in the field of biochips. These achievements will allow China to be at the forefront of the world in the field of microbiological molecular detection for a period of time.
