The study, which began in 2011, found 1,445 new RNA viruses that greatly enriched the diversity of RNA viruses and revealed the basic laws of RNA virus generation and evolution from the perspective of genetic evolution. Some of these viruses are so different from existing known viruses that they need to be redefined as new viral families.
According to the statistics of the International Classification of Viruses, there are 2,284 DNA viruses and RNA viruses confirmed. The number of new viruses discovered by Zhang Yongzhen’s team has not only enriched the “database†of the virus, but also filled the main gap in the evolution of the virus. It also changed the traditional concept of virology and provided a new foundation for understanding the evolution of the origin of life.
In an interview with the Science and Technology Daily, Zhang Yongzhen said that in his decades of virus research, he has been working to analyze the relationship between newly discovered viruses and known pathogens, and to discover the law of its transmission and its pathogenicity to humans. This will help to improve the detection and screening of unknown viruses in the prevention and control of new and emerging infectious diseases in China, and also help to improve the clinical diagnosis ability of infectious diseases caused by unknown causes in China, and to confirm pathogens early, so as to achieve Targeted treatment. Zhang Yongzhen said that in the next step, he will cooperate with the hospital to use the latest findings in clinical diagnosis and provide assistance for researching diagnostic reagents and vaccines.
Gao Fu, deputy director of the China CDC and academician of the Chinese Academy of Sciences, said: "These findings have an important role in virus warning and prediction, and are closely related to human health."
Vegetable powder is a powdered vegetable particle made from vegetable raw materials that are dried and dehydrated first, and then further crushed; or first be mashed, and then spray-dried to be uniform. Covers carrot powder, tomato powder, potato powder, pumpkin powder, red beet powder, spinach powder, celery powder, yam powder and other vegetable categories. Weaned infants and young children cannot or cannot eat vegetables due to insufficient tooth development, elderly people are inconvenient to eat vegetables due to poor teeth or loss of teeth, and some adults reduce their intake of vegetables due to work or other reasons, so vegetable powder There is a wide market in this group of people. In addition, vegetable powder is also a pure natural coloring agent (carrot powder, tomato powder, spinach powder, red beet powder, celery powder, pumpkin powder, etc.), and is an excellent raw material for processed vegetable bread, vegetable noodles, specialty foods, etc. .
Vegetable powder can be applied to almost all areas of food processing, can be used to improve the nutritional content of food, and improve its color and flavor, etc.
