Zhao Yunde, assistant professor of the Department of Biology at the University of San Diego (UCSD), has adopted a new approach to study auxin and achieved a major breakthrough, opening up prospects for further development and application of auxin.
According to the World News Network of America, according to Zhao Yunde, people have long discovered that auxin has many effects. After auxin is applied to plants, the yield increases, the fruit becomes larger, and the growth period changes. The application of auxin can not only increase crop yield and improve the quality of agricultural products, but also weeding. In the early years, the defoliant "orange" used by the US military on the battlefield in Vietnam was actually an auxin.
Plant auxin has been discovered for more than 100 years. While people marvel at its many miraculous effects, they have not been able to find its mechanism of action.
Zhao Yunde emphasized that auxin is different from general growth hormones. It not only promotes the growth of plants, but also can change the shape of plants, and changes the color of flowers, the shape of leaves, and the location of root growth.
Zhao Yunde took a different approach, starting with chemical methods and combining with genetic theory, and found a new gene SIRI. When SIRI was added to the experimental plant "Arabidopsis thaliana", the originally flat leaves became trumpet-shaped, confirming the key role of SIRI in auxin.
Zhao Yunde, originally from Xiangtan City, Hunan Province, graduated from the East China Institute of Chemical Technology. After receiving a master's degree from the Shanghai Institute of Materia Medica, the Chinese Academy of Sciences, he went to study in the United States. After graduation, he went to the famous Salk Institute for plant research. His scientific training was very complete, laying a solid foundation for adopting new ideas to study scientific subjects.
