Tong Dizhou, male, born in May, 1902, is an outstanding biologist and educator in party member, CPC. Before his death, he served as vice president of China Academy of Sciences and director of Institute of Zoology. He is an outstanding experimental embryologist, the main founder of experimental embryology in China and an outstanding leader in biological science research. 1922 graduated from Xiaoshi Middle School in Ningbo. 1927 graduated from Fudan university, majoring in psychology, and worked as a teaching assistant in the biology department of Nanjing central university in the same year. 65438-0930, studying in Free University of Brussels, Belgium. 1934 received his Ph.D. from Free University of Brussels, then made a short visit to Cambridge University in England, and returned to China at the end of the year as a professor in the Biology Department of Shandong University. 1937 After the outbreak of War of Resistance against Japanese Aggression, he moved to Wanxian County, Sichuan Province with Shandong. 1938, National Shandong University moved to Qingdao to take over the production of private Qingdao University. Shanda changed its name to National Qingdao University, and he moved to Chongqing, where he successively served as a professor at Central University School of Medicine, Tongji University and Fudan University. After the victory of War of Resistance against Japanese Aggression, Shandong University moved back to Jinan from Qingdao on 1958. 1946, professor and head of the Department of Zoology, Shandong University. 1948 was elected as an academician of academia sinica. In the same year, he was invited by the Rockwell Foundation to be a visiting researcher at Yale University in the United States, and returned to National Shandong University in March. 1949. After the establishment of People's Republic of China (PRC), he continued to be a professor and head of the Department of Zoology of Shandong University. 65438-0950 Deputy Director of Institute of Experimental Biology, China Academy of Sciences, and Director of Qingdao Marine Biology Research Office, Institute of Hydrobiology, Chinese Academy of Sciences. 195 1 served as vice president of Shandong university. From 65438 to 0955, he was elected as an academician of China Academy of Sciences (now known as an academician) and served as deputy director of the Department of Biogeology. 1957, Director of Institute of Marine Biology, China Academy of Sciences. 1959, the Institute was expanded into the Institute of Oceanography of China Academy of Sciences, and he still serves as the director. During the period of 1960, the department of biology and earth sciences of Chinese Academy of Sciences was the Department of Biology and the Department of Geology. He is the director and researcher of the Department of Biology, Institute of Zoology, Chinese Academy of Sciences. 65438-0977, Director, Deputy Director and Director of Cytogenetics Research Office, Institute of Zoology, Chinese Academy of Sciences. 1978 vice president of China academy of sciences. In the past 50 years, he has been engaged in the research of experimental embryology, cell biology and developmental biology, and is one of the founders of experimental embryology research in China. He also served as the third to fifth NPC Standing Committee, vice chairman of the fifth China People's Political Consultative Conference and vice chairman of China Ocean and Lake Society. [Edit this paragraph] In his research on the embryonic development of amphibians (Bufo bufo gargarizans and Rana nigromaculata), he clearly pointed out the polarity phenomenon of embryonic development, thus proving that this perception ability was induced and determined by the infiltration of an unknown chemical substance between cells. He also contributed to the embryonic development ability and cytogenetics of fish. On the basis of mastering the necessary techniques such as feeding, oviposition and artificial insemination, his research team conducted a series of studies on the embryonic development mechanism of amphioxus, demonstrating that amphioxus belongs to an evolutionary transition type between invertebrates and vertebrates. When studying the relationship between nucleus and cytoplasm, he found that not only nucleus determines the development direction of cytoplasm, but cytoplasm also determines the fate of nucleus. The nucleus and cytoplasm are not completely isolated from each other, but have a very close relationship. They can communicate with each other in structure and induce and inhibit each other in function. This is the so-called theory of nuclear-cytoplasmic relationship. He also cooperated with Niu Manjiang, a Chinese-American scientist, to discuss the influence of crucian carp and its information RNA on the caudal fin of goldfish. The results show that this ribonucleic acid can induce the double tail of goldfish tail fin to become single tail. Therefore, it has opened up a research field worthy of further exploration in developmental biology and molecular genetics.
