The magazine "Nature Genetics" reported on May 23, 2010 that a scientific research team composed of academician Li Jiayang of the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, and researcher Qian Qian of the China Rice Research Institute, Chinese Academy of Agricultural Sciences , successfully cloned a key gene that can help increase rice yield. The mutation of this gene can reduce the number of tillers, increase the number of grains per panicle and the weight of 1,000 grains, and at the same time make the stems thicker and increase the ability to resist lodging.
This achievement is included in China's top ten scientific and technological developments in 2010.
Has long been engaged in research on classical genetics, molecular genetics and breeding of rice. It was the first in China to carry out DNA fingerprinting to identify the authenticity of hybrid rice seeds. In cooperation with the Institute of Genetics of the Chinese Academy of Sciences, the rice single tiller gene and tender rice gene were successfully cloned, and a series of new trait genes were molecularly mapped. Proposed and participated in the breeding of the world's first photothermal sterile line with morphological markers, discovered multiple new specific germplasms, bred rice lines with new traits such as giant embryos, and a new type of feed rice - tender rice No. 1, completely changing rice. The traditional concept of simply being a food crop.
In 1998, he won the Zhejiang Provincial Youth Science and Technology Award. In the same year, he became the first batch of senior visiting scholars in the Knowledge Innovation Project of the Chinese Academy of Sciences. He is now a first-level talent in the 151 Cross-Century Talent Project of Zhejiang Province.
Two achievements won national-level science and technology awards, 7 achievements won provincial and ministerial-level science and technology awards and the Zhejiang Province Science and Technology Major Contribution Award
Won the Zhejiang Province Special Expert, Zhejiang Province Honors such as Young and Middle-aged Experts with Outstanding Contributions and Young and Middle-aged Experts with Outstanding Contributions of the Ministry of Agriculture, enjoy special government subsidies, Youth Science and Technology Awards of Zhejiang Province and Chinese Agricultural Society, selected as the first level of Zhejiang Province 151 Talent Project, and the first level of Outstanding Talents of the Chinese Academy of Agricultural Sciences Position candidates and the first level of the National Hundreds and Thousands Talent Project in the New Century.
Received funding from the National Outstanding Youth Fund and the National Foundation for Innovation Research Group, and presided over key projects such as the National 863, 973 and international cooperation.
Since 2001, he has published more than 110 SCI papers, 25 invention patents, and edited 3 monographs. He has given full play to the advantages of multidisciplinary cooperation in rice biology and penetrated biotechnology and genetic resources into the field of rice breeding. , forming distinctive research characteristics.
