Biography

Li Jiayang, male, Han nationality, is a native of Feixi County, Anhui Province. He was born in 1956, and graduated from Anhui Agricultural University in 1982 with a Bachelor Degree then from Brandeis University of the USA with a Doctorate Degree in 1991.

Li made use of patterned plants, explored the regulation effect and its molecular mechanism of botanical endogenesis hormone and external environmental factors towards the growth of advanced plants. He set forth that direct anterior substances synthesized by arabidopsis botanical auxin (heteroauxing, IAA) mainly come from the intermediate products of the tryptophan synthetic channel indole-3-phosphoglycerol (IGP). He systematically appraised and studied the answering gene of rapeseed element lactone and discovered that the rapeseed element lactone can promote cell division through inducing the expression of cell cycle protein genes, which can substitute for cytokinin in the culture of rapeseed cell. Li advanced a presumption that there may exist a new rapeseed element lactone signal transducing channel in botanical cells. He developed a botanical expression library inversion method that contributes to systemically appraise botanical function cells. He also divided a batch of rapeseed mutants in which growth properties, such as plant type and fertility, incur alternation, and cloned related genes.

From 1999 to 2004, he was Director of Institute of Genetics and Developmental Biology, Chinese Academy of Science (CAS). Since 2004, he is Vice-President, Chinese Academy of Sciences.
