Assistant Professor

Ph.D. South China Agricultural University, China, 1997
B.S. Yangzhou University, China, 1985

Dr. Gu, a plant geneticist and seed molecular biologist, joined the faculty of the Plant Science Department at South Dakota State University (SDSU) in February of 2006. His research program has been focused on genetic variation of plant adaptation and its agricultural applications, with particular emphases on seed dormancy and photoperiod sensitivity. Dr. Gu is leading a seed molecular biology laboratory working with the seed dormancy, pre-harvest sprouting, and their interrelated characteristics in rice and wheat using quantitative trait locus (QTL) analysis, map-based cloning, and comparative genomics approaches. Dr. Gu is a member of Genetics Society of America and a new member of the Multistate Research Project W-1168 Environmental and Genetic Determinants of Seed Quality and Performance.
