Rice Functional Genomics and Agrobiotechnology

     The ChuLab mainly focuses on functional genomics and Agrobiotechnology by the use of rice as a model system. Besides tremendous efforts on germplasm collection, generation and screening of mutant population in last decades, the germplasms and mutants involved in agronomically important traits related to the plant architecture, source supply, and sink capacity, etc have been characterized, to dissect the molecular basis for rice yield improvement. Besides functional characterization of rice genes, we also make significant effort on Agrobiotechnology by using the knowledge, resources and tools obtained from our studies and combine approaches of genetics, molecular technologies, such as marker-assisted selection to improve complex agronomic traits. We are particularly interested in leaf senescence, grain size, nutrient use efficiency, the key agronomic traits in rice production.
