About  us

The Department of Biochemistry and Molecular Biology was founded in 2012. Before then, it was part of the Department of Bioscience of College of Life Science & Technology, HUST. There are currently 11 faculty and staff members in the department, including 4 full professors and 5 associate professors. The faculty in the Department have undertaken research work funded by national "973" plan project, the national "863" project, the national transgenic major projects, the National Natural Science Foundation project, the key project of international cooperation in science and technology of  MOST and MOE of China. During past decades, great progress has been made in the field of  identification, expression and functional analysis of genes related to crop quality, abiotic stress tolerance, molecular breeding and cell signal transduction.

 

Research Areas

1. Molecular mechanism underlying milling and bread making quality and molecular breeding of wheat.

Group members: He Guangyuan; Yang Guangxiao; Wang Yuesheng; Chen Mingjie; Tu Zhiming; Chang Junli and Li Kexiu

The aim of this area is to identify and functionally characterize genes or mutant from wheat and its closely related wild species to reveal the underlying mechanisms of milling and bread making quality, as well as nutritional quality and using genetic engineering approach to breed new wheat varieties  suited for  different end-use, such as for bread, cake and steamed bread and new wheat varieties with high content of carotenoid.

2. Biochemistry and molecular biology of abiotic stress response in plants

Group members: He Guangyuan; Yang Guangxiao; Wang Yuesheng; Chen Mingjie; Tu Zhiming; Chang Junli and Li Kexiu

This area is focused on understanding how plants adapt to environmental stresses by using comparative genomics, proteomics, bioinformatics, physiological and biochemical approaches.  We focus on identification and functionally characterization of  genes encoding important signaling components such CBL/CIPK, CDPK, MAPK; transcription factors such as WRKY,AP2/ERF,NAC, MYB or functional proteins including AQP,LEA etc.
