Overview

Dr. Guoquan Liu has more than ten years experience in sorghum tissue culture and genetic transformation. He developed a highly efficient sorghum particle transformation system in 2012. Since then, hundreds of transgenic plants have been regenerated from tens of constructs that are invoved in plant disease resistant genes (e.g. Lr34), report gene (gfp), specific-promoters (e.g. alpha- beta- kafirin, A2, LSG), G proteins etc.. He has trained many students how to transform sorghum including honor students, master students, and PhD students.

He has focused on improving sorghum grain yield and grain quality through biotechnologies including genetic transformation, genome-editing, synthetic biology, and plant apomixis.

Research Interests

  • Plant Tissue Culture
    Optimize tissue culture system for transformation and genome editing.
  • Plant genetic transformation
    Investigate and characterize gene function.
  • Plant genome editing
    Investigate and manipulate gene function for improving grain size and grain quality in sorghum.
  • Plany synthetic biology
    Design and synthesize genes for plant engineering in sorghum.
  • Biofuel
    Increase total sugar content and improve plant biomass in sorghum.
  • Capture heterosis
    The project is proudly funded by the Bill & Melinda Gates Foundation and predominantly focus on fixing heterosis in sorghum and cowpea.

Research Impacts

Highly efficient sorghum tissue culture and particle bombardment transformation system.
