Overview
Background
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.
