Short Biography

Dr Qunyi Jiang has been active in the research field of molecular genetics and genomics of model legume Lotus japonicus for the last 10 years at UQ. This has focused on understanding the autoregulation of nodulation, root development, gene-gene interaction and crossing talk between ethylene and cytokine in L. japonicus. Qunyi is currently conducting research with colleagues on improvement of growth, adaptability and sustainable biofuel and bioenergy production of Pongamia pinnata using the platform of biotechnology-genetics-genomics.

In addition to research projects, Qunyi had concurrently taken the role as laboratory manager to coordinate laboratory functions with Director, CILR during 2003-2007, and is holding same role in 2012.

Research Skills

  • Molecular cloning
  • DNA marker technology
  • Vegetative propagation of Pongamia

Current Project

  • To develop molecular DNA marker technique for the purpose of genetic mapping, molecular breeding and gene discovery.
  • To develop inbred/hybrid lines for domesticated Pongamia through sexual hybridisation techniques.
  • To establish an arboretum using vegetative propagation of elite as well as phenotypically distinct trees through tissue culture, grafting and cutting.
  • To create a data base for seed component phenotypes (oil, protein, and starch content) of Pongamia trees grown in different geoclimatic regions.
