Outline of Research and Education

We conduct extensive research, from basic to applied, concerning the cellular function, signal transduction and regulation of gene expression in higher-plants, making effective use of molecular genetics and imaging technology on Arabidopsis thaliana, tobacco, and tomatoes.

Major Research Topics

Dynamic reorganization of microtubule cytoskeletons in response to environmental stimuli and during plant growth

  • Pattern formation of bio-polymer networks
  • Regulators of microtubule dynamics
  • Left-right asymmetry establishment in cell shape
  • Stress-induced reorganization of microtubule arrays

Natural product biosynthesis and regulation

  • Transcriptional regulation of defense metabolism
  • Jasmonate signaling
  • Identification of novel enzymes and transporters
  • Plant metabolic engineering
