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 tomato.

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

Biosynthesis of bio-active natural products

  • Enzymes and transporters for nicotine in tobacco
  • Herbivory activation of wound-signaling pathways for defense compound biosynthesis
  • Novel natural products in crop plants
