Outline of Research and Education
We conduct extensive research, from basic to applied, concerning protein function, cell morphogenesis, signal transduction and regulation of gene expression in various plants, making effective use of molecular genetics and imaging technology on Arabidopsis thaliana, liverwort, and green algae.
Major Research Topics
Dynamic reorganization of microtubule cytoskeleton in response to environmental stimuli leading to stress adaptation
- Pattern formation of bio-polymer networks
- Regulators of microtubule dynamics
- Stress-induced reorganization of microtubule arrays
- Stress-signal transduction leading activation of tubulin kinase
- Novel growth arrest mechanisms by microtubule disassembly
Why and how plant pavement cells adopt a jigsaw puzzle-like shape?
- Microtubule regulators generate complex cell shapes
- Bio-mechanics for local growth anisotropy
- Physical advantages for complex cell shapes
