Self-introduction
The aim of my research is to clarify the mechanism of epidermal cell differentiation in plants. I mainly study the transcription factors involved in the root hair and trichome differentiation of the model plant Arabidopsis thaliana. By elucidating the control network, I will understand plant morphogenesis and cell differentiation at the molecular level.
