Research Activities
In plants, each cell has the capacity to reproduce a new individual (totipotency). Each cell can develop specific functions through the processes of cell division, growth and differentiation, and through the assembly of these cells, individuals are organized. In our laboratory, we try to understand the mechanisms by which individual plants are formed through the study of cell morphogenesis, mainly using tobacco BY-2 cells.

Future Plan
Our laboratory’s approach to this research is to us e structure-visualized cells and 3D imaging to understand the plant cell morphogenesis.
Messages to Students
We hope that young students will join us in our mission of furthering pure sciences in plants.
