Recent Activities

I am interested in how plants regulate the dynamic physiological responses that we can observe with our eyes. Currently, I am focusing on the molecular mechanisms in female papilla cells for successful pollination in Brassicaceae plants. In Brassicaceae plants, when non-self pollen attaches to the papilla cell during pollination, it hydrates by receiving water from the papilla cell. In contrast, self pollen does not hydrate. This phenomenon is called self-incompatibility. It is thought that several molecular events take place in the papilla cells when water is or is not transferred to the pollen. However, the events have not yet been fully elucidated. Therefore, my research aims to understand the mechanisms of water supply selectivity in the papilla cells of self-compatible/incompatible Brassicaceae plants.

Message to Students

I am looking forward to doing research together!
