Welcome to the Kawashima Laboratory!

Although many factors involved in seed development and seed sizes/numbers have been identified, the precise mechanisms of how plants accomplish seed development and control these seed traits are largely unknown.  Using the confocal microscopy real-time live-cell imaging approach, we are investigating the molecular mechanisms, cellular dynamics, and evolution of land plant sexual reproduction, especially focusing on stages from fertilization to early seed/embryo development.
