Outline of Final Research Achievements

A characteristic feature of flowering plants is the fusion of carpels, which results in the formation of a closed, vessel-like structure of the gynoecium. This closed structure contributes to protection of ovules inside, separation of the sites of pollination and fertilization, and promotion of seed dispersal. Using the model plant Arabidopsis thaliana, we have established an imaging method that is useful for in-depth analysis of carpel fusion at the cellular and molecular levels. We also analyzed structural and molecular changes associated with carpel fusion in detail.
