| Outline of Final Research Achievements |
In the Brassicaceae, intraspecific non-self pollen (compatible pollen) can germinate and grow into the stigmatic papilla cells, while self pollen or interspecific pollen are rejected at this stage. However, the mechanisms underlying this selective acceptance of compatible pollen remain unknown. Here, analysis of live-cell imaging and three dimensional tomography using Scanning Transmission Electron Microscope (STEM) visualized the interaction between cell membrane and interacellular memberane during compatible pollination, and biochemical analysis clarified the molecules interacting with Ca2+ transporter in the papilla cell membrane.
