| Outline of Final Research Achievements |
In order to identify the so-called death hormone, which is induced by flowering and functions to kill existing meristems, we have worked on epigenetic programs and hormone signaling in flower development. By utilizing transgenic lines developed by our laboratory, we have shown that KNU, a key gene for floral meristem determinacy, negatively regulates the stem cell determinant WUS in a two-step process. We also have developed biosensors for calcium, ATP and phytohormones to detect them quantitative manners in realtime of flower development.
