| Outline of Final Research Achievements |
The pattern of the inflorescence (the branch on which the flowers arrive) is an important trait that affects plant appearance and crop yield and is determined by the timing of the transition of the meristem phase from indeterminate inflorescence meristem to determinate floral meristems. The rice APO2 and TAW1 were known to be important transcription factors that control inflorescence patterns through the control of the meristem phase change. In this study, we show that APO2 binds to the regulatory regions of a common set of genes and repeatedly controls these genes to determine the inflorescence pattern. We also found that TAW1 directly controls genes essential for floral meristem specification and maintenance of stem cells. Furthermore, we discovered that TAW1 functions are widely conserved in land plants.
