Outline of Final Research Achievements

In this study, we aimed for the identification of new factors and mechanisms which cause the difference between annuals and perennials in plants. We utilized the transgenic Arabidopsis plants which acquired perennial-like features by overexpression of a transcription factor. We found that the perennial-like features were affected by both external factors, such as photoperiod and temperature, and internal factors such as production of splicing variants. These data suggested that this transcription factor function for Arabidopsis plants to properly grow as annuals under the regulation of external and internal factors. We also identified genes required for the transcription factor function to cause perennial-like phenotypes.
