Outline of Final Research Achievements

In animals, the expression of cell cycle-specific genes is regulated by a super complex including multiple transcription factors. However, little is known about such a regulation mechanism in plants. In this study, I searched Arabidopsis genome for homologs of factors forming the super complex in animals, and carried out phenotypic observation and comprehensive gene expression analyses using the mutants of the homologous factors. The result showed the existence of the super complexes including some transcription factors in plants and revealed a part of the mechanism which comprehensively controls the expression of genes related to cell cycle regulation.
