| Outline of Final Research Achievements |
Plant growth is controlled by the timing of transition from mitotic cell cycle to endoreplication. Therefore, to understand plant growth under fluctuating environmental conditions, it is important to know the molecular mechanism of endoreplication onset in plants. Previous studies reveal that CCS52A1, an activator of an E3 ligase, anaphase-promoting complex/cyclosome (APC/C), is involved in the control of endoreplication onset. Our study revealed that the induction of CCS52A1 gene is regulated by tissue-specific activation of cytokinin biosynthesis in response to environmental stress.
