| Outline of Final Research Achievements |
In intact plants, the terminal bud grows predominantly, while the growth of the axillary buds is suppressed. This phenomenon is called apical dominance, which is a survival strategy in plants. This study is focused on the cell cycle regulation in comparison dormancy with growth in axillary buds. I identified the inhibitor of cyclin-dependent kinase (ICK) protein as a negative regulator in cell cycle control. Immunoprecipitation with anti-ICK antibody showed the protein complex in dormant axillary buds. After decapitation, ICK protein was degraded immediately in axillary buds. The levels of ICK protein were not affected with inhibitors of proteasome. These results suggested a part of molecular mechanisms of cell cycle regulation during the dormancy to growth transition in axillary buds.
