Outline of Final Research Achievements

Dormancy of the axillary buds and shoot branching in the inflorescence were analyzed at a molecular level. First, an experimental system to analyze the bud dormancy was established. By using this system, it was found that cell divisions were stopped in the whole area of the buds when they go to the dormancy state. On the other hand, cell division restarts when buds start to grow. Microarray analysis using laser dissected buds showed a possibility that ABA, Jasmonic acids and plant specific class of cell cycle inhibitors work downstream of Strigolactonn to control bud dormancy.
