Outline of Final Research Achievements

In general, bamboos have a very long vegetative phase and exhibit monocarpic mass flowering. Various mass flowering cases have been reported, but a molecular mechanism responsible for the mass flowering habit has not been revealed previously.
In this study, gene expressions were analyzed by using a quantitative real-time RT-PCR method in various organs during the course of yearly changes in the life history of Phyllostachys meyeri and Shibataea chinensis. The expressions of FT, SOC1, and TFL1/CEN homologs were detected in leaves, all tissue, and shoot apical meristem, respectively. In addition, the expressions of CO and Dof showed daily fluctuation and seasonal fluctuation, respectively in Phyllostachys pubescens.
